This is an AC motor brake circuit. This circuit is used to make the motor stop/decelerate faster  (braking), more than just cutting the power of the ac power tool motor.  Here is the schematic diagram of the circuit: The braking mechanism is done by a diode and switch S1. When this switch is on, the motor will be fed by […]

Closed loop or servo system has the ability to stabilize the controlled plant at a specified operating condition. The plant, the controlled sub-system, can be any form of controllable system. In motor control system, the plant is off course a motor. The basic principle of automatic control mechanism in motor control is by monitoring the real speed of the motor, […]

A shaded-pole AC induction motor is one of type of AC induction motor that does not have start winding but has only one main winding. This type usually called “disposable motors because it better replace than repair. Besides cheap, the other advantages of this type are the speed can be adjusted by through a multi-tap winding or varying voltage, simple […]

An induction motor is one of type of AC motor that is supplied by means of electromagnetic induction. This motor has some advantages like has high efficiency and can be used for lower full-load currents. However, this motor is expensive because this motor use centrifugal switch and run and start capacitors. The applications that uses this motor is air compressors, […]
