Switch motor.
Background technology
Magneticflux-switching type permanent magnetism（FSPM）Motor is as a kind of stator permanent magnetic type electric of new structure, and its structure is completely not
It is same as rotor permanent magnet type motor.The rotor portion of common FSPM motors is similar with switched reluctance machines, is salient-pole structure, turns
It is both without winding or very simple without permanent magnet, structure on son.However, due to there was only permanent magnet excitation, its adjustable magnetic is limited in one's ability, institute
So that someone have studied electro-magnetic flux switching motor, although improving adjustable magnetic ability, its efficiency and power density are relatively low.It is comprehensive
Close both advantage and disadvantage, the mixed excited magnetic pass switch motor with two magnetic potential sources (permanent magnet and Exciting Windings for Transverse Differential Protection) meet the tendency of and
It is raw.
Its stator outer ring leakage field of existing flux switch motor is serious, and magnetic field utilization rate is low.Cause certain energy waste.
The content of the invention
The defects of the utility model purpose is to be directed to existing mixed excited magnetic pass switch motor, there is provided one kind energy-conservation drop
Consumption, self-power generation type internal rotor flux switch motor.
The utility model to achieve the above object, adopts the following technical scheme that：
Self-power generation type internal rotor flux switch motor, including external stator and internal rotor, it is characterised in that：The internal rotor is
Outer round belt toothing；The external stator is internal tooth arrangement, and armature winding, the armature are wound with the stator iron core tooth of external stator

Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is motor operation principle schematic diagram.
The similar transformer principle figure that Fig. 3 is armature winding, stator disc is formed with outside winding.
Embodiment
A kind of self-power generation type internal rotor flux switch motor as shown in Figure 1, including external stator 1 and internal rotor 7.Internal rotor 7
For outer round belt toothing, there are 10 rotor core teeth 5.External stator 1 is internal tooth arrangement, has 12 stator iron core tooths 2.It is outer fixed
Armature winding 4 is wound with the stator iron core tooth 2 of son 1, the center of armature winding 4 has permanent magnet 3, and the rear portion of stator iron core tooth 2 is set
It is equipped with outside winding 8.The rotor core tooth 5 of internal rotor 7 forms teeth groove dislocation arrangement mode with the stator iron core tooth 2 of external stator 1.
Armature winding 4 circulates the power supply of connection out of phase successively.Outside winding 8 is arranged on the rear portion of stator iron core tooth 2
In stopper slot；Spacing slot structure is trapezium structure wide outside and narrow inside.
Utility model works process is as follows：
In Fig. 2, when the magnetic field that the indirect current of armature winding 8 is formed and the magnetic field of permanent magnet 3 form resultant field, rotor exists
During 1 position, the magnetic field that A phases armature winding 41 is formed is consistent with the magnetic direction of permanent magnet 3, and resultant field is enhanced magnetic field, promotees
Rotor core tooth 9 at A phases armature winding 41 is set to be rotated to A phases armature winding 41, when rotor core tooth 9 corresponds to position close to teeth groove
Put, magnetic field is weaker.And the sense of current is reverse at this moment, resultant field further weakens.B phases armature winding 42 is powered simultaneously, together
Sample promotes the groove of B phases armature winding 42, and nearby rotor core tooth 9 is close to its, promotes rotor core tooth 9 to rotate.In this way, it is all
And renew, A, B, C phase armature winding pass to alternating current in turn, promote rotor core tooth 9 constantly to rotate, then defeated by shaft end
Go out.
In motor rotary course, the resultant field of formation a, part rotates for internal rotor 7, and another part passes through
Remaining leakage field part is utilized externally output by armature winding 4, external stator 1 with the similar transformer combination that outside winding 8 is formed.
When being connected with alternating current in this electric machine structure armature coil 4, external stator 1（Equivalent to iron core）In just produce AC magnetism
It is logical, make to induce voltage in outside winding 8（Or electric current）, transformer principle as shown in Figure 3, thus leakage field part is re-used
As power generation application, powered after a series of adjustment such as rectifying and wave-filtering voltage stabilizing to whole system, improve magnetic field utilization rate, avoid
Consumption wastes.
