6 FAQs about [How to rotate the capacitor rotor]
How do rotor plates affect the capacitance of a stator?
The stator is a stationary part and rotor rotates by the movement of a movable shaft. The rotor plates when moved into the slots of stator, they come close to form plates of a capacitor. When the rotor plates sit completely in the slots of the stator then the capacitance value is maximum and when they don’t, the capacitance value is minimum.
How does a motor rotate?
When the motor is initially powered, the capacitor provides a phase shift in the voltage, creating a rotating magnetic field. This rotating magnetic field interacts with the stationary windings in the motor, causing it to start rotating. Depending on the specific design and configuration of the motor, the rotation direction may be reversible.
How does a rotor reverse a motor?
The rotor tries to follow it, causing it to spin. Reversing the motor is simply a matter of moving the power connection so that the other winding is directly on AC. Essentially, moving one side of the power connection from (A) to (B), causing winding (O) to be the main winding and winding (M) to be the phase shifted one.
How to change the rotation direction of a single-phase motor?
The rotation direction of a single-phase motor can be changed by modifying the wiring connections. To rotate the motor clockwise, you need to swap the positions of the starting winding and the running winding and also reverse the direction of the start capacitor. To do this, follow the steps below:
What happens if a rotor is stationary?

How can a capacitor run induction motor be reversed?
The direction of rotation in a single-phase capacitor run induction motor can be reversed by changing the direction of the rotating magnetic field produced by the main and starter winding or auxiliary winding. This can be accomplished by reversing the polarity of the starter or auxiliary winding.
