Starter-Generator Armature

A starter-generator armature is a component found in a starter-generator system, which is commonly used in automotive applications. The armature is a rotating part of the system that consists of a coil of wire wound around a core. It is responsible for generating electrical power and providing the initial torque to start the engine.

In the starting mode, the armature acts as a starter motor, drawing electrical power from the battery and converting it into mechanical energy to crank the engine. Once the engine is running, the armature switches to generator mode, where it generates electrical power to charge the battery and power the vehicle's electrical systems.

The armature is typically made of a ferromagnetic material, such as iron or steel, to enhance its magnetic properties. The coil of wire wound around the core creates a magnetic field when an electrical current passes through it. This magnetic field interacts with the magnetic field of the system's stator, which is a stationary component, to produce the necessary torque or electrical power.

Overall, the starter-generator armature plays a crucial role in the operation of a starter-generator system, providing both starting and generating functions for the vehicle.
