Description
Technical field
This utility model relates to a kind of high speed permanent magnet motor rotor punching, belongs to technical field of motors.
Background technology
At present, the Chinese patent of Publication No. CN202103503U discloses a kind of magnetic-shoe built-in permanent-magnetic motor rotor,
It proposes a kind of rotor sheet of permanent magnet motor, it is characterized in that rotor punching with multiple square slotted eyes and screw hole, due to electricity
The applied voltage of machine is usually fixing, and when back-emf is more than applied voltage, continuing to improve motor speed will be restricted,
And the magnet steel arrangement of the disclosure patent is suitable for more slow-revving magneto, and it is not suitable for the Permanent Magnet and Electric that rotating speed is higher
Machine.
Summary of the invention
Technical problem to be solved in the utility model is to overcome prior art defect, it is provided that a kind of high-speed permanent magnet motor turns
Sub-punching, it is applicable to high-speed permanent magnet motor, and deformation when can absorb high-speed permanent magnet motor action, thus is conducive to carrying
The high machining accuracy using this high-speed permanent magnet motor equipment and working (machining) efficiency.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of high speed permanent magnet motor rotor punching,
It includes body, and described body has:
Multiple radial permanent magnet body grooves, described radial permanent magnet body groove being radially arranged along described body, adjacent radial direction is forever
Forming teeth portion between magnet slot, the inside angle part at described radial permanent magnet body groove is provided with dilatancy absorption cell.
Further, described body be provided centrally with axis hole.
Further, described body is provided with magnet isolation tank on position between described teeth portion and described axis hole.
Further, described magnet isolation tank is circular hole structure.
Further, described dilatancy absorption cell and described magnet isolation tank constitute overall magnetic shielding structure.
Further for avoiding stress to concentrate, change the force-bearing situation of rotor core, at the laterior horn of radial permanent magnet body groove
Portion is provided with stress dispersion slot, and described stress dispersion slot extends a distance into towards the teeth portion being adjacent to.
Further, described dilatancy absorption cell is arcuate structure.
Further, described dilatancy absorption cell is the large semicircle cavernous structure being connected with radial permanent magnet body groove.
After have employed technique scheme, the radial permanent magnet body groove of rotor punching of the present utility model is along the radial direction of its body
Arrange, add direct-axis synchronous inductance, by weakening air-gap field, improve magneto rotating speed, and owing to this punching is used for
High-speed permanent magnet motor, the centrifugal force that the permanent magnet in radial permanent magnet body groove is subject to is relatively big, thus deformation is relatively big, and magneto runs
Producing loss, cause motor component, produce dilatancy including permanent magnet, dilatancy absorption cell can absorb because of centrifugal force
The deformation produced with thermal expansion, makes permanent magnet avoid because deformation is impaired, and stress dispersion slot is designed as circular arc and seamlessly transits, it is to avoid
Stress is concentrated, and is conducive to improving the force-bearing situation of rotor core.
