A feedback control system can be made involving microcontroller 8051, inverter(gating circuit), power processing unit, induction motor whose speed is measured via digital tachometer. The microcontroller will act as a Frequency Counter, Comparator and PID Controller. The output from tachometer(digital) will be given to microcontroller which will compare this to the reference signal and then pass the control signal to gating circuit.The power unit's output will be given to motor.
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method

Single phase Induction motor
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
Could be a single phase induction motor of 20-40 watts.
