Generators and Motors | Physics in Motion

Front

Alternating current

Back

A constantly reversing current.

Front

Commutation

Back

The electromechanical process by which direct current is turned into alternating current.

Front

Direct current

Back

Current that runs in only one direction.

Front

Electromagnetic Induction

Back

Generating electric current from the motion of a conductor through a magnetic field.

Front

Faraday's Law

Back

A law that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force.

Front

Generators

Back

Devices that convert mechanical energy into electrical energy. A generator uses motion in a magnetic field to produce current.

Front

Motors

Back

Devices that convert electrical energy into mechanical energy.

Front

rotor

Back

A moving component of an electromagnetic system in an electric motor or generator. Its rotation is due to the interaction between the windings and magnetic fields, which produces a torque around the rotor's axis.

Front

Stator

Back

The stationary component of an electric motor or generator.

Front

Galvanometer

Back

A device that uses an electromagnet to detect small amounts of current.
