Starter Armature

A starter armature is a component found in a starter motor, which is used to start an internal combustion engine. The starter motor is responsible for initiating the engine’s rotation until it can generate power on its own.

The armature is a cylindrical assembly that consists of a core made of iron or steel laminations and windings of insulated copper wire. It is designed to convert electrical energy into mechanical energy. When an electrical current is supplied to the windings, a magnetic field is created, which interacts with the permanent magnets or field coils in the starter motor to produce rotational motion.

The starter armature is typically connected to a gear mechanism, such as a pinion gear, which engages with the engine’s flywheel or flexplate to turn the engine’s crankshaft. As the armature rotates, it transfers torque to the engine, allowing it to start.

The design and construction of a starter armature can vary depending on the specific application and the type of starter motor used. However, its primary function remains the same – to convert electrical energy into mechanical energy and initiate the engine’s rotation during the starting process.
