3 phase Motor on Single Phase:

This Diagram shows how to run a 3-phase motor on a single-phase supply. In this circuit diagram, we use a 3-phase motor, a 50 MFD capacitor, a magnetic contactor, an NC switch ( Normal Close ), and a NO switch ( Normal Open ).  First, we input the power line to the magnetic contactor and NC switch, then from the NC switch to the NO switch, then connect the magnetic contactor, switch, motor, and capacitor as in the image. If you want to know more about this circuit and want to see the connection of this circuit please check our youtube video link below.

Components used to make the 3-phase Motor on Single Phase:

01. 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.

02. 50 MFD Capacitor:

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 the 50 MFD Capacitor indeed the value of the run Capacitor can affect Motor Speed.

03. 3-Phase Motor:

A Three-Phase electric motor uses a 3-Phase Power Supply to Convert Electric Energy into Mechanical Energy. It contains four Wires (Three hot Wires and one Neutral Wire) and Uses 3 Alternating Currents of the Same Frequency. Since it Generates a Rotating Magnetic Field, it does not need a Capacitor for the Startup. Some Three-Phase Motors are Reversible, Which Means they can serve as Generators by Turning Mechanical Energy into Electrical Energy.

04. 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.

I05. 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.
