Starter - general information

GENERAL INFORMATION

Starter

1-forward cover
2-traction relay
3-casing
4-shchetkoderzhatel
5-stator
6-rotor
7-a driving gear wheel with the obgonny coupling

The starter represents the electric motor of a direct current with the mixed excitement with the electromagnetic traction relay.
The starter consists of the case or a stator with windings of excitement, an anchor with the obgonny coupling, covers with shchetkoderzhatel 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 anchor of the relay is involved and contacts of the relay become isolated. At the same time the relay anchor via the lever moves the obgonny coupling with a gear wheel. The nave the obgonny coupling turns on screw shlitsa of a shaft of an anchor of a starter turns as well a gear wheel that facilitates input it in gearing with a gear wreath of a flywheel. Through the closed contacts of the traction relay there is a current feeding windings of a stator and an anchor and an anchor of a starter starts to rotate together with a nave and the obgonny coupling.

After engine start frequency of rotation of a gear wheel exceeds frequency of rotation of an anchor of a starter. In this case the obgonny coupling is freely turned, and the torque is not transferred from an engine flywheel to a shaft of an anchor of a starter. After an ignition key otpuskaniye the power-supply circuit of windings of the traction relay via the switch of ignition is disconnected, the anchor of the traction relay is wrung out by a spring in a starting position, contacts of the relay are disconnected and the gear wheel of a drive leaves gearing with a gear wreath of a flywheel.
ATTENTION

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