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.
What are the ways to reverse motor?
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.
How do you run a motor forward and reverse?
Reversing Magnetic Starters
When the forward contactor is energized, power contacts connect line L1 to T1, line L2 to T2 and line L3 to T3 at the motor. When the reverse contactor is energized, the power contacts connect line L1 to T3, line L2 to T2 and line L3 to T1 at the motor.
How do you reverse an exhaust fan rotation?
You can manually change the direction of a vent fan. If your vent fan does not have a built-in switch to reverse the direction in which the fan’s blades rotate, you can manually require the fan to run in a reverse polarity.
Are all electric motors reversible?
Single Phase Motor Direction Change
Always reverse the wires that lead to the starter winding. Note that most motors, if still labeled with manufacturer instructions, will indicate that they are non-reversible. If this is the case, it’s likely because the wires you would need to access are housed within the motor.
How do you reverse a starter motor?
To reverse the direction of rotation on this starter, all you need to do is to separate the connection of the brush set from the one end of the field coil and the other end of the field coil from the case.
