3 phase motor to single phase supply:

This diagram shows how to make a connection between 3 phase motor and to single-phase supply. In This circuit, we use a single-phase energy meter, a DP MCB ( Double Pole Miniature Circuit Breaker ), a magnetic contactor, a capacitor, an NO Switch( Normal Open switch ), and an NC Switch ( Normal Close Switch ). First, we need to input power to the single-phase energy meter, then we need to input power to DP MCB, then input power ( phase and neutral line ) to the magnetic contactor, then input connection to NC and NO switch, after that connect the capacitor and motor with magnetic contactor. Now this circuit is ready for use if you want to know more about this circuit please check our youtube video below the post.

Components used to make the 3 phase motor to single phase supply:

A Single-Phase Energy Meter is a sort of Watt-Hour meter. It consists of two Electromagnets. Single-Phase Energy Meter is also Popularly known as a watt-hour meter. One Magnet is called the shunt magnet Ml which is Mounted with a Pressure coil. The Pressure coil is a long coil Made of fine Copper wire which is connected across the Supply line. Single-phase energy meters are suitable for measuring single-phase AC current frequencies of 50/60 Hz, which are used for fixed indoor installations.

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.

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.

This 50 MFD Capacitor Electric motor Capacitor article Series Explains the Selection, Testing, installation, & use of Electric motor Starter Start and run Capacitors used on Various Electric Motors Found in or at Buildings such as air Conditioner Compressors, fan Motors, and some Good Pumps. An Electric motor’s run Capacitor (50 MFD Capacitor) Remains active after the Starting cap has Dropped from the circuit (as the motor has its proper speed), and 50 MFD Capacitor indeed the value of the run Capacitor can affect Motor Speed.
