The generator of alternating current with the rectifier is installed in the car.
The generator is a three-phase synchronous electrical machine with electromagnetic excitement. Tension is regulated by the built-in regulator of tension.
During the operation of the generator the electric current proceeding on an excitement winding creates a magnetic flux around rotor poles. At rotation of a rotor under each tooth of the stator passes the southern, the North Pole of a rotor and a working magnetic flux passing through stator teeth changes in size and tension. This variable magnetic flux creates the electromotive force in a stator winding.
With a high frequency of rotation of a rotor of the generator when tension of the generator becomes more, than 13,6 – 14,6 In, the regulator of tension is locked and current does not pass through a winding of excitement. Tension of the generator falls, the regulator opens and again passes current through an excitement winding. The frequency of rotation of a rotor of the generator is higher, the time of the locked condition of the regulator is more, therefore, the stronger tension at the generator exit decreases. Process of locking and unlocking of the regulator happens with high frequency therefore fluctuations of tension at the exit of the generator are not noticeable, and can almost consider it the constants supported at the level of 13,6 – 14,6 Century.
