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
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
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.
