Suppose, you are enjoying a holiday at your home. All enjoyments go to dogs while looking at the dirty clothes. You decided to wash the clothes. You take the clothes and put them into the washing machine. As an electrical engineer, a thought hit upon your mind how to draw a 3 wire washing machine wiring diagram? This article is going to deliver this information. Let’s discuss.
What is Washing Machine?
A washing machine is a motor-based device which washes our clothes. Once upon a time, we wash our clothes by assigning a washerman. But nowadays technology is too developed. All manual systems are being erased and automatic and artificial intelligence-based technology is welcoming us. An electrical motor is the core part of a washing machine. Other types of equipment are also here. Let’s introduce them.
The Essential Parts of Washing Machine
With a view to drawing 3 wire washing machine diagrams, we have to know the essential parts of the washing machine. They are:
- Two-way switch
- Washing machine timer
- Bell and light indicator
- Washing machine motor
We can identify a tree by observing its fruit. Similarly, the two-way switch is also named by observing its activity. We can switch up a motor in two directions by utilizing a two-way switch.
In this circumstances, the motor will rotate in two directions. Once it rotates clockwise and again it will rotate in the anticlockwise direction. But for how much time does it rotate in one direction?
Here, we require a device that will fix up this time. What is that device? It’s Mr. Timer. Now, I am going to discuss timer.
In 3 wire washing machine wiring diagram, you can see a six-wire-based timer that counts the time of rotation of the motor in a single direction. The direction may clockwise or anti-clockwise. But it will not rotate for an infinite time.
Bell And Light Indicator:
You can connect an alarm or bell circuit is connected to the washing machine. It beeps when the rotation of the motor is completed. There is also a light indicator that ensures the power supply in the washing machine. We also see light indicators in multiplug or electrical panels.
3 wire washing machine motor:
The electrical motor is the heart of the washing machine. It is mentioning the fact that manufacturers use a 4 pole induction motor in the washing machine. Nowadays they use the universal motor in washing machines. This motor contains 3 wires. A single-phase capacitor is connected to the motor for creating starting torque.
We use a running capacitor in a washing machine to start up the motor. This capacitor size will be dependent on the power of the motor. For a clear conception of using capacitors, you may visit this article 3 Wire Capacitor Diagram For Ceiling Fan

In the above 3 wire washing machine wiring diagram, we can see the main 120volt AC supply wire is connected to the washing machine motor common connection point. A running capacitor rated 10 uF is connected with this motor. A two-way SPDT switch is also connected with this universal motor.
How Does a Washing Machine Work?
Now, a vital question is how the washing machine works? Actually unhygienic elements exist in the fiber molecule of clothes. That’s why we utilize detergent mixture water with a view to washing clothes. The washing machine provides the automatic mechanical potential to wash up the clothes with detergent mixture water indeed. In a word, The detergent-infused water acts as an enemy of dirt.
A universal motor produces mechanical energy in a washing machine. Manufacturers use universal motors not only in washing machines but also in other kinds of home appliances. A universal motor is a modified form of a DC motor.
How does Universal Motor Work in Washing Machine?
If we connect the AC single-phase supply to a DC series motor, then the motor will begin to rotate. When a positive half cycle arrives, the armature series winding will consume the current.
Now during the next negative half-cycle, the supply current direction will be reversed in the armature winding. After reverse the direction of the current the motor gets the potential to create torque. Finally, it begins to rotate.
