When power is switched ON to the circuit, pin15 of IC gets reset by C1, rendering a high at its first pin#3 which is the first pinout in the order of sequence for the IC 4017. The proposed washing machine motor agitator controller circuit functioning may be understood as explained below: In this way a washing machine motor is able to rotate in a reverse/forward direction despite of being an AC motor. Next, when the timer relay connects with the winding #2, this winding now becomes the main winding and winding #1 is used like a capacitor start winding for turning the motor in the opposite direction. In the image above, assuming the winding #1 is selected by the timer relay, causes the winding #1 to act like the main motor winding, while winding #2 works like a supporting capacitor start winding, for initiating the motor rotation in a specified direction. How Reverse Forward Rotation is Implemented Therefore, the wiring is implemented in such a way that the each winding works like a main winding as well as capacitor start winding alternately, depending on which winding is selected by the timer relay. Meaning, it has to move anti-clockwise and clockwise alternately. This is because a washing machine motor has to rotate in both ways. Unlike fan motor, the two winding are identical in terms of wire thickness and number of turns.
Understanding Washing Machine Motor Wiringīefore we learn how to make a customized timer controlled washing machine unit, it would be important to learn the basic diagram of a 3 wire washing machine motor.Īs shown in the below diagram, a washing machine motor typically has a couple of identical sets of winding. Kindly let me know how much I should send you by way of bank transfer, which should include your packing and forwarding charges.Į.Rama Murthy., Visakhapatnam., A.P. I should be able to enclose it in a box which is water-proof. This is for working of clothes agitation process. The timing for the operations of relays is 2 secs stop and 5 secs forward and 2secs stop and 3 secs reverse. The unit should have for operating of motor, 2 nos separate relays for running the motor forward and reverse. It could work on 220 volt ac or I can provide 5Volt dc supply thru local power adaptor. What I need is a circuit or your made-item with the specifications as below.
The timer is electrical-mechanical and is working okay. The mechanical/electrical working is good. Of late, its PCB has gone and I am not able to get it locally. I am having old washing machine which is good working till now.
