A research team, led by Professor Hwang Seung Kook of the Department of Information and Communication AI Engineering at Kyungnam University, revealed on May 14th that his team has succeeded in developing a quantum dynamo product that can work as a motor and, at the same time, produce electricity without overload.
Hwang’s team announced the development of “quantum power generation technology” on December 29th, 2021, and signed an agreement with TRC (The Ruby co.) Electric Engineering Service Company on making ultra-high efficient quantum power generator. The first product for commercialization of the technology is a quantum dynamo, the characteristic of which is to generate electricity without overload through ways of quantum array of existing motors.
Normally a motor and a generator are used separately. If used together, they stop working due to overcharge caused by load, which renders simultaneous use of them impossible.
The motor converts electric energy into kinetic energy when the coils, helped by the power of magnetic field, rotate a rotor. The magnetic field is created by electric current passing through the coils of the rotor. The generator works the opposite way of the motor in terms of energy conversion.
A quantum dynamo is a new type of power generator-motor which rotates when power is injected into the motor itself and keeps generating power without a load phenomenon when load is applied immediately after power input. A test result proves it.
This opens the way to transforming existing motors, which have decreasing efficiency due to overload, into ultra-high efficient ones.
The automobiles so far produced range from internal combustion engine (ICE) car which uses fossil fuels, hybrid electric vehicle (HEV) and Plugin Hybrid Electric Vehicle (PHEV) which use both fossil fuels and batteries, electric vehicle (EV) which uses batteries, and fuel cell electric vehicle (FCEV) which uses hydrogen and batteries.
The quantum dynamo, if equipped in electric vehicles, distinguishes itself from the one in existing vehicles in the following aspects:
First, if charged only once, the dynamo continues self-generating of its power without external power supply. This enables discharge and charge of power simultaneously while driving.
Second, it has simple structure of quantum dynamo and battery.
Third, it excels in safety and price competitiveness compared to lithium batteries since it can use alkaline batteries of existing ICE cars.
Fourth, while existing EVs need to be charged repeatedly with electricity made from fossil fuels, vehicles equipped with the quantum dynamo need to be charged only once and do not require further supply of power.
It is expected that the quantum dynamo that Professor Hwang’s team developed can be one of environmental friendly C-Tech solutions that solves climate change, which is very necessary at this juncture to achieve Net Zero by 2050.
Other applications include drones, electric kickboards, vacuum cleaners as well as UAM (Urban Air Mobility) which receives a lot of attentions as means of future innovative transportations. It seems that the technology will attract interests of businesses and users in these related industries, too.
