SPEED CONTROL THREE PHASE INDUCTION MOTOR

slideplayerImage: slideplayerThe speed control of three phase induction motor from stator side are further classified as : V /f controlor frequency control. Changing the number of stator poles. Controlling supply voltage. Adding rheostat in the stator
Stator
The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors or biological rotors. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armatenpediacircuit.

Jun 28, 2016The speed control of 3 phase induction motor depends on various factors like supplied voltage, frequency, number of poles. Speed of 3 phase induction motor needs to varied according to requirement.   Speed controls from stator side as well as rotor side are also.
Speed Control of Induction Motor-Methods
Oct 22, 2019Speed Control of Induction Motor-Methods A three-phase AC induction motor is a constant speed motor as a dc shunt motor. But the speed of DC shunt motor can be changed smoothly simply using rheostats. This maintains the speed regulation and efficiency of DC shunt motor.
3 Phase Induction Motor Speed Controller Circuit
Sep 17, 2019The above explained method of controlling a 3-phase induction motor is actually quite crude since it has no V/Hz control. It simply employs switching the mains ON/OFF at different rates to produce an average power to the motor and control the speed by altering this average AC to the motor.
