I have an induction motor running hot and slow in the direction it's supposed to but when I change the lead wires so it runs in the opposite direction it runs as it should. Is there any reason as to why? Could it be a problem with the capacitor? It's a single-phase 200V.
If the motor runs properly in one direction, you should check to make sure you are using the proper connections for forward operation. You should also consider what the load is when the motor is running in each direction. A load such as a fan or centrifugal pump may require less torque when running in reverse. If the motor is running properly when it is lightly loaded, but hot and slow when it is normally loaded, the capacitor or the starting winding may be defective.
