Description

Novel motor stator and rotor structure

Technical Field

The utility model belongs to the technical field of the motor, specifically relate to a novel motor stator-rotor structure.

Background

The conventional common structure of the motor is generally a radial stator structure, an axial stator structure and the like, is limited by the material characteristics of the motor, is difficult to further improve the power density and the torque density of the motor, cannot meet the actual requirements under the condition of limited installation space, and causes the bottleneck of technical development.

Disclosure of Invention

Aiming at the problems, the utility model makes up the defects of the prior art and provides a novel motor stator and rotor structure; the utility model discloses a neotype stator-rotor structure can improve the power density and the torque density of motor to can be at reduce cost under the condition with the output.

In order to achieve the above purpose, the utility model adopts the following technical scheme.

The utility model provides a novel motor stator-rotor structure, stator core and rotor mechanism including the cooperation use, a serial communication port, rotor mechanism includes the spider, the spider has the annular groove, be provided with radial outer permanent magnet, radial interior permanent magnet and axial permanent magnet in the annular groove, stator core places for the annular fit among the annular groove, be provided with on the stator core with the radial outer processing groove that radial outer permanent magnet corresponds, with radial interior processing groove that radial interior permanent magnet corresponds, with the axial processing groove that axial permanent magnet corresponds round radial outer processing groove with the coil has been inlayed in the axial processing groove.

Further, an electromagnetic gap is reserved between the stator core and the rotor mechanism.

Further, the radial outer permanent magnet, the radial inner permanent magnet and the axial permanent magnet are fixed in the annular groove of the rotor support in a mechanical fixing or bonding mode.

Further, the stator core is a magnetic silicon steel sheet.

The beneficial effects of the utility model.

The utility model discloses a three permanent magnet is as main rotor, stator core of sharing under same volume the utility model discloses a motor under the structure can be equivalent to the power of three motor, has improved power density, and when the rotational speed is permanent, power density has also bigger thereupon greatly torque density to need still less material under the prerequisite of same power design, the cost is reduced.

Drawings

In order to make the technical problem, technical scheme and beneficial effect that the utility model solved more clearly understand, it is right to combine the attached drawing and detailed description mode below the utility model discloses further detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Fig. 1 is a schematic side view of the present invention.

Fig. 2 is a schematic view of the rotor mechanism of the present invention.

Fig. 3 is a schematic view of a stator core of the present invention.

Fig. 4 is an enlarged schematic view of fig. 3 a according to the present invention.

The labels in the figure are: the stator comprises a stator core 1, a rotor support 2, an annular groove 3, a radial outer permanent magnet 4, a radial inner permanent magnet 5, an axial permanent magnet 6, a radial outer processing groove 7, a radial inner processing groove 8, an axial processing groove 9 and a coil 10.

Detailed Description

The combined type stator structure comprises a stator core 1 and a rotor mechanism which are matched with each other, wherein the rotor mechanism comprises a rotor support 2, the rotor support 2 is provided with an annular groove 3, a radial outer permanent magnet 4, a radial inner permanent magnet 5 and an axial permanent magnet 6 are arranged in the annular groove 3, and the radial outer permanent magnet 4, the radial inner permanent magnet 5 and the axial permanent magnet 6 are fixed in the annular groove 3 of the rotor support 2 in a mechanical fixing or bonding mode.

The stator core 1 is annularly arranged in the annular groove 3 in a matching mode, the stator core 1 is coaxial with the rotor support 2, a radial outer processing groove 7 corresponding to the radial outer permanent magnet 4, a radial inner processing groove 8 corresponding to the radial inner permanent magnet 5 and an axial processing groove 9 corresponding to the axial permanent magnet 6 are arranged on the stator core 1, and a coil 10 is embedded around the radial outer processing groove 7, the radial inner processing groove 8 and the axial processing groove 9.

The stator core 1 is a magnetic silicon steel sheet. An electromagnetic gap is reserved between the stator core 1 and the rotor mechanism.

Rotor bracket 2 and stator core 1 are with the axle center and rotate, and when rotor bracket 2 rotatory back that gets up, three permanent magnet played the effect of rotor simultaneously to a shared stator core 1, under same volume the utility model discloses the power of a motor under the structure can be equivalent to three motor has improved power density, and when the rotational speed is permanent, power density has big torque density also bigger thereupon to need still less material under the prerequisite of same power design, the cost is reduced.

When the rotor mechanism normally operates, the rotor mechanism is a rotating body, magnetic fields emitted by the radial outer permanent magnet 4, the radial inner permanent magnet 5 and the axial permanent magnet 6 pass through the stator core 1 and then return to the rotor support 2 to be closed, so that the magnetic fields generated by current in the coil 10 interact with each other to generate electromagnetic force, and expected output power is achieved.

It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
