Embodiment
In order to more clearly understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with drawings and Examples, the utility model is described further.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail in the following description so that fully understand the utility model, but, the utility model can also adopt and be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of the specific embodiment of prospectus below.
Embodiment, as Fig. 1, Fig. 2, shown in Fig. 3, the present embodiment provides a kind of double plate composition motor, comprise casing ontology and run through the rotating shaft 4 that casing ontology is in casing ontology center position, and casing ontology divides three part compositions, mainly comprise left end cap 1, right end cap 2 and be arranged on a left side, casing 3 between right end cap (1/2) forms, left end cap 1, chassis chamber is formed (certainly between right end cap 2 and casing 3, left end cap 1, right end cap 2 and casing 3 are equipped with, ensure the sealing of chassis chamber), chassis chamber internal fixtion is provided with stator 5, stator 5 is fixed on casing 3, the shape of stator 5 is discoid, for the annulus that the cylinder shape stator iron core be oppositely arranged by two forms.Stator core (not marking in figure) is for silicon-steel sheet coiled is around forming, stator core is provided with coil windings 9, left rotor disk 6 and right-hand rotation sub-disk 7 is respectively arranged with in the both sides of stator 5, permanent magnet 8 (permanent magnet is Nd-Fe-B magnet steel) is provided with between stator 5 and left rotor disk 6 and right-hand rotation sub-disk 7, permanent magnet 8 is fixed on a left side, in right-hand rotation sub-disk (6/7), left rotor disk 6 and right-hand rotation sub-disk 7 arrange teeth groove 15 away from the side of stator, the setting of teeth groove makes a left side, right-hand rotation sub-disk (6/7) is when rotating, produce certain wind-force, by adding projection on the tooth of teeth groove 15, further can increase wind-force, the temperature of better reduction motor, protruding shape preferably helical blade, in the present embodiment, protruding shape is helical blade, like this when rotation, larger wind-force can be produced, certainly, also can be left, other places of right-hand rotation sub-disk (6/7) add projection, left rotor disk 6 and right-hand rotation sub-disk 7 to be all sleeved in rotating shaft 4 and to be fixed on rotating shaft 4, rotating shaft 4 runs through stator 5.
By such design, at motor internal without the need to arranging any other heat sink again, utilizing the rotation of left and right rotor disk (6/7) that the cooling of motor internal can be realized, thus decreasing the device of motor internal, convenient processing, decreases processing cost simultaneously.
Consider the shape of the teeth groove 15 in left rotor disk 6 and right-hand rotation sub-disk 7, in conjunction with structure and the function of switched reluctance machines, in the present embodiment, left SRM stator 10 and right SRM stator 11 is respectively arranged with at the two ends of left rotor disk 6 and right-hand rotation sub-disk 8, left SRM stator 10 to be fixed on left end cap 1, described right SRM stator fixes 11 on right end cap 2 simultaneously.By such design, utilize the teeth groove 15 in left rotor disk 6 and right-hand rotation sub-disk 7 as the teeth groove of left SRM stator 10 and right SRM stator 11, make to form new motor, i.e. switched reluctance machines between left rotor disk 6 and right-hand rotation sub-disk 7 and left SRM stator 10 and right SRM stator 11.
By such design, when the use in later stage, respectively double plate magneto and switched reluctance machines are controlled by arranging two controllers.By controller, to when being energized in coil windings 9, produce magnetomotive force, the excitation field produced between this magnetomotive force and left rotor disk 6 and right-hand rotation sub-disk 7 interacts by rotating shaft 4 output mechanical power.And the left and right SRM stator winding (not shown) of switched reluctance motor can serial or parallel connection together, adopt a set of controller in addition, control left and right SRM stator winding simultaneously, it is energized, follow " magnetic resistance minimum principle " according to SR motor, the magnetic pull produced forms the electromagnetic torque of magnetic resistance character and makes rotor turns, and its rotating speed and torque are exported by rotating shaft 4, is equivalent to like this only have a switched reluctance machines to run.When two controllers are coil windings 9, left and right SRM stator winding electrifying simultaneously, namely two motors work simultaneously, have low speed high torque fan-out capability, can meet starting and the low speed hill climbing demands of electric automobile; When only having double plate magneto to work, motor is in high speed running status, and the high speed that can meet electric automobile travels; Only have switched reluctance machines to run, motor is in high-speed cruising state, can meet running at high speed of electric automobile.Therefore the independence of this motor or simultaneously powered operation, make it have low speed high torque and high-speed cruising ability.And, by this drived control, motor can be made to be in optimum efficiency running status all the time, thus to improve the comprehensive operation efficiency of motor, effectively can improve the mileages of continuation of electric automobile.
The conveniently dismounting of whole motor and installation, in the present embodiment, by the formation chassis chamber that is fixed together to pin screw 12 between left end cap 1, right end cap 2 and casing 3.Stator 5 is fixed on casing 3 by bolt 13.Permanent magnet 8 is fixed on left and right rotor disk (6/7) by screw 14.By such design, following when overhauling, more for convenience.
The above; it is only preferred embodiment of the present utility model; it is not restriction the utility model being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field; but everyly do not depart from technical solutions of the utility model content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present utility model is done above embodiment, still belong to the protection range of technical solutions of the utility model.
