Three phase motor with start and stop wiring:
This diagram shows how to make a Three-phase motor with start and stop wiring. In this circuit, we use a DP MCB ( Double Pole Minature Circuit Breaker ), a magnetic contactor, a single-phase motor, and a capacitor. First, we need to connect the DP MCB with the power source, then connect the magnetic contactor with the DP MCB, then connect the NC and NO switch with the contactor, then connect the capacitor and the motor with the contactor.

Components used to make the Three phase motor with start and stop wiring:
01. DP MCB:
DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.
02. Magnetic Contactor:
A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.
03. NC Switch:
An NC (Normally Closed) Push Button is a Push Button That, In Its Default State, Makes Electrical Contact With The Circuit. An NC (Normally Closed) Push Button is a Push Button that, in its Default State, Makes electrical Contact With the Circuit. When The Button Is Pressed Down, The Switch no Longer Makes Electrical Contact And The Circuit is Now Open. When The Button is Not Pressed, Electricity Can Flow, But When it is Pressed The Circuit is Broken. This type Of Switch is Also known As a Normally Closed (NC) Switch.
04. NO Switch:
NO (Normally Open) Terms Refer to a Type of Dry Contact or Wet Contact. A ‘Push to Make’ Switch Allows Electricity to flow Between its two contacts when held in. When the button is released, the Circuit is broken. This type of Switch has also known as A Normally Open (NO) Switch. As its name implies, a Normally Open (NO) Switch Contact or “a Contact” is a Switch. Put very simply, a Normally Open Sensor will have no Current When in a Normal State But When it Enters an Alarm State it will have +5V applied to the Circuit.
05. Capacitor:
Motor Starting Capacitors are used during the Motor Startup Phase and are Disconnected From the Circuit once the Rotor Reaches a Predetermined Speed, Which is Usually about 75% of the Maximum Speed for that Motor type. These Capacitors Usually Have Capacitance Values Of Over 70 UF. The Starting capacitor creates a Current-to-Voltage lag in the Separate start Windings of the Motor. Starting Capacitors are Wired into The Auxiliary Winding Circuit of the Motor and are Disconnected from the main winding circuit by the Centrifugal Switch once the Motor has Reached a Predetermined Speed.
06. Single Phase Motor:
A Single-Phase Motor is an Electrically-Powered Rotary Machine That Can Turn Electric Energy into Mechanical Energy. It Works by Using a Single-Phase Power Supply. Single-phase Motors Are Used in Equipment And Machines That Are Smaller in Size And Require Lower Horsepower. This Includes Equipment Such As Refrigerators, Pumps, Compressors, Fans, and Portable Drills. Single-Phase Motors Have a Similar Construction to The Three-Phase Motor, Including an AC Winding That is Placed on The Stator And Short-Circuited Conductors That are Placed in a Cylindrical Rotor.
