Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of winding level of rotor coil that makes and reduces, and alleviates rotor weight, reach bring to power density, reduce exciting curent, promote efficient, and be easy to change the integral type motor generator of constant of the machine and tool handled easily.
Background technology
Motor is used in daily life widely, and it generally is divided into direct current machine and alternating current machine, and the armature winding of direct current machine is arranged on the rotor, and the magnetic field winding is arranged on stator, and the armature winding of alternating current machine places stator mostly, and magnetic field is wound on rotor.Again, alternating current machine produces the principle of voltage, is the magnetic field winding that drives the AC machine rotor with prime mover, makes it form rotating magnetic field, and allows the armature winding of stator produce activation voltage and to induce three-phase alternating-current supply.
Cooperate and consult Fig. 4 and shown in Figure 5, it is respectively the decomposing schematic representation and the assembled sectional view of existing alternating current generator, wherein, stator core 90 winding stator coils 91 also are fixedly arranged in the stator cage 92, rotor 6 is arranged in stator core 90, and being hubbed at stator cage 92 with axle 62, rotor 6 peripheries and stator core 90 endoporus form the gap.Left pole plate 70 and right pole plate 80 are set on rotor 6, left and right pole plate 70,80 peripheries are laid the pole piece 73,83 of several pieces interfix tool spacings, left and right pole plate 70,80 relative inner are one-body molded go out in protuberance 71,81, perforation 72,82 covers are set in the interior protuberance 71,81 are fixed on the axle 62, interior protuberance 71,81 side faces insert coil holder 60.Coil holder 60 side face winding rotor coils 61, the sheathed flabellum 64 in left and right pole plate 70,80 outsides, and having the positioning seat of slip ring 65,66 in axle 62 1 end settings, brushes set in slip ring 65,66 and the stator cage 92 contacts, but the conducting electric current enters rotor coil 61 generation magnetic fields.And threaded portion 63 being set at axle 62 other ends, the belt pulley that locks on the threaded portion 63, belt pulley then connect prime mover with the belt winding.
Above-mentioned existing alternating current generator, when rotating in prime mover activation and with the belt drives belt pulley, can drive rotor 6 rotations, and because import electric current in the rotor coil 61, make the rotation of rotor 6 form the rotation electromagnetic field, the magnetic line of force that produces on rotor coil 61 surfaces can flow to the pole piece 73,83 to inserting, and makes one side pole piece 73 be the S utmost point entirely, and another side pole piece 83 is the N utmost point entirely.When rotor 6 rotations, the N utmost point and S move extremely alternately, the variation that the magnetic line of force of stator produces, as shown in Figure 6, the magnetic line of force that rotor coil 61 produced can enter stator coil 91 by protuberances 81 in the right pole plate 80, right pole plate 80 pole pieces 83, and enter protuberances 81 in protuberances 71 in left pole plate 70 pole pieces 73, left pole plate 70, the right pole plate 80 via stator coil 91, form the magnetic line of force stream of a sealing.At this moment, enter the magnetic line of force of stator side,, make stator coil 91 changed by the magnetic line of force and the generation starting voltage, induce three-phase alternating-current supply because of by stator coil 91 as power coil.
