Customer ServiceThe capacitor C is permanently connected in the circuit both at starting and running conditions. Since the capacitor C is always in the starting, this type of motor has no starting switch. The auxiliary winding is always in the circuit; therefore, this motor operates in the same way as a balanced two-phase motor.
The starting torque of a capacitor start induction motor, ranges between 3 to 4.5 times the full-load torque which is twice that of split phase induction motor. A centrifugal switch is connected in series with auxiliary winding and capacitor. The purpose of this switch is to disconnect the capacitor when motor attains 75% of full-load speed.
The physical construction of a capacitor-motor can be done by connecting a capacitor unit near the motor. The shape of the capacitor-motor is a cylindrical hump.
As the motor approaches synchronous speed, the capacitor Cs is disconnected by a centrifugal switch SC. The capacitor CR is permanently connected to the circuit. Since the capacitor Cs is used only at starting and the other CR for continuous running, this motor is also called a capacitor-start capacitor-run motor. 4.
This is a modified split-phase motor with a capacitor in series with the start winding to provide a start “boost.” Like the split-phase motor, the capacitor start motor also has a centrifugal switch which disconnects the start winding and the capacitor when the motor reaches about 75% of the rated speed.
Run capacitors are used in some single-phase AC motors to strengthen the auxiliary coil so that a rotating magnetic field can be formed when the motor is running. Run capacitors work continuously once the motor is activated. These capacitors are generally polypropylene film capacitors.
