The starter winding is typically composed of a smaller wire, resulting in a bundle with less magnetic strength than the main winding. Each winding is comprised of a bundle of copper wires that carry electric currents and produce magnetic fields. For a quick explanation on how AC motors operate, checkout our Tech Tip Video.įor this example, we will use an AC motor that has two copper windings within the stator-a main winding and a starter/auxiliary winding. Understanding AC Motor Rotationīefore we discuss how to reverse an AC motor, we must first understand how the induction motor rotates. (Note, not all AC motors have the ability to be reversed, but all of Groschopp’s AC motors can be). This is as easy as unhooking and re-crimping the designated wires. Thus, you can often reverse AC motors by switching the wire connections. The DOL starter comprises of an MCCB or circuit breaker, contactor and an overload relay for protection.Motor rotation is essentially created by the manipulation of wires and magnetic fields.
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.ĭOL Starter Wiring Diagram A direct online starter consits of two buttons, a GREEN button for starting and a RED for stopping purpose of the motor. Similarly, you may ask, how do you reverse a starter motor? And this can be accomplished by reversing the polarity of the starter winding.
To reverse it, we need to change the direction of the rotating magnetic field produced by the main and starter windings. How do you make a single phase motor go forward and reverse? Once started, a single phase induction motor will happily run in either direction. The Reversing Starter is a special type of push button starter wherein addition to starting/ stopping of motors the director of rotation of a three phase induction motor can be done by inter changing the connection of any two terminals of the supplies which is done through two separate contactors, one for forward and. When stop push button (S1) is pressed it will stop the motor when it is running in the reverse direction and when push button (S2) pressed it will stop the motor when it is running in the forward direction.Īlso know, what is forward/reverse starter? This same action implies on the reverse starting.
