Motors of the series DUM 4 are highly dynamic permanent-field synchronous servo motors.
Thanks to their magnet geometry, they are characterized by their particularly high pulse torque. The motors are UL/CSA approved and therefore usable world-wide.
A multitude of options allow optimal customization.

Preferred application areas:

  • Wood tool machines
  • Textil machines
  • Tooling machines
  • General engineering
  • Special engineering
Technical Data
  • Rated torque: 0.32 .. 275 Nm
  • Highly dynamic 6-pole permanent-field synchronous motors
