Low-voltage Permanent-magnet synchronous motors

Driving down CO2 emissions is the greatest challenge of our time. That makes reducing energy consumption the order of the day. State-of-the-art speed-controlled electrical drive systems enable us to save maximum energy. One especially energy-efficient solution is permanent-magnet synchronous motors (PM motors).

They are exclusively operated with frequency converters and have substantially higher efficiency levels (>IE3) than asynchronous motors as well as improved partial load performance.

PM motors also have higher performance levels than asynchronous motors of the same size. For example, the magnet wheel precisely following the rotary field enables us to use PM motors on conveyor belts with several drives running synchronously. We can provide all sizes and a wide range of modifications to the standard range of motors.

VEM has positioned itself in the technology of permanent-magnet synchronous motors with its two new lines of

  • permanent-magnet synchronous energy-saving motors
  • permanent-magnet synchronous high-power motors

These products combine the proven design principles of the K21R/WE1R line with this cutting edge technology.
