380V Mechanical Adjustable Variable Frequency Drives for Grinders

Grinders are used for cutting or shaping metal parts and providing the properly finished surface. Drives or Motion products are used to maintain constant grinder wheel speed during all phases of the process.

Application Challenges

Speed
Maintain constant grinding surface speed Efficiency
Grind at optimal efficiency while doing heavy or light grinding Electronic Gearing
Follow an external encoder to synchronize conveyor with other sections of the process Adjust torque to optimal performance as grinding stone dulls or clogs

Tips:

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
