There are two alternate methods depending on whether the motor is single phase or three phase. On a single phase motor, reverse either the start winding coil lead or the run winding coil lead but not both. This action will reverse the motor's rotation. On a three phase motor, interchanging any two of the three coil leads will reverse the motor's rotation.

∙ 8y agoOn a three phase motor reverse any two feed wires that come from the starter. This should be done in the motor junction box. By doing it in the junction box it maintains the three phase colour coding of the building system.

How do you reverse polarity on ac motor?
Reversing polarity is not possible with an ac motor. Some do have wiring that will allow you to change rotation. The type and model of the motor can tell you if it is reversible.
How do you modify the frequency of an AC generator?
You change the speed of rotation.
What end of an ac motor do you look at to determine clockwise or counterclockwise rotation?
The end the shaft comes out.
How do you change the speed of motor without change pole and frequency?
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
Can AC motor work on DC?
use a inverter to change dc to ac or couple it to a ac motor making it a motor generator. Comment: AC motors cannot run on DC since their principle of operation based on induction. There's an exception,however, and thats for Universal Series motor which can run on either AC or DC.

How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
How do you modify the frequency of an AC generator?
You change the speed of rotation.
How do you change an ac motor to a DC motor?
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.

The end the shaft comes out.
High power motor is AC or DC motor?
Either or Both - AC and or DC motor's are both rated by Horsepower / RPM / Torque, DC Motor's are more commonly used where you need to reverse the rotation on the fly (by a button push) - Crane's for example.
How can rotation be change of single phase motor?
With the starting winding disconneted the motor will start up in whichever direction it is spun. To make the starting winding operate the other way, it needs an inductor in series insead of a capacitor. Details depend on the motor, but the reactance of the inductor should match that of the capacitor.
What is the difference between AC machine and DC machine?
ac machines can run only in one direction but dc machines can run in both the directions depending upon the direction of current flow into it. If we change polarity of input supply we can reverse the direction of motion of dc machineCommentThe above answer isn't altogether true, as it's very easy to change the direction of an AC machine. For example, to change the direction of rotation of a three-phase induction motor, the motor controller interchanges two of the three line conductors.The main difference used to be that the speed of DC machines is easier to control, but that is a thing of the past thanks to developments in electronic motor controllers.

Why is the rotation of a fan only in one direction although it is connected to an AC supply?
The direction of the motor is dependent on the way the stator coils are wound.
