AC Motor Drives

AC motor drives are also called variable frequency drives (VFD). Sometimes they are known as inverters, adjustable frequency drives (AFD), variable-voltage / variable-frequency (VVVF) drives, variable speed drives, AC drives, and micro drives.

Variable Frequency Drives

We sell variable frequency drives compatible with 3 phase spindle motors, commonly in use by Motionmaster, DMS and similar CNC machinery. They control AC motor speed and torque of the cnc spindle motor by varying motor input frequency and voltage. Our most popular variable frequency drive inverter series are Delta VFD-C2000 Series and Yaskawa V1000 drives. These are the two most likely to replace any CNC spindle VFD you might need. Contact our sales team if you would like assistance cross-referencing replacement AC motor drives.
