Definitions:

Alternators

Machines that convert mechanical energy to electrical energy by producing alternating current, commonly used in cars to charge the battery and power the electrical system when the engine is running.

Revolving-field-type

The revolving-field-type refers to a design in electrical machines, particularly alternators, where the magnetic field rotates around a stationary armature, inducing an alternating current.

Non-rotating Part

Components in machinery or devices that do not move around an axis, contrasting with rotating parts, typically providing structural support or enclosing moving parts.

Stator

The stationary winding of an AC motor.
