Your question is confusing. Are you asking how to reverse the direction of a three-phase motor? If so, then the answer is that you simply interchange any two of the line conductors. This will cause the naturally-rotating magnetic field in the motor's air gap to reverse direction, causing the rotor to reverse direction.
It can be changed by either reversing field winding connection or rotor winding connection.
That would not be good. It takes reversing 2 of the 3 phases (wires) to get it to run in the other direction.
The phase rotation of motor should be always done from motor side i.e The motor terminal box.
A switch that reverses the direction of the current in a motor is called a forward reverse drum switch. It is a single phase motor that turns from clockwise to counter clockwise.
No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
You would reverse rotation on a 3 phase motor to get it to run backwards. Say I fill up a tank truck from a lake. I turn on my generator. I run the motor in one direction. Then I drive the tank truck and the motor to a different location. Then I turn on my generator. I attach the hose to the motor on tank truck. I throw the switch to make the motor run backwards. I aim the hose at the fire in your house. Aren't you glad that I can make my 3 phase motor run backwards?
by changing the ryb phase altornat e.g. rby ,bry , yrb we change the direction of the induction motor .. . ..
by changin the freq usin an IGBT.
Very often a capacitor IS used in a single-phase motor. It provides a phase-shifted current to the starting winding to ensure that the motor runs in the right direction, e.g. clockwise if that is the requirement.
Connecting Phase A, B and C to the motor leads will make a 3 phase motor run in one direction while interchanging any two will make the motor rotate in the opposite direction.
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
The phase rotation of motor should be always done from motor side i.e The motor terminal box.
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
DC motor: Switch your leads. AC single phase motor: Direction cannot be changed. The motor will run the same direction regardless of how your leads are terminated. AC 3 phase motor: Switch any two leads.
because its possible only where pole changing arrangements are given and pole changed motor draws more current then its actual pole which damages its windings.
