How do you reverse the direction of a DC motor?

How to Reverse Your DC Motor. Your DC motor can be configured to turn in either direction by simply inverting the polarity of the applied voltage. The change in the flow of current switches the direction of the spinning force, causing the motor’s shaft to begin turning in the opposite direction.

How do you reverse the rotation of a DC motor?

The direction of rotation of a dc motor can be reversed:

  1. By reversing the connections of both armature and the field windings with the supply.
  2. By reducing the field flux.
  3. By reversing the connections of either the armature or the field winding connection with the supply.

How do you reverse the direction of a motor in a circuit?

The direction that a three-phase motor spins is determined by the phase sequence of the voltage impressed upon it. To reverse the direction of the motor we simple reverse the phase sequence by switching any to line leads. In electrical terms, refers to a connection where current has only one path to flow.

How can the speed of a DC motor be controlled?

Thus, the speed of a DC motor can control in three ways: By varying the flux, and by varying the current through field winding. By varying the armature voltage, and the armature resistance. Through the supply voltage.

What happens if you reverse the polarity on a DC motor?

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. On the other hand, you can also reverse the field leads but this is risky: doing so can affect the stability of your DC motor.

How do you change the polarity of a DC motor?

Of course, the direction of current is controlled by the polarity of the voltage. So in order to change the direction of rotation, we can simply reverse the voltage, causing the current to flow in the opposite direction, changing the force by 180 degrees and the motor to be driven ‘backwards’.

How do you determine the polarity of a DC motor?

1 Answer. DC motors can usually run with either polarity but direction of rotation will be reversed. Read the data sheet or the label on the motor if you need to be sure it will turn the right direction on start. The armature draws more current than the field so needs a heavier wire.
