Soft starter and frequency inverterSoft starter and frequency inverter. The difference between line starting a motor and ramp starting the motor with a frequency inverter is that the motor/load does not pull the 67 times rated current of the motor, because the motor winding are not saturated with the full EMF produced to get the motor to synchronous speed it is ramped to it.
Choosing between variable frequency drives (VFD) and soft ...09/04/2016 · Motor speed is directly related to its supply voltage frequency. Inherently, a drive or a soft start reduces the inrush current that every motor is subject to when starting across the line. From this perspective, either a drive or a soft start will probably prolong the life of a motor specifically if compared to an across the line starter. This is a general statement and like most general ...
