System of launch of the motor - the general information

General information

The only problem of the system of the launch of the motor secures the rotation of the motor with a sufficient speed for his departure.

The system of the departure is composed of an author, the battery recarregável, by the switch of the ignition, the alternation of traction and an electrical system that is joined.

The author represents the electric motor of a continuous current with varied excitement and the traction alternation eletromagnético installed on the outside. The author is composed of the case or the fixed part of the electric motor with windings of excitement, an anchor with the union obgonny, coverings with bearers of brush and the alternation of traction.

In the moment of the inclusion of an author through a curve of the alternation of traction of an author's current of the battery recarregável it begins to continue. The anchor of the alternation is implicated and contacts that they are isolated. At the same time the alternation anchor was seeing the lever of driving provide the promotion of a wheel of gear with the union obgonny, at the same time the nave of the union lights openings of screw of an end of an anchor of an author and spins also a wheel of gear that makes easy the entry of the last one in the gear with a garland of gear of a pendulum. Over the shut contacts of the alternation of traction there they pass the current windings of food of the fixed part of the electric motor and anchors and the anchor of an author begins to revolve together with a nave and the union obgonny.

After the launch of the motor the frequency of the rotation of a wheel of gear exceeds the frequency of the rotation of an anchor of an author. In this case the union obgonny had seen itself freely, and the torque is not transferred of a motor pendulum to an end of author's anchor. After an ignition key otpuskaniye the circuit of supply of electricity of windings of the traction alternation was seeing the switch of the ignition desconecta-se, the anchor of the alternation of traction is pulled out during one spring in an initial position, the contacts of the alternation desconectam-se and the wheel of gear of the gear of leaves of walk with a garland of gear of a pendulum.

The author with the implication alternation is located parallel to an end of inclination of the motor and it concentrated on the unity of power.

The activation of an author only happens in in the LEVER of selector transferred to the situation "N" or "P".

Measured by precaution

When it executes any work with the system of the launch of the motor it observes the next demands:

• To avoid an exit э / the motor out of the operation as a consequence of overheating does not include an author any more, of which during 15 seconds, - before the repeated inclusion waits not less than 1 minute. The long provorachivaniye of not the motor begun of an author leads to a congestion of it did not set the fuel alight in the catalytic converter that is loaded of an exit of the last one out of the operation as a consequence of the ignition in the moment of the implementation of departure;
• The author joins straightly the battery recarregável and his negligent treatment can be the reason of the ignition as a consequence of the short circuit;
• Before the works in the service of an author always desconectem a negative wire of the battery.
