In this post you will learn about the 3 wire washing machine motor wiring diagram. As you know that we have two way switch, washing machine timer, bell, light indicator and washing machine motor. First we talk about the parts step by step.  And then we talk about the complete wiring of 3 wire washing machine motor.

Washing Machine Motor Capacitor Wiring Diagram With Timer

Parts of 3 wire washing machine.

Tow way switch : A 2 way switch is used in washing machine wiring to switch the motor in one or 2 direction. I we switch the motor on one side. Its means that the motor will run only in one direction. And if we switch the motor to two direction. The motor will run on both direction. For a small reset the motor will stop and then the motor will start in 2nd direction-. The motor will start clock and anti clock wise by using the washing machine timer.

Washing Machine timer : A timer is used in washing machine, which can be in different shapes and different types. The wiring wire of washing machine can be different color and different number of wires but it's working will always same. In the below 3 wire washing machine motor wiring diagram. A 6 wire timer is used. The timer working is to run the washing machine motor for specific time. By using the timer the motor run clock and anti clock wise. This timer also on the bell when it's complete the washing timer for small time. And then it's switch off the motor and bell.

Bell And Light Indicator : A bell also install the washing machine, this bell switch for small time when the timer complete his time. Also a light indicator Which show on the incoming electric supply.

Washing machine motor : The main part of a washing machine is the motor. The washing machine motor winding is not different from a single phase induction motor but in the motor they both winding is made from the same number of wire gauge. A 4 pole motor is used in a washing machine motor. which have 3 wire. The one wire is common and the 2 other wire is for the capacitor. Also read the below article which help you that how to test the washing machine motor.

Capacitor : A capacitor is used in washing machine to run the washing motor. This capacitor will be a running capacitor. But the value of capacitor can be change according the motor.

Now come to the wiring diagram.
3 wire washing machine motor wiring diagram

In the above 3 wire washing machine motor wiring diagram. The main supply one wire is connected to the washing machine motor common connection point. Same from the wire the light indicator and buzzer wired.

The 2nd wire is goes to the timer black wire. The timer have 5 more wires. In which the blue for buzzer. The green or brown goes to two way switch. A Two way switch have one three output terminals. In which we use only two. The center point will be not use and when switch on center position-. The washing machine will be off.

The timer red wire will connect to two way position point of 2 way switch.  one yellow is connect to one way position point of switch and also the wire goes to the motor. The second yellow wire will connect to the 3rd wire of motor. A running capacitor will connect between yellow wires.

We use three phase motor mostly in many places, in this post you will learn the dol starter wiring diagram 3 phase with complete circuit breaker, contactor and overload relay diagram with step by step. We required some electrical things for three phase motor wiring which are below.

3 phase induction motor
3 core electric cable
Three phase 4 wire system supply (three phase and one neutral)
A circuit breaker
A contactor or starter
A overload relay
and flexible wiring cable for controlling wiring
Normal close push button
Normal open push button

Before we starting talking about the wiring and wiring diagram, first we disuse the above substance . We required 3 core cable, a three core cable is a cable which have internal three electric cable which mostly in red, yellow and blue colors. The three phase 4 wire system supply means that we need 3 phase electric supply and one neutral wire. Note that we use the neutral wire for contactor coil wiring which we called the control wiring.
We also required the circuit breaker which are 3 pole circuit breaker or circuit breaker which can cutoff the 3 electrical connection in same time.

Normal close push button (NC) means that we need a push button which is normally have close electric circuit and when we push it then the button switch off the connection or change to the open electric circuit.
Normal open push button mean that we need a push button which have a open electric circuit in normal state and when we push it then it's change to the close electric circuit.

Dol Starter wiring diagram for three phase motor

To wire a 3 phase motor the first thing to wire is a circuit breaker which is disconnect and connecting point then we will get the supply from circuit breaker and connect supply to contactor or starter and then to overload relay. We connect the circuit breaker, contactor and overload relay in series between electrical supply and motor as shown in below diagram.

dol starter wiring diagram 3 phase
Contactor and Overload Relay Wiring

In a contactor we have a magnetic coil which is use for switching. We have also NC and No point in a contactor which we can use for many connections. In overload relay we have an input and output points. In normally overload points have a close electric circuit between point but whenever the ampere or load is getting high the overload relay switch off or make an open electric circuit between these two point or connection. So we wire the overload relay in series between the contactor coil current.
So for contactor wiring first of all connect the neutral wire to contactor coil first terminal and then connect a wire from the one output terminal of circuit breaker which is opposite or phase current for contactor coil. In this process the control wiring which contactor wiring is also control by breaker and when we switch off the breaker, then contactor will stop working auto.
The control wiring wire which connect from the breaker output terminal will goes to the NC push button and then from NC push to the overload relay and NO push button as shown in above diagram. Then we connect a wire between the 2nd terminal of overload relay and this wire goes to the NO point of contactor and then from NO point wire is goes to the 2nd terminal of contactor coil.
Then in last we connect a were between NO push button switch and contactor 2nd terminal of coil where we connect the phase wire of contactor as shown in above diagram. And this wire connection is called tech current.
Final word
Note that in all wiring use the best quality breaker, push button switches, contactor and overload relay. If your overload relay in not good then it will be not trip and if the overload relay does not trip or not switch the point then it will be case of your motor burn. Note that do all wiring control able from circuit breaker as I shown in above diagram.
Note that always connect the earth wire to motor, and adjust the overload relay ampere by using the adjustment switch.

I spend more than 2 hours on this article writing and designing DOL Starter Wiring Diagram 3 Phase Motor diagram, so if you learn some important things then it's your responsibility to share. Now if you have any question regarding the 3 phase motor wiring diagram then you can ask me in below comment section.

3 phase current transformer wiring diagram for 3 phase load (ampere) testing. As you know that we use the current transformer to measure the current. For testing the current (ampere) running to load we use two types of amp meter. In which one series type which is wired in series between load and supply. And 2nd is a current transformer type which is wired with a current transformer to measure the current. We can wire a current transformer for single phase and also for 3 phase. The current transformer is always used for line ampere testing. For 3 phase system ampere testing every Line have their own current transformer. And these current transformers further connected with 3 ampere meter or one ampere meter and ampere testing selector switch.
