Speed control of induction machine
WebFrom the above equation, the speed of the motor depends on supply voltage (V), Flux (Φ), and Armature resistance (Ra). Therefore, the speed of a DC motor can be varied, changed and controlled by changing; Terminal voltage “V” (AKA Applied Voltage Control Method). External resistance with armature resistance Ra (AKA Rheostatic Control Method).

WebMay 7, 2024 · Volts/Hz Control Remembering that induction machines generally tend to operate at relatively low per unit slip, we might conclude that one way of building an adjustable speed drive would be to supply an induction motor with adjustable stator … WebThe AC induction motor is essentially a constant speed device. The speed of the rotating magnetic field is referred to as synchronous speed. 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.
