Description
Permanent-magnet brushless DC generator described in the utility model belong to a kind of be used for automobile, tractor, as the generating equipment in field such as oceangoing ship.
Prior aries such as present existing automobile current generator, tractor, generator, fishing boat generator all must have the copperhead and the rotor winding of carbon brush by harness on generator amature, the energized circuit that also must have storage battery and voltage-regulation composition simultaneously can generate electricity.Especially in vehicle, boats and ships long-time running process, various faults often appear in generator, as carbon brush wearing and tearing, carbon brush and copperhead loose contact, copperhead damage, rotor winding broken string and scaling loss, have brought difficulty so just for operating personnel and maintenance personal.Excitation DC generator of the prior art in addition increases charging current because of voltage regulator job insecurity sometimes sometimes, and then phenomenon appears overcharging in storage battery, thereby significantly reduces the life of storage battery.If accumulator internal resistance changes, the generator charging electric current also changes thereupon, then the uncontrollable generator charging electric current of operating personnel at this moment.At existing problem in the prior art, design a kind of novel permanent-magnet brushless DC generator, be very necessary to overcome existing problem.
In view of existing problem in the prior art, the purpose of this utility model is the novel permanent magnetic formula brushless DC generator of a kind of novel structure of invention, advanced in performance, high efficiency, energy savings, to adapt to the needs of work on the spot.Because the utility model adopts the magneto rotor, thus cancellation armature conversion equipment, so simple in structure, cheap, be a kind of practical novel permanent magnetic formula brushless DC generator that is suitable for.
The utility model provides a kind of permanent-magnet brushless DC generator, and its structure is made up of body, rotating shaft, rotor, stator, binding post.Rotor is the magneto structure, and stator has 12 groove setting-in leads and constitutes 6 windings, wherein is provided with three cover individual event windings.Rotating shaft is the copper axle, and rectifying device is housed in body, and body is provided with outward transfers stream device and binding post.The rotor of magneto structure described in the utility model is made up of magnetic conduction sheet, and has 12 pairs of magnetic poles.Three single-phase windings of institute's setting-in in the stator described in the utility model can be divided into single single-phase winding according to the power difference and connect, and two single-phase windings connect and the parallel connection of three individual event windings.Rectifying device described in the utility model is made of one group of four rectifier diode, is installed in the middle of stator winding and the binding post.Accent stream device described in the utility model can be change over switch or transfer the stream binding post that binding post is divided into positive terminal and negative terminal, and is connected with bridge-type rectifier by gusset piece respectively.Accent stream binding post described in the utility model has four, can carry out the parallel connection of single single-phase winding, two single-phase windings, three single-phase windings respectively according to the different needs of power.
The utility model is a kind of economic, practical, easy to maintenance, reliable generator.Owing to the utlity model has no storage battery, non-carbonate, no rotor winding, no-voltage adjuster, so can be applicable to fields such as tractor, agricultural automobile, boats and ships widely.Be example with the fishing boat if away from the continent then the generator stream time will reach a few hours, if breaking down, generator will be brought massive losses with fisherman's safety economically like this, and at present the excitation-type generator must be furnished with storage battery, so the next generator of situation that does not have electricity or a no storage battery at storage battery can not be worked.In sum as can be known, extensive use of the present utility model will have huge economic benefit and remarkable social benefit.
The utility model has three accompanying drawings, and wherein accompanying drawing 1 is a permanent-magnet brushless DC generator structure chart.
Accompanying drawing 2 is the accent current circuit schematic diagram of accompanying drawing 1.
Accompanying drawing 3 is the stator winding installation expanded view of accompanying drawing 1.
Among the figure: (1) body (2) belt pulley (3) rotating shaft (4) rotor (5) rectifier diode (6) is transferred stream binding post (7) positive terminal (8) negative terminal (9) gusset piece (10) magnetic conduction sheet (11) stator (12) support
The utility model specific embodiment as shown in drawings, its structure has 12 grooves for to be fixed with stator (11) in body (1) on stator (11), institute rolls off the production line and forms 6 windings.Rotating shaft (2) is installed on the bearing of (1) two face of body.Be fixed with rotor (4) in rotating shaft (3), this rotor (4) is the magneto structure, promptly constitutes 12 pairs of magnetic poles by magnetic conduction sheet (10) manufacturing.Rotating shaft (3) is then formed by the copper material manufacturing, thereby can prevent that magnetic from producing the loop, guarantees the magnetic circuit operate as normal.Method for rectifying has been taked the single-phase bridge rectification device, is made up of four silicon rectifier diodes, is located at generator inside and is connected with stator (11).And be provided with two usefulness of standby diode in generator inside for maintenance.Rectifying device is connected as shown in Figure 2 with stator (11) winding, is equipped with two groups in a side of body (1) and transfers stream binding posts (6), two every group.And be connected with the corresponding points of fixed (11) windings in the accompanying drawing 2.The positive and negative polarities of rectifying device are connected on body (1) the outer positive terminal (7) and negative terminal (8).In body (1) opposite side rotating shaft (3), be fixed with belt pulley (2) in order to be connected with prime mover.Two supports (12) of body (1) lower end are in order to fixing usefulness.
Operation principle of the present utility model is, rotor (4) is rotated, because of magnetic field on rotor (4), rotor (4) is located in the stator winding again, so by cutting magnetic line, produce induced electromotive force and induced voltage in stator winding.Through the work of rectifying device by anodal, negative terminal (7,8) output DC.Owing to be provided with the single-phase winding of three covers in the stator (11), so can be by exchanging the A of stream binding post (6)
