How does a generator rotate?

In a gas-powered generator, an internal combustion engine provides the mechanical force needed to generate a current. The engine spins a shaft which rotates an electromagnet (armature). The rotating armature spins inside a stationary magnetic field (stator) to produce electrical current through copper wiring.

What is armature in AC generator?

In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine.

Is armature part of AC generator?

Armature. The part of an AC generator in which the voltage is produced is known as an armature. This component primarily consists of coils of wire that are large enough to carry the full-load current of the generator.

How AC changes its direction?

As the wire spins and periodically enters a different magnetic polarity, the voltage and current alternate on the wire. This current can change direction periodically, and the voltage in an AC circuit also periodically reverses because the current changes direction.

Why armature winding is stationary in an alternator?

1) The current is drawn directly from fixed terminals on the stator without the use of brush contacts. 2) The insulation of stationary armature winding is easier. 3) The number of sliding contacts (slip rings) is reduced. Moreover, the sliding contacts are used for low-voltage DC Source.

How is alternating current made?

In an alternator, a loop of wire is spun rapidly inside of a magnetic field. This produces an electric current along the wire. As the wire spins and periodically enters a different magnetic polarity, the voltage and current alternate on the wire.

How does a armature work?

In electrical engineering, an armature is the component of an electric motor which carries alternating Current. When the machine or motor is used as a motor, this EMF opposes the armature Current, and the armature converts electrical power to mechanical power in the form of Torque and transfers it via the shaft.
