The tachometer coil plays a important role in the washing machine system. The sensor is made in the form of a ring on which there are wires. When the motor is in the tacho, due to the magnetic field, voltage appears. The nominal value of the generated voltage is directly related to the speed of the motor - the faster the engine spins, the stronger the voltage that appears in the ring.The tachometer coil allows you to accurately determine the speed of rotation of the washing machine electric motor.
