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. [DOC]Section 23 05 11 - COMMON WORK RESULTS FOR HVAC · Web viewUse synchronous belt drives only on equipment controlled by soft starters or variable frequency drive motor controllers without a bypass contactor. Use V-belt drives on all other applications. Alignment of V-Belt Drives:Set driving and driven shafts parallel and align so
