Forget about it.
I would not recommend doing it. Unless you are very careful.

Switching the wires as you would do with DC motors is not advisable. Check reference s first.

If it is a normal AC 110 volt motor, reversing the leads should make it run the other way.

Currently you have a "hot" and a "neutral" wire going to the motor.

Switch the wires so that the "hot" goes where the "neutral" used to go and vice-a-versa. You don't need to identify which is which, just switch them.

BE CAREFUL. Some appliances have a chasis ground that is integral with the neutral. If you reverse the leads to that kind of appliance then it is possible to cause a short to ground which will trip whatever breaker you hopefully have, or it may just charge the chasis so that you could be electricuted by touching the appliance and some ground like a water pipe.

You don't say what kind of motor. As others have said, do not reverse hot and neutral. From any devices point of view, the hot and neutral are the same (it is AC) and reversing them does nothing. From a safety point of view, the neutral is grounded so there is a difference. Others are wrong saying the case would be connected to the neutral. An appliance either has a ground connection that the case is connected to, or the case is double insulated so it is considered safe without a ground connection. The case is floating (not connected to anything electrically).

Some (most?) single phase A/C motors can be reversed, but it depends on the type of motor. Think about a drill or a ceiling fan. They can run either direction. Small appliances typically have universal motors. Ceiling fans have induction motors (bigger but quieter). What kind of motor are you talking about? There are also many types of single phase induction motors.

First read Seductives answer. I assume this is an single phase AC (alternating current) motor. You said 110 Volts, that is not a typical DC (direct current) voltage. DO NOT reverse the neutral and hot leads,on a single phase AC motor.
1. It will not cause the motor to run in reverse
2. your typical Single phase AC motor is designed with a bias from the rotor to the stator to give starting torque in (ONLY) one direction. (Some use a Capacitor to phase shift the current during starting to add to this starting torque)

My advice is "JUST DON'T DO IT"

Three phase AC motors will reverse if you swap any two phase leads to the motor (not , however, the ground,neutral or star lead)

IF.... this is a DC motor.....reversing the POS(+) and NEG ( -) leads will reverse the rotational direction of the motor.

Hope this helps.........

no count number style if that's a classic AC 100 ten volt motor, reversing the leads would favor to make it run any opposite direction. on the on the spot you've a "warmth" and a "impartial" twine going to the motor. replace the wires in simple terms so the "warmth" is going the position the "impartial" used to bypass and vice-a-versa. you do not would favor to p.c.. out that is which, purely replace them. be careful. some domicile kit have a chasis floor that is crucial with the impartial. in case you opposite the leads to that style of kit then that is achievable to reason a speedy to floor which will vacation inspite of breaker you hopefully have, or it would want to value the chasis so as that you may want to probably be electricuted by using touching the employing and some floor like a water pipe.

switch the red and black wire from leading from the transformer to the motor. This would swap the polarity.

reverse the polarity
