# Why does a DC motor spin?

Contents

When the motor is powered by DC current, a magnetic field is created within the stator, attracting and repelling the magnets on the rotor. This causes the rotor to start rotating. To keep the rotor rotating, the motor has a commutator.

## How does a DC motor spin?

In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate. A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil.

## What causes a motor to spin?

Electric motors use magnets to convert electricity into motion. … The attractive and repulsive forces of the permanent magnets around it make the electromagnet spin. This circular motion is then used to power anything from a fan to an electric car.

## How does a DC motor work simple explanation?

Electric motors turn electricity into motion by exploiting electromagnetic induction. The motor features a permanent horseshoe magnet (called the stator because it’s fixed in place) and an turning coil of wire called an armature (or rotor, because it rotates). …

## How can a motor spin fast?

One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.

## How can a motor be made more powerful?

Motor can be made more powerful by winding the coil on a soft iron core of by increasing the number of turns of the coil.

## What are the advantages of DC motor?

Good speed control

DC motors offer highly controllable speed. By changing the armature or field voltage it’s possible to achieve wide speed variation and with this level of controllability, DC motors offer the precision required by a wide range of industry applications.

## What is the main function of a DC motor?

A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation.
