# What Causes Dc Motor Rotation?

The rotation of the DC motor can be accomplished with the help of a magnetic field. The conductor is connected to a shaft that rotates relative to the DC motor’s stationary body.

## What causes DC motors to rotate?

When the motor is powered by DC current, a magnetic field is created in the stator, which attracts and repels magnets. There is a chance that the rotor will start rotating. The motor has a commutator that keeps it from rotating.

## Can you explain why a DC motor can rotate in 2 directions?

AC and DC motor turn in either direction. They can be controlled by reversing the leads on the armatures.

## How does a DC motor change direction?

If you want your DC motor to turn in either direction, you need to change the polarity of the applied voltages. The motor’s shaft will turn in the opposite direction when the flow of current is changed.

## How do you control the direction of a DC motor?

The negative and positive leads are connected to the DC motor. The motor will spin in the opposite direction if the terminals are reversed.

## Which component is responsible for rotation of motor in one direction?

In the motor and generator case, the commutator periodically reverses the direction of the current flow through the winding so that it stays in one direction outside the machine.

## What part of a motor rotates?

There is a rotating electrical component. The cylinders are arranged around a pole with the poles facing towards the poles. The AC motor’s shaft has a rotors on it. The word rotating is what inspired the termrotor.

## What factors will affect the rotation of the simple electric motor?

The rotation speed of an electric motor is dependent on two factors. The speed of a motor is determined by the needs of each application and is similar to how the mechanical load is determined.

## How do you know the direction of rotation of a DC motor?

If you look at the back or rear of the motor, you can see the direction of rotation.

## How can you reverse the direction of rotation of a DC motor?

The direction of the current is determined by the voltages. In order to change the direction of rotation, we can simply reverse the voltage, causing the current to flow in the opposite direction, and then drive the motor backwards.

## Which rule determine the direction of current in DC motor?

Which direction the current flows is given by Fleming’s right hand rule. The diagram shows that the right hand is held with the thumb, index finger and middle finger at the same angle.

## Does a DC motor have a rotating magnetic field?

The armature of a DC motor is driven by a rotating magnetic field that is provided by the stator. A simple DC motor uses a set of magnets in the stator and a coil of wire with a current running through it to generate an magnetic field.

## Can a DC motor rotate in both directions?

DC motors can either turn clockwise or counter-clockwise and can be turned on and off at will.

## Does commutator rotate?

A commutator is an electrical switch that reverses the direction of the current between the internal and external circuits. A steady rotating Torque is created by the reversal of the current each half turn.

## How a rotating magnetic field is produced in DC motor?

The rotating magnetic field can be produced by the three phase current of the stator. It is possible to replace it with permanent magnets in a motor. The inner stator has three phases that are 120 apart.
