How to wire A single Phase motor

 

     

 

 

 

A single-phase induction motor is composed of a single-phase winding located on the Stator and a cage windings on the rotor. When a single-phase power supply is applied to the stator winding, it generates a pulsating magnetic field. Due to inertia, the rotor remains stationary in this pulsating field.The structure of the single phase induction motor determines that the reverse rotation is generally completed by hardware.

 Why there is a capacitor? 

1.In the original setup, both the main coil and the auxiliary coil receive power simultaneously, creating equal electromagnetic forces that oppose each other, preventing the rotor from turning.

 2. To make the magnetic field force rotate, it can be achieved by passing alternating currents of different phase sequencing the main coil and the auxiliary coil.

Forward connection

⚠️Wear a safety gear before you proceed! 

⚠️Use 4mm² cable size 

Note: You can use DP switch to control the motor ON/OFF direct online.(40A recommended)

 Note: it's not advised to connect yourself if you are not experienced. 

• Now, link U1 to V1
• Then link U1 to V2

Your Line in (Power supply) (L) (N) to (V1) (V2) or (U1) (U2) 

Reverse connection 

Now you've to change the link bars directions

• U1 to U2
• V1 to V2
• Line in (Power supply) to L (U1)  N(V1).
