Description
Technical field:
The present invention relates to a kind of permanent magnet generator, be applicable to that various motor vehicles works fill the power supply of power supply.
Background technology:
At present, automobile current generator stator winding commonly used or the Y-connection of employing three-phase, adopt three triangles 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 the characteristics of delta connection 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.
Summary of the invention:
There is certain output current steam supply car to use when the object of the present invention is 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.
The present invention realizes like this, comprise rear end cap, p-m rotor, stator, front end housing, the rectifying and voltage-stabilizing device, it is characterized in that being equiped with on the stator two or more independently coils, the number of turn difference of each coil, what have is many, what have lacks, the rectifying and voltage-stabilizing device is mainly by one or above single-phase half-controlled bridge-type rectification circuit, one or above single phase half wave controlled rectifier, circuits for triggering constitute, controllable silicon KP1 in the single-phase half-controlled bridge-type rectification circuit, controllable silicon KP3 in KP2 and the single phase half wave controlled rectifier 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, diode Z1 in the single-phase half-controlled bridge-type rectification circuit, Z2 common cathode and circuits for triggering IC signal input part join, the output of the stator winding that coil turn is few and diode Z1, the Z2 common cathode joins, the other end links to each other with the negative electrode of controllable silicon KP3, the output of the stator winding that coil turn is more links to each other with the input of single-phase half-controlled bridge-type rectification circuit respectively, diode Z1, the positive pole of the storage battery on the common cathode of Z2 and the motor vehicle links to each other controllable silicon KP1, KP2, the common anode of KP3 links to each other with the negative pole of storage battery.
During work, 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.
Have the following disadvantages in order to overcome fan external permanent magnetic engine:
1, cooling air passway is oversize, can not drain by very fast heat with generator, thereby makes the generator heating serious.
2, rotor adopt be stained with when removing heavy method smoothing weighing apparatus difficult removing of iron filings.
Constitute the front end housing of electric machine casing, rear end cap radially, be axially arranged with ventilation hole.During work, cooling air is divided into two-way, and one the road enters cooling rectifying and voltage-stabilizing device from the cover cap axial ventilation hole, enters in the rear end cap by the rear end cap axial ventilation hole then and directly stator winding is cooled off, and drains from rear end cap radial ventilation hole at last.Another transportation work style the past end cap axial ventilation hole enters in the front end housing and directly stator winding is cooled off, and last end cap radial direction ventilation hole is in the past drained.
Here, the both sides of the p-m rotor in the electric machine casing are connected with centrifugal fan, and centrifugal fan is to be made by non-magnet material.Like this, the cooling air that enters in the housing directly cools off stator winding under the drive of centrifugal fan, thereby has improved cooling effect.
Compared with the prior art the present invention 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.Fan is built in the electric machine casing, the heater element of the direct cooled electric generator of wind that fan blew out and aspirated, and cooling air duct is shorter, and the heat of generator just can in time be drained like this, good cooling results; Utilize the fan of built-in non-magnet material system to remove material smoothing weighing apparatus, the smear metal that is produced can not be bonded on the rotor, therefore than easy-clear.
