How to Run 3 Phase Motor with 1 Phase Power Supply | 3 Phase Motor to 220v

How to Run 3 phase Motor with 1 Phase power supply:

This diagram shows how to run a 3-phase motor with 1 phase power supply. In this circuit diagram, we need a 3-phase motor and a capacitor. In this circuit diagram first, we input the phase line to the capacitor then from the capacitor to the motor, the capacitor connected to 3 phase motor, then the neutral wire to the motor. If you want more clear details about this circuit please check our youtube video.

Components used to make the 3 phase Motor with 1 phase wiring:

01. Single Phase Motor

Single Phase Motor
Fig 2: Single Phase Motor
Single-Phase Induction Motor is Very Simple in Construction, Economical, Reliable, and Easy to Repair And Maintain. Due to all these advantages, it is widely used in vacuum cleaners, fans, centrifugal pumps, blowers, washing machines, etc. It can run only by supplying 1 phase current through this motor. The main two parts of this motor are Rotor and Stator. Among them, the rotating part is the Rotor and the stationary part is the Stator. Like all induction motors, a single-phase induction motor consists of two main parts, the stator, and the rotor.

02. 5 MFD 400V Capacitor

5 MFD 400V Capacitor
Fig 3: 5 MFD 400V Capacitor
A Run Capacitor is Used in Single-Phase Motors to Maintain a Running Torque on an Auxiliary Coil While The Motor is Toaded. These Capacitors Are Considered Continuous Duty While The Motor is Powered And Will Remain in The Circuit While The Starts Capacitor Drops out. The Run Capacitor, Also Sometimes Called an “A/C Capacitor,” Uses Its Stored Energy to Turn or Run The fan Motor. Without The Run Capacitor, The Fan Cannot Turn. Run Capacitors Are Also Rated by Voltage Classification. The Voltage Classifications are 370V and 440V.
