Capacitor Start and Run Induction Motor

 Capacitor Start and Run Motor

• It consists of starting winding and running winding. 
• The starting winding is connected is in series with capacitor and there is no centrifugal switch it means that the capacitor is permanently connected in the circuit. 

Split Phase Motor and Capacitor Start Induction Run Motor

Split Phase induction motor

• A high resistance is connected in series with the starting winding. 
• The angle between starting current and main current is in the range of 20⁰ to 30⁰.

Capacitor Start Induction Run Motor - Construction & Working

Capacitor Start – Induction run Single Phase Motor

• The phase difference between main winding and starting winding is achieved by introducing an electrolyte capacitor is in series with starting winding. 

Split Phase Motor : Construction & Working

Construction

• The single phase induction motor is not self starting. 
• There is one extra winding placed in the single phase induction motor in order to make the single phase induction motor self starting therefore the single phase induction motor consists of two winding.
