An Electric Motor

Anything that turns electricity into motion, electrical energy into mechanical energy, is called anelectric motor.

Working of Electric Motor

Electric motors work on the principles of electromagnetism. When charges are still, they create electric fields. But when charges are in motion, they produce magnetic fields. Current in a wire, for example, produces its own magnetic field. This is what happens in an electric motor to create movement.

An electric motor contains a coil of wire (sometimes called a solenoid), that creates a magnetic field when electricity flows through it. This is as a whole is known as an electromagnet. An Electromagnet - How the Magnetic Field is Created

Because of this, the wire feels a big force. And this force causes the loop of wire to move and thus electrical energy has been changed into movement.

If we look at the diagram of the loop of wire inside the magnetic field, we'll see that sides B and D have currents flowing in opposite directions. Because of this, the magnetic forces they feel also go in opposite directions. Side B feels a force into the page, and side D feels a force out of the page. These two forces together cause the loop of wire to rotate. An electric motor turns because two sides of a loop feel opposite forces due to an external magnetic field.

This rotation is the basis for most electric motors that involve turning motions.

Examples of Electric Motors

An electric car has an electric motor. The energy stored in the car's batteries is converted into the rotation of the wheels. Barack Obama in a Chevy Volt (Electric Car)

A food processor works on exactly the same principle. Electrical energy from the outlet is turned into rotation in the food processor, and if you attach blades to the part that turns, it can cut up your

The BMBF supports this development through its call for proposals on Key Technologies for Electric Mobility (STROM) (in German language only). The focus is on research and development for new, innovative electric vehicles, taking all the necessary sub-systems into account: funding is provided for work on entire vehicle systems, battery development and integration, energy management, and related materials research. A total of about €90 million will be made available between 2011 and 2014.

Production technologies for hybrid and electric drives with optimization targets relating to energy efficiency, reliability, production costs, recyclability, and high output and variant flexibility are supported under the call forSeries-flexible technologies for electric drives for vehicles (in German language only).

The call for proposals on Energy-efficient and safe electric mobility (in German language only) addresses two central areas in our efforts to develop competitive electric vehicles: 1. intelligent management of the limited electric power in plug-in hybrid vehicles and fully electric vehicles, and 2. aspects of functional security, both at component level and at system
