What Are AC Drives?
AC drives control the speed of either an induction motor or a synchronous motor by adjusting the frequency of the power supplied to the motor.


Benefits of using AC drives for roller grinding applications:

  • Flexible adjustment of the speed of the grinding wheels to control vibration, chatter, and finish
  • Achieving grinding wheel speeds up to 7,000 rev/min
  • Stopping heavy steel tungsten carbide grinding wheels quickly with built-in braking resistor
  • Continuous display of grinder speed-RPM(rev/min) and grinder load-Amp

Vacon X4 drives can be also installed on existing grinders.

We provide programming and installation services and technical support.
