What Is A VFD Drive Inverter?
A VFD (Variable Frequency Drive) inverter controls a spindle motor's rotational speed by varying the frequency of electrical power supplied to it, enabling precise RPM control across a wide range. TriQuench India supplies VFDs matched to spindle motor power ratings from 0.75 kW to 15 kW.

Frequently Asked Questions — VFD Drive Inverter
What does a VFD do for a CNC spindle motor?
A VFD regulates the spindle's RPM by adjusting output frequency, while also providing overcurrent protection and stable torque delivery for 3-phase high-speed motors.
How do I match a VFD to my spindle motor?
Match the VFD's rated power (kW) and voltage output to your spindle motor's nameplate specifications — an undersized VFD can't deliver stable torque at higher RPMs.
