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.
