SUMMARY
The discussion centers on the power factor (PF) of a motor equipped with a Variable Speed Drive (VSD). A motor with a full load PF of 0.8 and a starting PF of 0.3 will maintain its starting PF at 0.3, regardless of the VSD's datasheet PF of 0.95. The VSD's power input is regulated to 0.95 through a PF correction circuit, but the motor's PF remains unchanged. The VSD must be appropriately rated to manage the reactive VAR of the motor load.
