If you mean to reverse the direction of a three phase motor, you just switch any 2 leads. switch 1 and 2, or 2 and 3, or 3 and 1.

You switched leads on your 3phase motor and it did not reverse?
Then it is not a three phase motor.
How can a three phase induction motor reverse direction of travel without changing input phase?
by changin the freq usin an IGBT.
Can you reverse the wiring to make the fan reverse?
Yes if it's a dc motor with a permanent magnet field, or if it's a 3-phase ac motor. No if it's a single-phase ac motor or a dc motor with a field winding in series or parallel with the armature. <<>> Single phase AC motors can be reversed by using a reversing switch. Reverse either the start winding or the run winding connections but not both.
How do you use a one phase motor in place of a three phase motor?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
How do you make an AC motor go in forward and reverse?
If it is a three phase motor just interchange any two of the three wires. If it is a single phase motor, which is also known as a split phase induction motor, it has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
You switched leads on your 3phase motor and it did not reverse?
Then it is not a three phase motor.
Why three phase motor run in reverse even if it is not wired to run in reverse direction?
If a three phase motor in running in reverse, then one of the phases is reversed, plain and simple. If the wiring is correct at the motor, perhaps the phase reversal occurred someplace else.
How do you change rotation on a Century AC motor?
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.
To reverse the rotation of a three phase motor you would?
Switch two of the three wires.
Do you change the high leg if your three phase motor is running in reverse?
yes
Why to knw phase sequence?
If you reinstall a three-phase motor with two of the supply conductors interchanged, then the resulting negative phase sequence will cause the motor to run in reverse.
How do you do for phase sequence protection at three phase motor operation?
motor is designed to operate in forward and reverse direction for the purpose of elevator. Phase sequence protection is not required.
How do you reverse the direction of the induction motor?
three-phase motor: Swap the connections of any two phases to the motor.single-phase motor: Usually this can be achieved by reconnecting the starting capacitor from one motor winding to another.Another AnswerAs you have no access to the motor's phases, you must interchange any two of the three line conductors.
Will an ac motor run backwards if polarity is reversed at the outlet?
No, unless it is a three phase motor and you reverse only two of the phases.
How can a three phase induction motor reverse direction of travel without changing input phase?
by changin the freq usin an IGBT.
