The rectification voltage stabilizer is positioned between the cover cap and the back end cover, wherein, the stator is provided with two or more separate windings, and the number of windings of each winding is different with some more and some less. The utility model has the advantages that when the rotary speed is low, the automobiles have a constant output current to ensure that the automobiles can not conduct electricity; when the rotary speed is high, sufficient high-current can be output.
Description
The utility model relates to a kind of permanent magnet generator, is applicable to that various motor vehicles works fill the power supply of power supply.
At present, automobile current generator stator winding commonly used or the Y-connection of employing three-phase, adopt the three-phase triangle to connect, automobile-used electric equipment electricity consumption of the three-phase alternating current of its output steam supply behind rectifying and voltage-stabilizing and charge in batteries, the characteristics of star connection are line voltage height, output current is little, certain electric current output promptly when working, is also arranged in the slow-speed of revolution, but when high rotating speed, can not provide enough big electric current steam supply automobile-used, output current was big when delta-connected characteristics were high rotating speeds, but almost do not have electric current output during slow-speed of revolution work, like this, automobile is power shortage very easily.Obviously, all there is weak point at automobile in above-mentioned two kinds of generators aspect electricity consumption.
Goal of the invention of the present utility model has certain output current steam supply car to use when being to provide a kind of slow-speed of revolution, makes automobile be difficult for power shortage, during high rotating speed, can export enough the car permanent magneto of electric current greatly again.
Car permanent magneto of the present utility model is to realize like this, comprise cover cap, rectifying and voltage-stabilizing device, rear end cap, p-m rotor, stator, front end housing, the rectifying and voltage-stabilizing device is positioned between cover cap and rear end cap, wherein be equiped with two or more independently coils on the stator, the number of turn of each coil is all different, what have is many, and what have lacks.
During work, the output of each coil and rectification circuit are separately joined, under the drive of motor car engine, each coil has induced electromotive force to produce on the stator, and during time of engine low speed, the voltage height that coil turn is many has certain electric current output.During high rotating speed, the induction reactance that coil turn is few is low, can export big electric current, can satisfy the needs of the normal electricity consumption of automobile.
Here, the rectifying and voltage-stabilizing device mainly is made of one or above single-phase half-controlled bridge-type rectification circuit, one or above single phase half wave controlled rectifier, circuits for triggering, controllable silicon KP1, KP2 in the single-phase half-controlled bridge-type rectification circuit and the controllable silicon KP3 in the single phase half wave controlled rectifier form plus earth altogether and circuits for triggering IC earth terminal joins, controllable silicon KP1, KP2, KP3 trigger electrode join with circuits for triggering IC signal output part respectively, and the diode Z1 in the single-phase half-controlled bridge-type rectification circuit, Z2 common cathode and circuits for triggering IC signal input part join.
During work, a wherein end and diode Z1, the Z2 common cathode of the stator winding L1 that coil turn is few join, the other end links to each other with the negative electrode of controllable silicon KP3, the output of the stator winding L2 that coil turn is more links to each other with the input of single-phase half-controlled bridge-type rectification circuit respectively, the positive pole of the storage battery on the common cathode ground connection of diode Z1, Z2 and the motor vehicle links to each other, and the common plus earth of controllable silicon KP1, KP2, K3 links to each other with the negative pole of storage battery.
Compared with the prior art the utility model has simple, the easy-to-connect of coiling, can not produce enough electric currents when power shortage, high speed in the time of guaranteeing automobile low speed, control circuit is simple, uses element few, and cost is low, controllable silicon plus earth altogether links to each other with battery terminal negative, and is easy for installation, good heat dissipation effect.
Fig. 1 is the structural representation of the utility model permanent magnet generator;
Fig. 2 is the structural representation of the utility model rectifying and voltage-stabilizing device.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail;
As shown in Figure 1, permanent magnet generator of the present utility model mainly is made of cover cap 1, rectifying and voltage-stabilizing device 2, rear end cap 3, p-m rotor 4, stator 5, front end housing 6, belt pulley 7, rectifying and voltage-stabilizing device 2 is arranged on 1 of rear end cap 3 and cover cap, stator 5 places in the front end housing 6, p-m rotor 4 is actively socketed on 3 of front end housing 6, rear end caps, wherein be equiped with two independently coils on the stator 5, the number of turn of one of them coil is more, and another coil turn is few.
As shown in Figure 2, rectifying and voltage-stabilizing device of the present utility model is mainly by a single-phase half-controlled bridge-type rectification circuit 8, a single phase half wave controlled rectifier 9, circuits for triggering IC constitutes, controllable silicon KP1 in the single-phase half-controlled bridge-type rectification circuit 8, controllable silicon KP3 in KP2 and the single phase half wave controlled rectifier 9 forms plus earth altogether and circuits for triggering IC earth terminal joins, controllable silicon KP1, KP2, the KP3 trigger electrode joins with circuits for triggering IC signal output part respectively, the diode Z1 in the single-phase half-controlled bridge-type rectification circuit 8, Z2 common cathode and circuits for triggering IC signal input part join.
During work, the end of the stator winding L1 that coil turn is few joins with diode Z1, Z2 common cathode, the other end links to each other with the negative electrode of controllable silicon KP3, the output of the stator winding L2 that coil turn is more links to each other with the input of single-phase half-controlled bridge-type rectification circuit respectively, the positive pole of the storage battery on the common cathode of diode Z1, Z2 and the motor vehicle links to each other, and the common plus earth of controllable silicon KP1, KP2, K3 links to each other with the negative pole of storage battery.Winding L 1 and winding L 2 parallel connections are sent alternating current simultaneously by diode Z1, Z2 and controllable silicon KP1, KP2, KP3 is to charge in batteries and electric, when the storage battery both end voltage is low, circuits for triggering IC just exports triggering signal and triggers the controllable silicon conducting, when the storage battery both end voltage is higher than circuits for triggering IC set point, circuits for triggering IC just stops to export triggering signal, controllable silicon ends, when the storage battery both end voltage drops to certain value, circuits for triggering IC exports triggering signal again and impels the controllable silicon conducting, to storage battery power supply, go round and begin again like this, guarantee that all the time the storage battery both end voltage is near assigned voltage.
