To reverse rotation on a single phase capacitor start motor, you will need to reverse the polarity of the starter winding. This will cause the magnetic field to change directions, and the motor will follow. In order to achieve this, you can swap the connections on either end of the winding. Always reverse the wires that lead to the starter winding.
What I know is that the capacitor provides a phase change in the second winding so it can apply force when the motor is running. So we have 2 wires to the motor, and they are in different phases, which makes the magnetic fields have different directions at different times. But: how can my fan spin the other direction as well?
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:
Swap the connections of the start winding and run winding. Ensure that you correctly identify the two windings before proceeding. Refer to the motor’s user manual or wiring diagram to verify the correct connections for reversing the rotation. If reversing the wiring connections doesn’t solve the issue, it’s time to examine the motor’s capacitor.
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.
To reverse the direction of a single-phase motor, especially a capacitor-start induction motor, use the following steps: To avoid electrical dangers, always disconnect the motor from the power supply first. Locate the wires that link to the motor’s starter winding.

how do you reverse rotation direction on grinder
Re: how do you reverse rotation direction on grinder Thomas, If it is already rotating clockwise, That is the what you want. Most bench griders run counterclockwise. You want the knife to be pulled away from you instead of toward you like the counterclockwise. Some motors can not be rewired to run backwards sort of speaking.
