What rotates in a DC motor?

What causes the rotation of motor?

A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate. This effect can be used to make an electric motor.

How do you rotate a DC motor?

The rotation of the DC motor is accomplished by the force which is developed on a current-carrying conductor in a magnetic field. The current-carrying conductor is connected to the shaft which is able to rotate relative to the stationary body of the DC motor.

What is a rotating part called?

The stationary or outer part is called stator while rotating part from which we get the mechanical output is called rotor.

How does the current in a motor cause the coil to rotate?

Explaining an electric motor

current in the left hand part of the coil causes a downward force, and current in the right hand part of the coil causes an upward force. the coil rotates anticlockwise because of the forces described above.

Why do motors rotate anticlockwise?

It is due to the counter clockwise motion of the motor. The motor rotates in the counter clockwise direction the blades of the fan are attached to the motor hence the blades rotates in the anti clockwise direction. So it is due to the motor rotation the fan rotates in counter clockwise direction.

How do you determine the direction of a DC motor?

You can find out the direction of rotation of a DC motor by facing its commutator end, which usually is the back or rear of the motor, and noting the lead designation.

What will happen if a DC motor will be supplied with AC?

The D.C. motor may run if the A.C. supply is given. If there is a parallel connection, it won’t rotate at all and will start humming, as the positive and negative cycle will cancel out each other.
