FAQ: What are current source inverters and voltage source inverters?

The two most common types of inverters are the current source inverter (CSI) and the voltage source inverter (VSI). As their names imply, current source inverters are fed with constant current, while voltage source inverters are fed with constant voltage. Consequently, the output of a CSI drive is adjustable, three-phase AC current, while a VSI ...

SPEED CONTROL OF MOTORS | Wattco

The synchronous speed (S) of a motor is defined as S = 120 (F) ÷ P, where (F) is the incoming line frequency, and (P) is the number of poles in the motor. Since in the United States, the AC line frequency is 60 Hertz at 120 Volts, therefore an AC induction motor with four poles would have a synchronous speed of 1,800 rpm.
