Description
Technical field
The utility model relates to p-m rotor field, more specifically, relates to a kind of new structure of permanent magnetism rotor with non-salient poles.
Background technology
Along with permanent magnetic material performance improve constantly and perfect, the particularly thermal stability of Nd-Fe-B permanent magnetic and the improvement of corrosion resistance, and the further developing and improving of power electronic element, the purposes of magneto is also more and more extensive.Permanent magnet, as metal material, directly contacts with air and easily produces oxidation.Once oxidation, the performance of motor can be had a strong impact on.Therefore, how improving the corrosion resistance of permanent magnet in motor is improve the key of motor reliability.
In the new structure of the high speed rotor shafts of Turbocorp Ltd's invention, provide a kind of axle sleeve, ensure motor at high speeds permanent magnet can not to dish out armature spindle and cause structure to be separated.This scheme, ensure that motor when High Rotation Speed have very large centrifugal force, the splitting of permanent magnet can not be caused, disintegrate.
The utility model, on above-mentioned patent basis, proposes the reliable improvement of further a kind of servo motor rotor structure, realizes protecting further rotor permanent magnet, strengthen and protect the sealing of permanent magnet, extends the useful life of motor.
Utility model content
The purpose of this utility model is to provide a kind of servo motor rotor structure reliably to improve, and realizes the optimization to rotor spindle structure, improves the sealing of permanent magnet, weakens permanent magnet and directly contact caused oxidation with air, extends physical life.
The utility model provides a kind of new structure of permanent magnetism rotor with non-salient poles, comprising: the motor shaft shoulder, gimbal, permanent magnet, stainless steel sleeve, yoke, anti-corrosion material, and welding end surface.
Preferably, the external diameter of the wherein said motor shaft shoulder and gimbal all extends to the outer radius of permanent magnet.
Preferably, the length of wherein said stainless steel sleeve 1 extends to the outer rim covering the motor shaft shoulder, gimbal, thus to the complete envelope of permanent magnet.
Preferably, the outer round surface of wherein said permanent magnet smears anti-corrosion material, thus the area that minimizing permanent magnet directly contacts with extraneous air.
Preferably, wherein after hot charging stainless steel sleeve and gimbal, the ring that stainless steel sleeve and motor shaft shoulder peace weighed welds, and forms welding end surface, thus does not interspace in junction.
The utility model feature is as follows:
(1) effectively enhance the sealing of permanent magnet is protected, reduce permanent magnet and directly contact caused oxidation with air, extend the useful life of motor;
(2) effectively stop the axial endplay of permanent magnet, yoke, enhance the reliability of motor.
This technical scheme, compared with existing domestic and international existing scheme, achieves the available protecting to servomotor permanent magnet, and structure is simple, good reliability.
Accompanying drawing explanation
To be described the utility model by reference to the accompanying drawings now.
Fig. 1 is highly reliable servo motor rotor architecture advances schematic diagram.
Wherein, 1 stainless steel sleeve; 2 permanent magnets; 3 yokes; 4 improve back balance ring; 5 improve the rear shaft shoulder; 6 welding end surface; 7 anti-corrosion materials.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
Fig. 1 is highly reliable servo motor rotor architecture advances schematic diagram.Expand the motor shaft shoulder 5 and the external diameter of gimbal 4, make it all can extend to the outer radius of permanent magnet, extend the length of stainless steel sleeve 1, until cover the outer rim of the shaft shoulder, gimbal, thus reach the complete envelope to permanent magnet 2.Before installation stainless steel sleeve 1, first to carry out preservative treatment to the cylindrical of permanent magnet, namely at its surface smear anti-corrosion material 7, thus the area that minimizing permanent magnet directly contacts with extraneous air, improve corrosion resistance.After stainless steel sleeve 1, gimbal 4 are installed respectively, respectively after hot charging, stainless steel sleeve 1 are welded with the shaft shoulder 5, gimbal 4 respectively, form welding end surface 6, thus do not interspace in junction, to protect permanent magnet further, improve its corrosion resistance.
