Two capacitors are used in capacitor start capacitor run motor or two value capacitor motor one for starting purpose and other for running purpose. The electrical schematic diagram on the right shows an illustration of a capacitor start motor. Characteristics of the capacitor start motor. The figure below shows the phasor diagram of the capacitor start capacitor run motor.
Click here to view a capacitor start motor circuit diagram for starting a single phase motor. L1 and l2 are designated as the two connection points representing the two electricity flow path inherent with single phase circuits where a single phase supply voltage is fed to the motors internal circuit. The auxiliary winding is also known as starting winding. The run capacitor is long time rated and is made of oil filled paper. A capacitor start capacitor run induction motor is a single phase motor consists of a stator and a single cage rotor. Wondering how a capacitor can be used to start a single phase motor.
As the motor approaches its rated speed the auxiliary winding and the starting capacitor is disconnected automatically by the centrifugal switch provided on the shaft of the motor.
