Fit Model                                                                                              

(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 magnetic field.
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 AC.
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 poles.
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 slots.

(C) rectifier                                                                                             

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.
