The difference between VFD and Soft Starter
The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage, not Hertz, and as such the starting torque at 2-3 Hz is next to nothing. The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz, peak (Line) voltage met at 60 Hz.

These are the same functions as used in VFD for continuous duty such as overcurrent, over- and undervoltage, overflux, motor stalling, ground fault protection etc. Some restrictions apply in case of an adjusting transformer between inverter and motor.

Efficiency of wound rotor vs VFD Electric motors
01/09/2005 A ball mill similar to this one had the same problem which was solved by the use of a fluid coupling between the motor and gearbox. The motor is a 4000hp WRIM using an old liquid rheostat. I suspect that the rheostat may be overfilled or not functioning correctly. The push now is to add a fluid coupling for a soft start and leave the rheostat in place. The ball mill should be a fairly constant

Phase Converter vs VFDs, which to use? Wolf Automation
15/11/2016 Many motors are dual rated for 208-240Vac/460Vac. If your motor is, the best approach is to rearrange the motor wires for the 220Vac, 3-phase input. This way you can use either a rotary phase converter (RPC) or a variable frequency drive (VFD) to run the motor off of 220Vac single phase voltage. If the motor is only wound for 460 Vac, 3-phase

Efficiency of wound rotor vs VFD Electric motors
01/09/2005 In the format you have now, the VFD would be far more efficient than the WRIM run by a standard liquid starter system if you are not running at full speed (shorted rotor). At reduced speed, the slip energy coming from the rotor is given up as waste heat. You can get a slip recovery system for the WRIM, and that would in fact make it MORE efficient than the VFD I believe. Running at full speed, the WRIM would be more efficient because of the minor losses in the VFD
