Capacitor Start Induction Motor – Working & Applications
A Capacitor Start Induction Motor is a single phase motor consists of a stator and a single-cage rotor. The stator has two windings i.e. main winding and an auxiliary winding. The auxiliary winding is also known as starting winding. In construction, these two windings are placed 90° apart in space. The Capacitor Start Induction Motor ... <a …
What is a capacitor used for in an electric motor?
Running a motor without a capacitor may be possible in some cases, particularly for small motors or where the motor is designed for direct-on-line starting. However, for single-phase induction motors, especially those used in appliances and tools, a capacitor is typically required to ensure reliable starting torque and smooth operation.
Capacitor Start Induction Motor
Characteristics of the Capacitor Start Motor The capacitor starts motor develops a much higher starting torque of about 3 to 4.5 times the full load torque. To obtain a high starting torque, the two conditions are essential. They are as follows:-The Starting capacitor
