Abstract
The utility model discloses a table pastes formula permanent -magnet machine utmost point magnetic shoe structure to one side, including rotor core, location magnet steel and non - location magnet steel, rotor core passes through the rivet riveting by a plurality of sections rotor punchings and constitutes be equipped with a plurality of location magnet steel and non - location magnet steel on rotor core's the surface, location magnet steel and non - location magnet steel are crisscross to distribute in rotor core's surface, set up on the internal surface of location magnet steel fluted, rotor punching and location magnet steel correspond that the position is equipped with and the arch that the recess corresponds, the central line of recess constitutes first error angle with the central line of location magnet steel, the central line of bellied central line and rotor punching constitutes the second error angle, the angle sum of first error angle and second error angle equals the design dislocation angle of magnetic shoe. The utility model discloses an add the recess on the magnet steel of location, and the groove phase satisfies the designing requirement to angle of central line dislocation to the poststack.
Description
Technical field
The utility model relates to magneto field, specifically, is related specifically to a kind of surface-mounted permanent magnet machine oblique pole magnetic shoe structure.
Background technology
Magneto, when eliminating torque pulsation, needs, by magnetic shoe levels dislocation certain angle, to reduce cogging torque, improve motor precision.Industry is generally by motor mandrel adds keyway, and levels magnetic shoe oppositely to folded, reaches the dislocation angle of designing requirement.The defect of this scheme is: processing cost is higher, and can increase dynamically balanced degree of unbalance, on group of motors, impact is housed.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides a kind of surface-mounted permanent magnet machine oblique pole magnetic shoe structure, to solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of surface-mounted permanent magnet machine oblique pole magnetic shoe structure, comprises rotor core, positioning magnetic steel and non-locating magnet steel, described rotor core is consisted of rivet some sections of rotor punchings, the outer surface of described rotor core is provided with some positioning magnetic steel and non-locating magnet steel, described positioning magnetic steel and non-locating magnet steel are interspersed in the outer surface of rotor core, the inner surface of positioning magnetic steel offers groove, the projection corresponding with described groove is provided with the correspondence position of positioning magnetic steel at rotor punching, the center line of described groove and the center line of positioning magnetic steel form the first error angle, the center line of described projection and the center line of rotor punching form the second error angle, the angle sum of described first error angle and the second error angle equals the design dislocation angle of magnetic shoe.
Compared with prior art, the beneficial effects of the utility model are as follows:
By adding groove in positioning magnetic steel, and groove is relative to misalignment angle, meets design requirement to poststack.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of surface-mounted permanent magnet machine described in the utility model oblique pole magnetic shoe structure.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Number in the figure illustrates: rotor core 1, positioning magnetic steel 2, non-locating magnet steel 3.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
See Fig. 1, the oblique pole of a kind of surface-mounted permanent magnet machine described in the utility model magnetic shoe structure, comprises rotor core 1, positioning magnetic steel 2 and non-locating magnet steel 3, described rotor core 1 is consisted of rivet some sections of rotor punchings, the outer surface of described rotor core 1 is provided with some positioning magnetic steel 2 and non-locating magnet steel 3, described positioning magnetic steel 2 and non-locating magnet steel 3 are interspersed in the outer surface of rotor core, the inner surface of positioning magnetic steel 2 offers groove, the projection corresponding with described groove is provided with the correspondence position of positioning magnetic steel 2 at rotor punching, the center line of described groove and the center line of positioning magnetic steel 2 form the first error angle, the center line of described projection and the center line of rotor punching form the second error angle, the angle sum of described first error angle and the second error angle equals the design dislocation angle of magnetic shoe.
Feature of the present utility model is to add groove in positioning magnetic steel, and groove is relative to misalignment angle, meets design requirement to poststack.Such as: designing requirement levels magnet steel misplaces 5 °, then magnet steel recessing (groove is counterclockwise 2.5 °), projection opened by rotor punching, just coordinate, and all rotate 2.5 ° relative to center line, then go up lower magnetic steel to folded, become one counterclockwise one clockwise to folded, levels just dislocation 5 ° altogether, reach design objective, because the design is recessing on magnet steel, magnet steel cost can not be increased, rotor core is punch forming, does not affect cost.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
