Design and operation of the generator

The generator consists of the following parts: stator, rotor, cap from the slip rings with a rectifier unit and the integral device, the cover of the drive, fan and pulley. The stator is assembled from separate plates connected to the package, and has 36 slots, which are incorporated in the two-phase windings connected in star and in parallel. The rotor of the generator consists of a field coil wound on a separate sleeve to the ends of which abut two kogteobraznyh pole tip dvenadtsatipolyusnuyu forming a magnetic system, and the two slip rings, to which the soldered ends of the field winding. The resistance of 3.7 ohm winding of ± 5% at 20 ° C. Bush, pole pieces and the xcontact ring pressed to the shaft. Shaft rotates in two ball bearings closed with rubber seals. Ball 6 1800603KS9SH1 installed in the lid the drive and the 6-ball 180502K1S9SH1 - from the xcontact rings. The cover of the slip rings made of aluminum alloy has a ventilation window and leg for mounting on the engine. In a cover mounted rectifier unit, a plastic brush holder and the an integral unit. The integral control device is voltage, performed on silicon semiconductor micronutrients. Brush holder and regulator attached to the casing of the integral device. The cover of the actuator is made of aluminum alloy, has ventilation windows, and two legs, one of which is used for fastening generator on the engine bracket and the other with a threaded hole - for fixing the tension bars. On the lid there are two threaded holes for the MB fixing a stripper. Pulley and the fan mounted on the generator shaft and fixed to the pins nut with spring washer. When you turn the ignition switch current of the battery is through the field winding of the rotor, creating a magnetic flux of a permanent direction. During the rotation of the rotor magnetic flux crosses three-phase stator winding, inducing in it a variable in magnitude and direction voltage which is rectified by rectifier unit and fed into the network of the car. Series with the field winding through slip rings and brushes connected integral device that regulates the voltage of the generator within the prescribed limits by adjusting the excitation current.
