Starter - the general data



1 - a forward cover
2 - the traction relay
3 - a casing
4 - щеткодержатель
5 - статор
6 - a rotor
7 - приводная a gear wheel with обгонной муфтой

The starter represents the electric motor of a direct current with the mixed excitation with the electromagnetic traction relay.
The starter consists of the case or статора with windings of excitation, an anchor with обгонной муфтой, covers with щеткодержателями and the traction relay.

At starter inclusion through a winding of the traction relay of a starter the current from the accumulator starts to proceed. The relay anchor is involved also relay contacts become isolated. Simultaneously the relay anchor through the lever moves обгонную муфту with a gear wheel. The nave обгонной муфтой turns on screw шлицах a shaft of an anchor of a starter turns as well a gear wheel that facilitates its input in gearing with a gear wreath of a flywheel. Through the closed contacts of the traction relay there is a current feeding windings статора both anchors and the starter anchor starts to rotate together with a nave and обгонной муфтой.

After start of the engine frequency of rotation of a gear wheel exceeds frequency of rotation of an anchor of a starter. In this case обгонная муфта it is freely turned, and the twisting moment is not transferred from an engine flywheel to a shaft of an anchor of a starter. After отпускания the ignition key the feed circuit of windings of the traction relay through the ignition switch is disconnected, the anchor of the traction relay is wrung out by a spring in a starting position, relay contacts are disconnected also a drive gear wheel leaves gearing with a gear wreath of a flywheel.

The starter represents an exchange component. It means that the damaged starter at purchase of the repaired or new is set by the manufacturer off. Therefore it is necessary to take an old starter with itself.
