I want to buy inverter driver for a 60000RPM 1.2KW 3PH 220V spindle and I recently knew about VVFD drivers which is variable voltage frequency driver vs the usual VFD which only use variable voltage to driver the motor.
The VVFD controls the the voltage and the frequency of the motor which can lead to a better start up performance by decreasing the startup voltage which lead to decrease the startup current of the motor.
I do not know if this is good for high speed spindles or not
Does anyone have used this type of inverters before to control Chinese spindles?
