QB / QS Series

Our QB / QS (QUANTUM) synchronous servo motors are 3-phase brushless motors for demanding servo applications in industrial and automation field requiring low power and operation from low voltages (up to 300VDC).

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
