Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. … Electric Motors have an array of applications.
How does a motor spin?
Inside an electric motor, permanent magnets are set onto a ring surrounding a coil of wire. When the appliance’s switch is flicked on, electrons flow through the wire, turning it into an electromagnet. The attractive and repulsive forces of the permanent magnets around it make the electromagnet spin.
What does a motor do?
A motor converts electrical energy into mechanical energy.
What is the basic principle of an electric motor?
The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.
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 does electricity power a motor?
Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.
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.
How does a DC motor start rotation?
The armature, which is the rotating part, is a simple coil. The armature is connected to a DC power source through a pair of commutator rings. When the current flows through the coil an electromagnetic force is induced on it according to the Lorentz law, so the coil will start to rotate.
Why are motors important?
Electric motors impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and multitudes of other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy.

Does Flat Iron uses an electric motor?
Flat irons are constructed with heating elements that become hot when the flat iron is plugged into an electrical source and the power switched on. Some flat irons are battery powered, in which case they heat up simply by being switched on.
