The armature is the key component of the starter motor, like the heart of the starter motor. It is composed of a steel shaft, a steel laminated core, copper windings, and a copper-segment commutator. The function of the armature is to convert electrical energy into mechanical energy, and to drive the start of the internal combustion engine through the motor output system.

The starter is a key component that guides the internal combustion engine from a static state to an automatic working state. The relationship between them is like a match and a candle. The starter is composed of a DC motor, a control system, and an output system. The pros and cons of the starter will affect the speed requirements of the internal combustion engine from a standstill to its automatic operation.
