(A) the rotor
The function of the rotor is to produce a rotating magnetic field.
The rotor is composed of claw pole, yoke, magnetic field winding,
collecting ring and rotor shaft.
The rotor shaft is pressed with two claw poles, two claw pole each
have six beak-shaped magnetic pole, the claw pole cavity is
equipped with magnetic field winding (rotor coil) and yoke.
The collecting ring is composed of two copper rings which are
insulated from each other. The collecting ring is mounted on the
rotor shaft and insulated from the shaft. The two collecting rings
are connected with the two ends of the magnetic field winding.
When the two sets of access ring into the direct current (through
the brush), the magnetic field winding current through, and produce
axial flux, so that the claw pole is magnetized to N pole, the
other is magnetized as S pole, thus forming Six pairs of
intertwined poles. When the rotor rotates, it forms a rotating
The magnetic circuit of the alternator is: yoke → N pole → air gap
between rotor and stator → stator → air gap between stator and
rotor → S pole → yoke.
(B) the stator
The function of the stator is to produce alternating current.
The stator consists of a stator core and a stator.
The stator core is stacked by a silicon steel sheet with grooves in
the inner ring, and the wires of the stator windings are embedded
in the grooves of the core.
Stator winding has three-phase, three-phase winding using star
connection or triangular (high power) connection, can produce
Three-phase windings must be required to be wound in order to
obtain the same frequency, amplitude equal, phase difference of 120
° three-phase electromotive force.
1. The distance between the two effective edges of each coil should
be equal to the distance occupied by a magnetic pole.
2. The distance between the adjacent edges of each phase winding
should be equal to or equal to the distance occupied by a pair of
3. The three sides of the three-phase winding should be separated
from each other 2π + 120o electrical angle (a pair of magnetic pole
space occupied by 360o electrical angle)
In the domestic JF13 series of alternators, a pair of magnetic
poles accounted for 6 slots of the spatial position (60o electrical
pressure per slot), a magnetic pole of the three slots of the
spatial position, so each coil two effective edge position interval
is 3 The distance between the edges of the adjacent windings of
each phase winding is six slots, and the distance between the edges
of the three-phase windings may be two slots, eight slots, and four
The alternator rectifier's function is to convert the three-phase
alternating current of the stator windings into direct current. The
rectifier of the 6-pipe alternator is composed of six silicon
rectifier diodes consisting of three-phase full-wave bridge
rectifier circuit. Or welding) on two boards.
1. Characteristics of Silicon Rectifier Diode for Automobile
(1) large current, forward average current 50A, surge current 600A;
(2) reverse voltage is high, reverse repeat peak voltage 270V,
reverse non-repetitive peak voltage 300V;
(3) Only one lead is shown in Figure 2-9. And some of the diode
lead is the cathode, and some of the diode lead is negative, the
lead is the cathode of the tube called the positive tube, the lead
line for the negative tube called the negative tube, so that the
rectifier diode with positive and negative diodes.
(D) end cover
The end cap is generally divided into two parts (front cover and
rear cover), acting as a fixed rotor, stator, rectifier and brush
assembly. The end cap is generally made of aluminum alloy, one can
effectively prevent leakage of magnetic, and second, aluminum heat
dissipation is good.
The rear cover is equipped with a brush assembly, a brush, a brush
holder and a brush spring. Brush the role of the power supply
through the collector ring into the magnetic field winding. See
Magnetic field winding (two brushes) and the generator connection
is different, so that the generator is divided into two types of
internal and external
1. Internal generator: magnetic field winding negative brush
directly from the generator (and the shell directly connected). See
2. Outside the generator type: the two windings of the magnetic
field windings are insulated from the housing. See Figure 2-13b
Outside the ground-type generator magnetic field winding negative
(negative brush) then adjust the regulator, and then through the
