Across Australia’s water and wastewater sector, electric motors are at the heart of essential infrastructure. From moving clean water through municipal supply systems to managing wastewater treatment processes in industrial facilities, reliable motor technology plays a critical role in maintaining efficiency, safety, and operational continuity.

At Edington Agencies, we understand the importance of dependable electric motor solutions for demanding water and wastewater environments where uptime, energy efficiency, and durability are non-negotiable.

The Importance of Electric Motors in Water & Wastewater Operations

Water treatment plants, pumping stations, desalination facilities, and wastewater processing sites rely heavily on electric motors to keep systems operating around the clock. These motors drive a wide range of equipment including:

Water transfer pumps

Bore pumps

Aeration blowers

Filtration systems

Sludge handling equipment

Conveyor systems

Mixers and agitators

Chemical dosing systems

Without efficient motor systems, water infrastructure would struggle to meet the increasing demands of growing populations, environmental regulations, and energy management requirements.

Common Applications of Electric Motors in the Industry

Pumping Systems

Pumps are among the most critical assets in any water or wastewater facility. Electric motors are used to power centrifugal, submersible, and booster pumps that transport water through treatment and distribution networks.

In wastewater applications, motors must often operate in harsh environments involving moisture, corrosive chemicals, and continuous-duty cycles. High-quality industrial motors provide the reliability needed to minimise downtime and costly maintenance interruptions.

Aeration Equipment

Aeration is essential in biological wastewater treatment processes. Electric motors drive blowers and compressors that introduce oxygen into treatment tanks, helping bacteria break down organic waste efficiently.

Because aeration systems can consume a significant portion of a facility’s energy usage, selecting energy-efficient motors can deliver substantial operational savings over time.

Mixing and Agitation

Treatment plants frequently use mixers and agitators to maintain consistent chemical balances and prevent solids from settling in tanks. Electric motors used in these applications must provide precise and reliable torque while withstanding continuous operation.

Sludge Processing

Wastewater facilities also rely on electric motors for sludge pumps, dewatering systems, centrifuges, and conveyors. These demanding applications require robust motor performance and dependable operation in abrasive conditions.

Why Energy Efficiency Matters

Energy consumption is one of the largest operational costs in water and wastewater treatment facilities. Modern high-efficiency electric motors help reduce power usage while maintaining strong performance.

Benefits of energy-efficient motor systems include:

Reduced electricity costs

Lower greenhouse gas emissions

Improved system reliability

Reduced maintenance requirements

Longer equipment lifespan

Compliance with sustainability initiatives

Variable speed drives (VSDs) are also commonly integrated with electric motors to optimise motor speed based on system demand, further improving energy efficiency and reducing wear on equipment.

Choosing the Right Motor for Water & Wastewater Applications

Selecting the correct motor involves considering several operational factors, including:

Environmental exposure

Duty cycle requirements

Power demands

Corrosion resistance

Temperature conditions

Moisture protection ratings

Energy efficiency standards

Motors used in water and wastewater facilities often require specialised protection against dust, humidity, chemicals, and washdown conditions. Proper motor selection helps improve operational reliability and reduce lifecycle costs.

Supporting Critical Infrastructure

Water and wastewater systems are essential services that communities and industries depend on every day. Reliable electric motor technology helps ensure these facilities can continue operating efficiently while meeting environmental and operational standards.

At Edington Agencies, we supply high-quality electric motor solutions designed to support demanding industrial applications across the water and wastewater sector.

With electricity prices in Australia continuing to rise, “Electronically Commutated” (EC) technology is no longer just a luxury—it’s a financial strategy. But is it right for your Brisbane facility?

The EC Difference Traditional AC motors run at a fixed speed unless controlled by an external VSD. EC motors (like those from our partners at Ziehl-Abegg) have integrated electronics that allow for precise speed control.

The ROI Breakdown:

Energy Savings: An EC fan can be up to 30% more efficient than a standard AC motor at full load, and significantly more efficient when “turned down” during off-peak hours (like at night in a commercial office).

Reduced Complexity: Because the speed control is built-in, you don’t need a bulky external VSD cabinet, reducing installation costs and electrical “noise” (harmonics) on your site.

Longevity: EC motors run cooler, which directly translates to a longer lifespan for the bearings and internal components.

When an HVAC fan stops spinning, the most common call-out is a “dead motor.” But before you quote your customer for a full motor replacement, it’s worth checking the hum.

The “Hum” Test If the motor is humming but not turning, it’s often a sign that the motor’s windings are fine, but the starting capacitor has failed. In the Queensland heat, capacitors are often the first component to degrade.

How to tell the difference:

The Capacitor: Look for bulging, leaking oil, or “burnt” terminals. Using a multimeter with a capacitance setting, check if the microfarad (µF) reading matches the label. If it’s more than 10% off, it’s time for a new one.

The Motor: If the shaft is difficult to turn by hand (with power off!), the bearings have likely seized. If there is a strong smell of burnt lacquer, the internal windings have likely cooked.

It is a scenario every facility manager in Brisbane dreads: a critical fan or pump motor fails, you look at the nameplate, and the manufacturer has been out of business for a decade.

When you can’t buy a “like-for-like” replacement off the shelf, the temptation is to modify the mounting or the ducting. However, this is often the most expensive and time-consuming route. At Edington Agencies, we specialise in the “Cross-Reference” — finding a modern, high-efficiency equivalent that fits your existing footprint.

The Edington Roadmap to Replacement:

Frame Size and Mounting: We start by identifying the IEC frame size or the specific NEMA mount. If it’s a bespoke HVAC motor (like an old Fasco or GE model), we look at the “belly-band” or stud mounting details.

Electrical Characteristics: We match the kilowatts (kW), speed (RPM), and voltage. In many cases, we can upgrade you from an older, inefficient motor to a modern MEPS-compliant Marathon or WEG unit that reduces your energy bill.

Shaft Dimensions: This is where most DIY replacements fail. We ensure the shaft diameter and length match your existing pulley or fan blade precisely.

Blauberg is a German ventilation brand known for inline duct fans, heat recovery units, and other air movement products. They’re popular in Europe for residential, commercial, and light industrial ventilation.

🔧 What are inline fans?

Inline fans are installed inside a duct — they boost airflow through ventilation ducts for:

Bathrooms, kitchens, or utility rooms

Whole-house or apartment ventilation

Grow rooms or greenhouses

Industrial or commercial ducting

⚙️ Blauberg inline fan types

Typical Blauberg inline fan ranges include:

1️⃣ Mixed-flow fans (e.g., Blauberg Turbo, Blauberg Iso-Mix)

Compact, high pressure, higher airflow than axial fans.

Good for medium-length ducts with moderate resistance.

Quieter than standard axial fans.

Often used in residential or light commercial ductwork.

2️⃣ Centrifugal inline fans (e.g., Blauberg Centro, Blauberg Iso-Vent)

Higher static pressure.

Good for longer ducts with bends and filters.

Usually quieter due to better sound insulation — many models have acoustic insulation (Iso versions).

3️⃣ Axial inline fans (e.g., Blauberg Inline)

Basic fans for short, straight ducts.

Low pressure, high airflow.

Simple and cost-effective for straightforward extraction.

✅ Key features

Available with single-speed, multi-speed, or EC motors.

Many models have backward-curved centrifugal impellers.

Some have built-in thermal protection.

Some come with built-in sound insulation for quiet operation.

EC models are more efficient and can be controlled by 0–10 V signals or potentiometers.

📐 Applications

Residential: Bathrooms, kitchens, air extraction.

Commercial: Offices, shops, restaurants, server rooms.

Special: Hydroponics/grow tents (very popular in that market).

🔌 Installation tips

Use flexible connectors to reduce vibration noise.

Mount with anti-vibration mounts if needed.

Install access for cleaning/maintenance.

Size the fan for your duct diameter and airflow requirements.

Consider backdraft dampers if needed to prevent unwanted airflow.

🔊 Noise

Inline fans can create duct-borne noise → add silencers if needed.

1️⃣ Preparation

Check nameplate: Confirm voltage, frequency, power, and enclosure type match your application.

Inspect motor: Look for shipping damage, check shaft turns freely, and seals are intact.

Verify site conditions: The mounting base must be level, rigid, and strong enough to handle weight and torque.

Environmental check: Is it clean? Dry? Ventilated? Does the IP rating match the surroundings?

2️⃣ Mounting

Align the motor on its base or mounting feet.

Ensure base is flat and level — uneven mounting causes misalignment, vibration, and bearing stress.

Use shims if needed to level the motor.

Bolt motor down securely but don’t overtighten — use lock washers or thread-locking compound to prevent loosening.

3️⃣ Alignment

For direct-coupled loads (e.g., pumps, compressors):

Align the shafts precisely in both angular and parallel planes.

Use a dial indicator or laser alignment tool — don’t rely on eyesight alone.

Misalignment = vibration, heat, bearing/bushing damage.

4️⃣ Coupling

Fit the coupling according to manufacturer instructions.

Leave correct end float and clearance.

For belt drives: Align pulleys, set correct belt tension — too tight damages bearings; too loose causes slip.

5️⃣ Electrical connections

Use correct cable size for the motor’s current and distance.

Connect per wiring diagram — especially for dual-voltage motors (e.g., star/delta or series/parallel connections).

Use appropriate terminals, lugs, and cable glands to maintain enclosure integrity (IP rating).

Bond the motor frame to earth ground properly.

6️⃣ VSD/Soft Starter (if used)

Check compatibility with motor type.

Use shielded cables if required.

Install EMC filters or line reactors if specified.

7️⃣ Cooling & ventilation

Make sure air inlets and outlets are clear — no obstructions.

For TEFC (totally enclosed fan-cooled) motors, ensure the fan cover is intact.

For forced ventilation or external fans, wire them correctly.

8️⃣ Testing before startup

Insulation resistance test (megger) — check winding insulation to ground.

Rotation check — bump the motor briefly to verify direction.

Check all bolts, couplings, guards are secure.

Confirm overload protection settings match motor FLC (Full Load Current).

9️⃣ Startup

Monitor current draw during first run.

Listen for abnormal noise, vibration, or overheating.

Verify operating temperature stays within limits.

🔧 Key best practices

✅ Align properly — most common source of failures is misalignment. ✅ Use proper earthing and bonding. ✅ Follow local electrical codes (NEC, IEC, or equivalent). ✅ Keep a record: installation checklist, test readings, photos.

⚡ Common mistakes to avoid

Variable Speed Drives (VSDs) are used to control the speed of motors by adjusting the frequency and voltage supplied to the motor. While they offer significant energy savings and process control benefits, they can also introduce issues, one of which is bearing currents.

Let me break down the relationship between VSDs and bearing currents and how they can impact motor performance.

What Are Bearing Currents?

Bearing currents are unwanted electrical currents that flow through the bearings of electric motors. These currents can damage the bearings over time, causing wear and ultimately leading to premature motor failure. They are a common issue in motors controlled by VSDs.

How VSDs Cause Bearing Currents

VSDs generate high frequency switching signals to control motor speed. These switching signals can create electrical noise or high-frequency voltage spikes. These spikes can then travel through the motor’s shaft and cause currents to flow through the bearings, especially in motors that are not properly insulated.

Mechanism:

PWM (Pulse Width Modulation) Switching: VSDs typically use PWM techniques to control the motor speed. The rapid switching of the PWM signal can cause voltage imbalances that create high-frequency currents. These currents can find their way to the motor shaft.

Stray Capacitance: The motor’s stator windings can form a capacitive coupling to the motor shaft. This can allow high-frequency current to flow from the stator through the motor bearings.

Impacts of Bearing Currents

Electrical Discharge Machining (EDM): Bearing currents can cause localized pitting or erosion of the bearing surfaces, similar to a process known as EDM. Over time, this can degrade the bearing material and cause significant damage.

Premature Bearing Failure: Continuous bearing currents can lead to wear and fatigue, resulting in bearing failure much earlier than expected.

Noise and Vibration: In some cases, bearing currents can also introduce vibrations or audible noise in the motor.

How to Mitigate Bearing Currents

There are several methods to prevent or reduce bearing currents in motors driven by VSDs:

Insulated Bearings: Using insulated bearings, typically ceramic bearings, can help prevent the flow of electrical current through the bearing. The insulation prevents the motor shaft from directly contacting the bearing races, thereby preventing current flow.

Shaft Grounding Devices: These are commonly used to provide a low-resistance path for the bearing currents to flow safely to ground. Examples include:

Shaft grounding rings (often made of conductive carbon or copper)

Brushes mounted on the motor shaft to conduct the current away from the bearings.

Filters: Using a line reactor or a motor filter on the output of the VSD can help reduce the high-frequency voltage spikes generated by the drive, thereby reducing the possibility of bearing currents.

VSDs with Output Filters: Some modern VSDs come equipped with built-in output filters or features that reduce the switching frequency, which can also help reduce bearing currents.

Proper Grounding: Ensure that the motor and the VSD are properly grounded to prevent electrical noise and stray currents.

Additional Considerations

Type of Motor: Certain motor types, such as those with long shafts, are more susceptible to bearing currents due to the larger surface area and potential for voltage imbalances.

Motor Condition: Older motors with worn bearings or insulation may be more prone to damage from bearing currents, even if the VSD is operating correctly.

Motor efficiency (η) is the ratio of mechanical output power to electrical input power. It shows how well a motor converts electricity into useful mechanical work.

Efficiency=Mechanical Output Power/Electrical Input Power×100%

Typical efficiencies

Small AC motors (fractional HP, <1 HP): 60% – 80%

Medium industrial AC motors (1–100 HP): 85% – 95%

Large industrial AC motors (>100 HP): 95% – 98%

High-efficiency or premium-efficiency motors: can reach 96%–98%

What affects motor efficiency?

Motor size: Larger motors are usually more efficient.

Load: Motors run most efficiently at 75%–100% of rated load.

Design: High-quality bearings, better materials, tight air gaps, and improved winding design reduce losses.

Motor type: Induction, synchronous, BLDC, universal — each has different typical efficiencies.

Operating conditions: Voltage imbalance, poor maintenance, or heat can reduce real-world efficiency.

 How to improve motor efficiency

Use premium-efficiency motors (meeting IE3/IE4 standards).

Keep motors properly sized — avoid underloading or oversizing.

Maintain regularly (lubrication, alignment, cooling).

Use variable frequency drives (VFDs) for speed control in variable-load applications.

Reduce mechanical losses (good couplings, alignment).

What are IE2, IE3, and IE4?

These are International Efficiency (IE) classes defined by the IEC 60034-30 standard for low-voltage three-phase electric motors. They’re widely used worldwide (Europe, Asia, many other regions).

IE1: Standard Efficiency (often phased out)

IE2: High Efficiency

IE3: Premium Efficiency

IE4: Super Premium Efficiency

⚡ How do they compare?Motor Size (Example: 4-pole, 50 Hz)IE2IE3IE47.5 kW motor~89.6%~91.7%~93.1%15 kW motor~91.0%~92.6%~94.1%75 kW motor~94.1%~95.4%~96.3%

(Exact values depend on standards and manufacturer, but this is typical.)

Key point: Going from IE2 → IE3 often gains 2%–3% efficiency. Going from IE3 → IE4 gains about 1%–1.5% more.

 What’s the impact of these small % gains?

A few percent means:

Lower losses (waste heat) → Less cooling needed, longer motor life.

Lower energy cost: Motors often run thousands of hours per year. Even 1% can mean big savings over time.

Lower CO₂ footprint if your energy source isn’t fully green.

Other differencesIE2IE3IE4CostLowest~10–20% higher than IE2~20–40% higher than IE3Weight/sizeStandardOften slightly larger or heavier (more copper, better iron)Even more advanced design/materialsAvailabilityStill used in some regionsNow minimum standard in EU for many motorsBecoming common for top-tier applicationsUse caseGeneral industrialStandard for new installationsHigh-efficiency/green buildings, big energy savings

Bottom line

For new industrial projects, IE3 is now the legal minimum in many countries (e.g., EU Ecodesign rules).

IE4 is good for premium systems, heavy running hours, or where energy cost is a big concern.

Side channel blowers, also known as regenerative blowers or ring blowers, are devices used for moving air or gas with moderate pressure. They are commonly employed in applications that require continuous airflow and a vacuum or pressure, such as pneumatic conveying, vacuum lifting, aeration, and more.

Key Features:

Operating Principle:

Side channel blowers work by trapping air in the space between the blades of an impeller and the housing (side channel). The impeller rotates, accelerating the trapped air, which creates a pressure increase as the air moves along the channel.

Non-Contact Design:

The impeller does not touch the housing, so there’s no wear due to friction, leading to low maintenance.

Pressure and Flow:

These blowers provide higher pressures than centrifugal fans but lower flow rates than typical industrial blowers.

They can generate pressures up to 1,000 mbar (14.5 psi) and vacuum up to -500 mbar.

Typical Applications:

Pneumatic conveying: Used to move granular materials like powders and grains.

Wastewater aeration: Provides oxygen in water treatment processes.

Vacuum lifting systems: Used in packaging or handling to lift objects via vacuum suction.

Cooling and drying systems: Help to cool or dry products in industries like plastics, paper, or food processing.
