Mechanical Auxiliaries for Optimal Operation

14 auxiliaries provide optimal operation of energy storage elements. These elements store energy and subsequently provide mechanical energy. Accumulators like the flywheel, typically a solid disk mounted on a shaft, ensure regular rotation, preventing irregular motion when the driving force is not constant. It also slows shaft rotation when it tends to accelerate and resists stopping.

Elastic Elements

Elastic elements deform under force and return to their

Starter Motor: Principles, Components, and Operation

Starter Motor Principles

A conductor carrying an electric current within a magnetic field tends to move perpendicular to the magnetic field lines. The starter motor acts as an electromagnet due to the current flow, creating magnetic properties. This interaction with the stator poles results in circular motion.

Starter Motor Components

The starter motor assembly includes a DC electric motor and a gear mechanism. The electric motor has an armature that rotates within the stator, supported at both ends
