Repair and car operation

In the car the generator of an alternating current with the rectifier is established.

The generator is a three-phase synchronous electric car with electromagnetic excitement. Tension is regulated by the built-in regulator of tension.

At operation of the generator the electric current proceeding on a winding of excitement, creates a magnetic stream round rotor poles. At rotor rotation under each tooth of a stator passes that southern, the North Pole of a rotor and the working magnetic stream passing through teeth of a stator, changes on size and tension. This variable magnetic stream creates an electromotive power in a stator winding.

At 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 the current does not pass through a winding of excitement. Tension of the generator falls, the regulator opens and again passes a current through an excitement winding. The frequency of rotation of a rotor of the generator is higher, the it is more time of the locked condition of a regulator, therefore, the more strongly tension on a generator exit decreases. Process of locking and unlocking of a regulator occurs to high frequency therefore tension fluctuations on an exit of the generator are not appreciable, and it is almost possible to consider it to the constants supported at level 13,6 – 14,6 Century.
