# 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.

Speed Control of Three Phase Induction Motor | Electrical4U
Jul 11, 2019In this method of speed control of three phase induction motor the original sinusoidal mmf wave is modulated by another sinusoidal mmf wave having the different number of poles. Let f 1 (θ) be the original mmf wave of induction motor whose speed is to be controlled. f 2 (θ) be the modulation mmf wave.
Speed Control of Three Phase Induction Motor | Electrical
The speed control of three phase induction motor is done by stator voltage control. The output torque of the three phase induction motor is directly proportional to square of supply voltage for a given slip. The torque – slip characteristics of three phase induction motor is shown in figure A.

Speed Control of Three Phase Induction Motor | ATO
The actual speed of three phase asynchronous motor is given by n=n s (1 - s) =120f /p (1-s). It can be seen from the formula that the speed of 3 phase induction motor can be changed by the means of changing the number of induction motor’s poles "p", the slip "s" and the frequency of power supply"f".
3 Phase Motor Speed Control Methods - your electrical guide
In this speed control method of 3 phase induction motor when the stator voltage is reduced, the air gap flux and the motor torque both will reduce. The speed control is obtained at the cost of reduction of motor torque. In this method, very low starting torque is produced. Therefore, this type of control is not suitable for constant torque loads.
Speed Control of 3 phase Induction Motor - Electrical idea
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 methods of induction motor | electricaleasy
Speed control methods of induction motor. Speed of a DC shunt motor can be varied very easily with good efficiency, but in case of Induction motors, speed reduction is accompanied by a corresponding loss of efficiency and poor power factor. As induction motors are widely being used, their speed control may be required in many applications.
