Starter

Starter - a DC motor and the mixed excitation electromagnetic traction relay. The starter consists of a stator (housing) with excitation windings (coils), anchors Freewheel, covers with brush holder and the traction relay.

The starter is activated by pulling the starter relay coil current begins to flow from the battery, the relay anchor is pulled and the relay contacts are closed. Simultaneously the relay anchor through the lever moves the overrunning clutch with the gear. The freewheel hub rotates helical splined shaft together with the starter pinion, which facilitates its entry into engagement with the flywheel. Through the closed contact magnetic switch is current feeding the stator winding and the armature, the armature and the starter starts to rotate along with the hub, and the overrunning clutch.

After the engine starts, pinion speed exceeds the speed of the armature starter overrunning clutch turn freely and torque is transferred from the flywheel to the starter shaft. After releasing the ignition feed circuit winding traction relay opens, the anchor of the traction relay is wrung out by a spring in its original position, the relay opens and the drive gear is disengaged from the flywheel.
