Abstract

The invention discloses a stator module of a permanent magnet motor. The stator module comprises a spindle, a stator frame fixedly connected with the spindle and a plurality of groups of independent iron core units with the same structure uniformly distributed on the stator frame, wherein each group of independent iron core unit comprises an independent iron core connected with the stator frame and a magnet winding coil arranged on the independent iron core. By adopting the structure, a plurality of groups of independent iron core units are uniformly distributed on the disc-shaped frame along the circumference to form stator windings, after each independent iron core unit winding is powered on, both ends of the independent iron core can form N and S independent magnetic fields, the torque formed is greater than that of the motor in the prior art, the working efficiency of the motor can be improved, and the energy consumption is reduced.

Description

A kind of stator module of magneto

Technical field

The invention belongs to field of motor manufacturing, be specifically related to a kind of stator module of magneto.

Background technology

Along with global energy crisis day by day approaches, the use cost of non-renewable energy resources such as oil, natural gas constantly increases, and electric vehicle motor and Research on Driving System and application have become the trend of energy development.At present in the known technology, the stator core of the stator module of magneto is generally made by silicon steel sheet, and its structure is to offer semi-enclosed slot on silicon steel sheet, produces magnetic field at the fluting end behind the stator winding electrifying, rotor obtains torque and rotates under the effect in this magnetic field.Stator core unslotted end is that integral body links together, and there is the phenomenon of cancelling out each other in the magnetic field of generation, thereby greatly reduces the operating efficiency of motor, and energy consumption is bigger.

Summary of the invention

Technical problem to be solved by this invention is: a kind of stator module of magneto is provided, and the stator module of this kind magneto can improve motor working efficiency, cuts down the consumption of energy.

Solve this technical problem, technical scheme of the present invention is: a kind of stator module of magneto, described stator module comprises main shaft, with the affixed stator support of main shaft, be distributed in the independent iron core unit of the many groups same structure on the stator support, described every group of independence iron core unit comprises the independent iron core that is connected with stator support and the electromagnetism winding coil on the independent iron core.

Described stator support is the disk-shaped bracket that is fixed in the main shaft middle part.

The periphery of described disk-shaped bracket has the radial extension bar identical with independent iron core unit quantity, described every group of independence iron core unit comprises fixed strip, rivet and the electromagnetism winding coil of iron core piece, iron core piece one side, described rivet passes the extension bar of fixed strip, iron core piece and disk-shaped bracket successively, and described electromagnetism winding coil is around on extension bar, iron core piece and the fixed strip of disk-shaped bracket.

Described iron core piece is " I " shape.

The stator module of a kind of magneto of the present invention adopts such structure, on disk-shaped bracket, form stator winding by many groups of independent iron core unit by circumference uniform distribution, the two ends of each independent iron core in independent iron core unit winding energising back promptly produce N and the bipolar individual magnetic of S, make the torque force of the torque force of generation greater than the prior art motor, can improve motor working efficiency, cut down the consumption of energy.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of magneto, comprise stator module, rotor support body, external rotor 6 and internal rotor 8, rotor support body, external rotor 6 and internal rotor 8 are connected as a single entity, have air gap between the outer round surface of the stator core of stator module and external rotor 6 internal circular surfaces, have air gap between the internal circular surfaces of the stator core of stator module and internal rotor 8 outer round surface.Stator module comprises main shaft 1, the stator support affixed with main shaft 1, be distributed in the independent iron core unit 7 of the many groups same structure on the stator support, stator support is the disk-shaped bracket 4 that is fixed in main shaft 1 middle part, the periphery of disk-shaped bracket 4 has the radial extension bar identical with independent iron core unit 7 quantity, every group of independence iron core unit 7 comprises iron core piece 15, the fixed strip 11 of iron core piece 15 1 sides, cylinder rivet 12 and electromagnetism winding coil 13, iron core piece 15 is " I " shape, cylinder rivet 12 passes fixed strip 11 successively, the extension bar of iron core piece 15 and disk-shaped bracket 4, electromagnetism winding coil 13 is around in the extension bar of disk-shaped bracket 4, on iron core piece 15 and the fixed strip 11, place pad 14 between the extension bar of iron core piece 15 and disk-shaped bracket 4.The rotor support body is made up of the first rotor support 5 and second rotor field spider 9, external rotor 6 is fixed between the first rotor support 5 and second rotor field spider 9, the internal rotor 8 and second rotor field spider 9 are affixed, the first rotor support 5 and second rotor field spider 9 are respectively arranged with the centre bore of placing bearing 2, and bearing 2 is placed on the main shaft 1.

When electrical power, independent iron core unit 7 produces N and S two magnetic pole individual magnetic, and external rotor and internal rotor rotate under the action of a magnetic field power of two magnetic pole stators, the torque that produces can improve motor working efficiency much larger than common magnetic field motor, cuts down the consumption of energy, energy-conserving and environment-protective, long service life.
