Linear Drives vs Linear Motors: Choosing the Right Option
https://www.youtube.com/watch?v=r18AFn_0mi0
Linear motors explained — how direct-drive linear motion really works.
In this video, we explain what a linear electric motor is, how a linear electromagnetic motor works, and when it makes sense to use a linear motor instead of a mechanical drive such as a linear drive screw.
A linear motor generates motion directly in a straight line. Unlike conventional systems, there is no spindle, belt, or gearbox between the motor and the load. Force is produced electromagnetically and applied directly to the axis, resulting in highly precise and repeatable motion.
What you’ll learn in this video:
• The working principle of a linear electric motor
• How linear motors and actuators differ from mechanical linear drives
• Why direct-drive systems eliminate backlash and mechanical wear
• When a mechanical linear drive screw is sufficient—and when it becomes a limitation
• Typical applications where linear motors clearly outperform mechanical solutions
Linear motors vs. mechanical linear drives:
Mechanical linear drives are widely used for basic positioning tasks. They are robust and cost-efficient, but friction, backlash, and wear limit their performance—especially at higher speeds or tighter accuracy requirements.
A linear electromagnetic motor, on the other hand, produces force without mechanical transmission. This direct-drive principle enables:
• No backlash
• No mechanical wear
• Stable accuracy over millions of cycles
• High speed and dynamic response
That is why linear motors are used in precision automation, inspection systems, assembly processes, and compact industrial machines where motion quality is critical.
Integrated linear motor systems:
At Jenny Science, linear motor axes such as LINAX® and ELAX® are engineered as integrated direct-drive units. Motor, guide system, and feedback are optimized together as one compact axis, ensuring predictable behavior in demanding applications.
Control and system integration:
Linear motors are always part of a controlled system. With XENAX® servo controllers, linear motors and actuators are integrated into PLC-based automation via industrial fieldbuses such as EtherCAT, PROFINET, Ethernet/IP, or POWERLINK. This allows linear motors to operate seamlessly within existing machine architectures.
Choosing the right technology:
• Mechanical drives solve basic linear motion tasks
• Linear motors solve precision, speed, and repeatability challenges
• Understanding this difference is essential when evaluating linear motors for sale and selecting the right linear motion technology for your project.
