A Ceiling Fan without a Capacitor

Suppose there is no capacitor connected in the ceiling fan motor circuit Fan Capacitor. This way both the starting and running windings are connected in parallel across the single phase AC supply voltage (120V in US & 230V in EU). In this case, when current flows through the winding inductors, it will will produce pulsating magnetic field (from 0 to 180°) instead of rotating magnetic field which is needed for torque and rotation.

Due to to the single phase supply, there is only one revolving flux which rotates in clockwise and then anti-clock wise direction simultaneously. In other words, the direction of motor rotation changes after each of the half cycle (AC sine wave) which leads the rotor to rotate in clock wise and anti-clock wise continuously. According to the double field revolving theory, both torque cancel out each other after a half cycle. The resulting (net) rotating magnetic filed would be zero i.e. zero starting torque. This is why a ceiling fan as well as single phase induction motors are not self starting .
