4-5-1 Starter Motor
To start the engine, the starter motor rotates the ring gear installed on the engine flywheel with the pinion gear
engaged with the ring gear so that the force generated by the rotation exceeds the resistance including the engine
compression pressure and all frictional force. The starter motor consists of the following major parts : a motor which
generates torque ; a pinion which transmits the torque to the engine ring gear ; a clutch ; and a magnetic switch
which pushes out the pinion and turns on and off the principal current.
