What are the two ways to reverse the direction of a motor?
DC motors, like AC motors, can be configured to turn in either direction. Their direction can be easily controlled by inverting the polarity of the applied armature voltage by reversing the armature leads. This works with shunt, series, and compound wound DC motors.
Can you reverse the direction of an AC motor?
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. This easy switching of wires works because the polarity of the magnetic field is reversed, thus reversing the motor.
Can a simple electric motor run in reverse?
Switching the polarity of the input voltage will cause a simple DC motor to run in the reverse direction. Switching the starter winding leads will cause a single phase AC motor to run in reverse. A 3 phase motor will run in reverse by switching one leg of the input power.
What happens when a DC motor is reversed?
The motor with run on power up in one direction and when the control signal is applied it will reverse direction. Please bear in mind the higher current drawn when the motor is reversed without first being stopped and ensure that it does not exceed the rating quoted for the board.
Do you have to reverse the winding of an electric motor?
To change/reverse that direction, you need to reverse the polarity of the starting winding. You can find directions from the manufacturer on how to do that for your specific — unless your motor is labeled non-reversible.
Is there a way to reverse the magnetic field on an electric motor?
This happens to be an easy fix: all you need to do is swap any two the power leads to flip/reverse the magnetic field, and the most common practice is to switch lines 1 and 3. Once this is done, the motor should be running in the right direction.
Can a single phase AC motor be reversed?
However, single-phase AC induction motors are a bit more complicated to fix if they are running in the wrong direction. To change/reverse that direction, you need to reverse the polarity of the starting winding. You can find directions from the manufacturer on how to do that for your specific — unless your motor is labeled non-reversible.
