The key characteristics of the motors are as follows:

  • 3-phase, permanent magnet brushless servomotors
  • 6-pole
  • High dynamic response
  • Holding torque from 0.1 to 20Nm
  • Supply voltage from 24 to 400Vdc (various winding options)
  • Available as frameless (preferred version) or housed
  • Special laminations for reduced iron losses at high speed operation (QS models), no change in dimensions
  • Custom windings and mechanical modifications possible
