The capacitor-start capacitor-run induction motor consists of a squirrel cage rotor and its stator has two windings, viz. the starting or auxiliary winding and the main or running winding.

It consists of a stator with two sets of windings placed 90 electrical degrees apart - the main winding and auxiliary or starting winding. A capacitor is connected in series with the starting winding.
After the motor reaches to 75% of the full-load speed the switch is opened and the only capacitor C 1 is present in the auxiliary winding circuit. In this way, best starting performance with high capacitance and best running performance (best torque condition) with low capacitance is achieved.
The Phasor Diagram of the Capacitor Start motor is shown below: I M is the current in the main winding which is lagging the auxiliary current I A by 90 degrees as shown in the phasor diagram above. Thus, a single-phase supply current is split into two phases.
Run capacitor C 1 and auxiliary winding can be designed in such a way that they provide balanced two-phase field. The balanced two-phase field avoids the backward rotating field and improves the power factor and efficiency of the motor. The torque-speed characteristics of two-value capacitor run motor are shown in figure (2).
From the circuit diagram, it is clear that the starting capacitor (C) is connected in series with the starting winding. The function of this starting capacitor is to create a phase difference between the currents of starting winding and running winding.
