How does a forward reverse motor work?

How do you make a motor go forward and reverse?

Remove power from the motor. Hook the battery positive wire to the negative terminal and hook the battery negative wire to the positive terminal for a simple DC motor. Install a double pole double throw changeover switch between the battery and the motor. The motor will now have a forward, reverse and an off position.

How can the reverse direction occurs in a forward/reverse starter motor 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.

What are the benefits of forward reverse motor operation circuit?


Forward Reverse starters are widely used due to their relatively low price. There are no limits to the number of times they can be operated. The components require very little space. The starting current is reduced to approximately one-third.

What is the purpose of interlocking in a forward reverse starter?

In the case of reversing starters, interlocking is used to prevent both contactors from being energized at the same time. This would result in two of the three phase lines being shorted together. Interlocking forces one contactor to be de-energized before the other one can be energized.

Why does motor rotate in reverse direction?

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.

What is the method called of preventing a forward reverse motor control circuit from energizing both contactors at the same time which employs two NC contacts?

2. To do this, two contactors for the starter assembly are required-one for the forward direction and one for the reverse direction, ill. 3. A technique called interlocking is used to prevent the contactors from being energized simultaneously or closing together and causing a short circuit.

What would happen if both contactors were energized at the same time?

What can happen if both coils are energized at the same time? The mechanical interlock only allows one armature to pull in which causes the other coil to draw a current of 4 to 10 times higher than it’s pulled-in value. This causes the coil to burn out. … Between the operating coils of the contactors and L2.
