Abstract
A kind of be used for single cylinder vapour, diesel engine be on the vehicle powered as the permanent magnetic constant voltage dc generator of power generator, this machine can be under variable rotation conditions, provides constant voltage to the load of fixed resistance value.It is characterized in that in inlaying the stator slot of armature coil, being fixed with the soft magnetism slot wedge of high permeability.This machine can be used on two-wheeled motor vehicle, hand tractor, tractor with small four wheels, agricultural three-wheel transporter and the spitkit as power generator.
Description
The present invention relates to electric generater of vehicle, be specifically related to a kind of permanent magnetic constant voltage dc generator, it comprises stator and rotor.
On the cyclecar, ship that with single cylinder vapour, diesel engine are power, adopt magneto alternator mostly.As: two-wheeled motor vehicle, hand tractor, tractor with small four wheels, agricultural three-wheel transporter, spitkit etc.But the output voltage of existing magneto alternator changes and can not regulate with change in rotational speed at present, and this has just influenced result of use.As: the light is dusky for brownout during the main frame tick-over, and overtension light is crossed bright very causing and burnt bulb during the main frame high speed operation, and its electric property can not satisfy the requirement of application.
The purpose of this invention is to provide a kind of permanent magnetic constant voltage dc generator, it can be under the condition of rotating speed wide variation, load to fixed resistance value provides the change in voltage scope very little power generator, in the hope of overcoming the deficiency of existing magneto alternator, satisfies the requirement of application.
The present invention is achieved in that the soft magnetism slot wedge of fixing a high permeability in stator is inlayed the groove of armature coil, the effect of this slot wedge is to make the magnetic flux of the armature mmf that motor produced when loaded work piece closed in stator range, this magnetic flux is (shown in dotted line in the accompanying drawing, hereinafter referred to as stopping magnetic flux) can stop the magnetic flux of the cutting armature coil that produces by p-m rotor effectively, this magnetic flux that stops magnetic flux is directly proportional with the magnetic flux of the required cutting armature coil that is produced by p-m rotor that stops, the induced potential that produces in armature coil when motor speed changes from low to high increases, armature winding increases the electric current of load output, the magnetic flux (shown in dotted line in the accompanying drawing) that stops that is produced increases, the magnetic flux by the cutting armature coil that p-m rotor produced that is blocked increases, the work magnetic flux reduces, and the effect of boosting that is produced becomes " slowly " because motor speed raises.Fix the soft magnetism slot wedge of a high permeability in stator is inlayed the groove of armature after, (needing the physical dimension of choose reasonable slot wedge) can make motor that the output voltage of load is limited in the very little excursion.When hanging down variation, the course of work of motor is opposite by height for motor speed.
The soft magnetism slot wedge of above-mentioned high permeability should design in very low magnetic flux density physical dimension, to guarantee the constant voltage effect of motor.
The present invention is because of only needing on the architecture basics of existing magneto alternator, replace original non magnetic slot wedge with the soft magnetism slot wedge of high permeability, so structure is simple especially, the output voltage that the present invention can overcome existing magneto alternator effectively changes the shortcoming that can not regulate with motor speed, example: after the 12V90W permanent magnetic constant voltage dc generator is installed in and opens all light on the 12 type tractor with small four wheels of Mount Taishan, closed circuit voltage in the working speed scope from empty wagons starting (420 rev/mins of engine speeds) to fully loaded (2200 rev/mins of engine speeds) at full speed is 11.5V to 135V, and the existing closed circuit voltage of magneto alternator under above-mentioned condition of work is 7V to 18V.
The permanent magnetic constant voltage dc generator that proposes according to the present invention is for being that cyclecar, the ship of power carries out the power generator that safe operation, operation provide function admirable with single cylinder vapour, diesel engine.

Fig. 1 is the principle profile of permanent magnetic constant voltage dc generator first embodiment of proposition according to the present invention.
Fig. 2 is the principle profile of second kind of embodiment of permanent magnetic constant voltage dc generator of proposition according to the present invention.
The details of the permanent magnetic constant voltage dc generator that proposes according to the present invention below in conjunction with description of drawings.
The first kind of embodiment that proposes according to the present invention as shown in Figure 1, slot wedge (1-3) stationary part of forming and the rotor matrix (1-5) that adopts cast iron to make that this embodiment comprises stator core (1-1), the armature coil (1-2) that adopts silicon chip to make and adopts electrical pure iron to make and the rotor portion composition of Nd-Fe-B permanent magnet (1-4) composition, among the figure dotted line be motor when loaded work piece, produced stop magnetic flux.
The second kind of embodiment that proposes according to the present invention as shown in Figure 2, this embodiment comprises the stationary part that stator core (2-1), armature coil (2-2) that adopts silicon steel sheet to make and the slot wedge (2-3) that adopts electrical pure iron to make are formed, the rotor portion composition of forming with rotor matrix (2-4) that adopts low charcoal steel plate to make and Nd-Fe-B permanent magnet (2-5), among the figure dotted line be motor when loaded work piece, produce stop magnetic flux.
