Description
Technical field
The invention belongs to become magnetic flux reluctance motor field, more particularly, to a kind of coiling machine for becoming magnetic flux reluctance motor
Structure, it can be applied to the change magnetic flux reluctance motor field with double-stator structure.
Background technology
Become magnetic flux reluctance motor to have many advantages：1. not needing permanent-magnet material, the cost of motor can be substantially reduced；②
Exciting Windings for Transverse Differential Protection is on stator, it is not necessary to slip ring and brush, can improve the stability of motor；3. there is no winding and permanent magnetism on rotor
Body, it is very suitable for high-speed cruising；4. armature winding and Exciting Windings for Transverse Differential Protection are concentratred windings, winding overhang length can be reduced,
Material is saved, improves power density.But traditional single stator becomes magnetic flux reluctance motor, due to have on stator a set of armature around
Group and set of excitation winding, and armature winding use Double Layer Winding to reduce harmonic wave more so that contain in a groove three layers around
Group, thus groove area is bigger, is also not easy to motor inserting-coil, and insulation material is also had additional between armature and Exciting Windings for Transverse Differential Protection
Material, reduces groove utilization rate.Meanwhile for given stator outer diameter, big groove area can reduce air-gap diameter, and then reduce electricity
The output torque of machine.
The content of the invention
For the disadvantages described above or Improvement requirement of prior art, the invention provides a kind of winding for becoming magnetic flux reluctance motor
Mechanism, its object is to which armature winding is separated with Exciting Windings for Transverse Differential Protection, it is difficult thus to solve motor inserting-coil, without armature and excitation around
Insulating materials is set up between group, improves groove utilization rate.
To achieve the above object, according to one aspect of the present invention, it is proposed that one kind is used for bimorph transducer and becomes magnetic flux magnetic resistance electricity
The winding mechanism of machine, it is characterised in that the bimorph transducer, which becomes magnetic flux reluctance motor, to be had coaxially connected and offer identical slot number
The first stator 1 and the second stator 2, wherein Exciting Windings for Transverse Differential Protection 4 and armature winding 5 be arranged separately on first stator 1 and described
In the groove of second stator 2, the Exciting Windings for Transverse Differential Protection (4) separates with the armature winding (5), between be not provided with insulating materials.
Further, first stator 1 and second stator 2 have radially coaxial connection and axially coaxially connected two
Kind mode.
Further, when first stator 1 and second stator 2 have radially coaxial connection, the armature around
Group 5 is arranged in the groove of the stator in coaxial outside.
In general, by the contemplated above technical scheme of the present invention compared with prior art, due to armature winding with
Exciting Windings for Transverse Differential Protection separates, and can solve motor inserting-coil hardly possible, without setting up insulating materials between armature and Exciting Windings for Transverse Differential Protection, to improve groove
Utilization rate.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.As long as in addition, technical characteristic involved in each embodiment of invention described below
Conflict can is not formed each other to be mutually combined.
Below in conjunction with the accompanying drawings, the implementation of winding connection is illustrated.
Change magnetic flux reluctance motor of the present invention has two stators 1 and 2.As illustrated in fig. 1 and 2, magnetic flux is respectively become
Reluctance motor is the installation situation in the case of axially and radially, wherein, stator 1 and stator 2 have 6 grooves, coaxially connected.Excitation
Winding 4 is arranged in first stator 1, and armature winding 5 is arranged in second stator 2 according to the pole of three-phase 4.
The conventional winding construction for becoming magnetic flux magnetic resistance Double-stator motor is to arrange set of excitation winding 4 on two stators
With a set of armature winding 5, because armature winding more than 5 uses Double Layer Winding, thus contain three layers of winding in a stator slot, and
Insulation is set between Exciting Windings for Transverse Differential Protection 4 and armature winding 5.The present invention and the difference of conventional winding construction are：1. Exciting Windings for Transverse Differential Protection 4
Be arranged in first stator 1, armature winding 5 is arranged in second stator 2, thus comprised only in the groove of stator 1 two layers around
Group, and Single-layer Windings are comprised only in the groove of stator 2, it is easier to motor inserting-coil；2. because Exciting Windings for Transverse Differential Protection 4 separates with armature winding 5,
Thus groove utilization rate is improved, while alternate break down can also be reduced without insulation between Exciting Windings for Transverse Differential Protection 4 and armature winding 5
Probability.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, all any modification, equivalent and improvement made within the spirit and principles of the invention etc., all should be included
Within protection scope of the present invention.
