Washing machine motor brushes are the left and right carbon brushes the only component in a washing machine motor that can wear down after long periods of timebut can also be used to connect our motor using the diagram in the next step without using a controllerbut this procedure should only be unsed to test the universal motor if is working or notbecause starting at maximum speed for long. The direction of rotation can be controlled as shown in fig2.
Washing Machine Motor Speed Control
Washing machine motor controller circuit diagram. They are basically the same as a dimmer switch. Electronic washing machine control circuit provides all the facilities provided by reputed companies and even more. When switch s1 is in position a coil l1 of the motor receives the current directly whereas coil l2 receives the current with a phase shift due to capacitor c. Description of motor controller circuit for washing machine. They are only regulating the voltage not the speed. The period for which motor should rotate and stop the motion of motor after every 10 seconds for a 3 second interval and reverse the direction of rotation.
In the back side of the motor you can find the tacho coil with we will not use but is good to know if you need to replace it with a spare parts if this one is gonna breakby the name i am guessing that with this component the washing machine controller is sensing the rpm of the motor and it regulates the speed accourding to the faze of the programm. The single phase motor work along with a master timer and a spin direction controller so as to calculate the washing time ie. These are scr regulators and use triacs. Circuit diagram of washing machine motor controller. Washing machine motor controller circuit fig1. The circuit has a timer circuit which can be set to any duration from 0 to 15 minutes and can be extended to any length of time by merely changing a capacitor.
Figure 1 depicts the overall figure of the project. The circuit has switching circuits which run the impeller in one direction for 25 seconds and stop the motor for five.
