Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, from scheming, can find out, the utility model be take the permanent magnet generator that gasoline engine is power, comprises rotor and stator 4 two large divisions, and rotor doubles as gasoline engine flywheel simultaneously.Rotor mainly consists of rotor case 1, rotor flange dish 3 and magnet steel 2, and rotor case 1 is processed into by steel plate stretching, and rotor case 1 and rotor flange dish 3 rivet together, the spaced rare earth magnetic steel 2 of the rotor case even gluing polylith south poles of 1 inner circle.Stator 4 is silicon steel laminations Shangrao enamelled wire.At a certain magnet steel 2 of rotor case, be provided with the leakage field groove 5 that runs through rotor case thickness around, it is outside to rotor case that the magnetic field that this magnet steel produces spills part by leakage field groove 5, and this outer stray field is used for replacing lighting a fire magnet steel as gasoline engine ignition magnetic field.
Described leakage field groove 5 surrounds corresponding magnet steel for rectangular distribution Si Dao， tetra-road leakage field grooves, sees Fig. 2.These grooves make rotor case herein have magnetic field outward, and this magnetic field spilling is for gasoline engine ignition, and rotor periphery is no longer installed the magnet steel that is specifically designed to gasoline engine ignition.
See Fig. 3, described leakage field groove 5 can be to be also a shape distribution San road, and wherein one end of that parallel twice leakage field groove is positioned at ，San road, rotor case edge leakage field groove by corresponding magnet steel semi-surrounding.The distortion of three leakage field groove essence Shi Si road, road leakage field grooves, is equivalent to be positioned at outside rotor case because one end of that parallel twice leakage field groove is positioned at rotor case edge ， tetra-road leakage field grooves, therefore develop into three roads.
See Fig. 4, described leakage field groove can be also that to be twice and " C " type opening of " C " type (or door type) relative, and twice leakage field groove surrounds corresponding magnet steel.These twice " C " type (or door type) structure, essence is also the distortion in rectangular distribution Si road.
Certainly, no matter that set-up mode, when leakage field groove is set, should make rotor case and magnet steel that leakage field groove surrounds keep being connected of necessary intensity with other position rotor case.
In order to realize the moment of inertia balance of rotor, at rotor case 1 other position, be provided with the structure for balance leakage field groove, this structure can be breach or groove or hole or hole etc., as long as can make not leakage field of the whole dynamic balancing of rotor case and this place's breach.Conventionally this balanced structure is arranged on rotor case opposite relative with aforementioned leakage field groove in rotor case.As shown in Figure 5, this balanced structure is arranged on rotor case opposite relative with aforementioned leakage field groove in rotor case and is breach 6 forms.
The utility model another kind be take the permanent magnet generator that gasoline engine is power, comprise equally rotor and stator two large divisions, rotor doubles as gasoline engine flywheel, and rotor mainly comprises rotor case, rotor flange dish and some magnet steel, and magnet steel is installed on rotor case inner periphery with south poles interval mode.Itself and front structure difference are, in rotor case and a certain magnet steel correspondence position, have door opening, in door opening, install and are filled with non-magnet material, and the magnet steel corresponding with this door opening is arranged in this non-magnet material or inner surface.The magnetic field that the magnet steel corresponding with this door opening produces is delivered to rotor case outside by non-magnet material, and magnet steel can be lighted a fire as gasoline engine ignition magnetic field for replacing equally in this magnetic field that is delivered to rotor case outside, thereby cancels special igniting magnet steel.
By above-mentioned improvement of the present utility model, owing to need to special igniting magnet steel not being set on week at rotor outer circle, so rotor outer circle do not have ledge, compact conformation, and processing and manufacturing is easy.
The utility model replaces the outer special igniting magnet steel arranging of rotor by the magnet steel with arranging in rotor case, realizes magnetic field igniting, thereby reach structure, simplifies, and is easy to the object of processing and manufacturing.It mainly contains two kinds of implementations, and a kind of is that leakage field groove is set in rotor case, and the magnetic field that magnet steel produces spills as igniting magnetic field by leakage field groove.Another kind is by non-magnet material, to be replaced the metal magnetic conducting material of rotor case, and the magnetic field that magnet steel produces is spilt as igniting magnetic field by non-magnet material.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
