Abstract

The utility model discloses a motor rotor body structure with permanent magnets and magnetic-conduction groove bodies. The motor rotor body structure includes the permanent magnets, the magnetic-conduction groove bodies and a rotor body fixed on a motor shaft; a plurality of magnetic-conduction groove bodies are embedded on the periphery of the rotor body along the axial direction; the embedded ends of the magnetic-conduction groove bodies are matched with the shape of grooves of the rotor body; and the permanent magnets are arranged in grooves at the other ends of the magnetic-conduction groove bodies. The motor rotor body structure with the permanent magnets and the magnetic-conduction groove bodies of the utility model is advantageous in simple and reasonable structure. With the motor rotor body structure adopted, the problem of infirmness of permanent magnets and the problem that the permanent magnets are prone to falling off from a rotor body in the prior art can be effectively solved, and the demagnetization of the permanent magnets can be avoided; the performance of a motor can be more stable and reliable; the efficiency of the motor can be improved; the service life of the motor can be prolonged; cost is low; the motor can be applicable to a wider range; and great economic benefit and social benefits can be realized.

Description

A kind of rotor body structure of motor with permanent magnetism and magnetic conduction
Technical field
The utility model relates to a kind of structure of motor rotor, particularly relates to a kind of rotor body structure of motor with permanent magnetism and magnetic conduction.
Background technology
Along with domestic electric machine industry is in development, rotor band magnetic is also more widely by, application, and the motor product of rotor banding magnetic, owing to carrying magnetic, makes product more energy-conservation, and torque is adaption demand more, and volume reduces.But due to the overladen appearance of torque and load, make permanent magnet produce demagnetization, can not meet motor and work under complicated situation, therefore had a strong impact on using and promoting of this kind of motor.
Summary of the invention
The problem that the utility model exists for prior art, provides a kind of applied widely, simple and reasonable for structure, and motor stabilizing is good, motor precision is high, function admirable is reliable, with low cost, guarantees a kind of rotor body structure of motor with permanent magnetism and magnetic conduction that permanent magnet does not demagnetize.
The purpose of this utility model realizes by the following technical solutions:
A rotor body structure of motor with permanent magnetism and magnetic conduction, comprising: permanent magnetic strip, magnetic conduction cell body and be fixed on the rotor block on motor shaft, and it is: some magnetic conduction cell bodies are inlayed on axially in rotor block outer ring; The flute profile that this magnetic conduction cell body is inlayed one end and rotor block is suitable, in the groove of the other end of described magnetic conduction cell body, is provided with permanent magnetic strip.
The cross sectional shape of described rotor block is circle or polygon.
The utility model is compared with prior art owing to having adopted permanent magnetic strip to be located in magnetic conduction cell body, and magnetic conduction cell body is embedded on permanent magnet, both effectively solve the problem that in prior art, permanent magnet is insecure and permanent magnet easily comes off from rotor block, effectively solved again the phenomenon of permanent magnet demagnetization.The utility model is simple and reasonable for structure, and motor performance is more stable, more reliable, and electric efficiency improves, and longer service life, with low cost, makes the motor scope of application wider, has good economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a kind of execution mode of the present utility model.
In figure: permanent magnetic strip 1, magnetic conduction cell body 2, motor shaft 3, rotor block 4.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail; but protection range of the present utility model is not limited by specific embodiment; with claims, be as the criterion; in addition; under the prerequisite without prejudice to technical solutions of the utility model, within any change that those of ordinary skills that the utility model is made easily realize or change can fall into claim scope of the present utility model.
Embodiment 1
The cross-section structure signal of a kind of execution mode of a kind of rotor body structure of motor with permanent magnetism and magnetic conduction of the utility model as shown in Figure 1, there is shown, comprise: permanent magnetic strip 1, magnetic conduction cell body 2 and be fixed on the rotor block 4 on motor shaft 3, its cross section is that some magnetic conduction cell bodies 2 are inlayed on axially in polygonal rotor block 4 outer rings; It is suitable that this magnetic conduction cell body 2 is inlayed the flute profile of one end and rotor block 4, in the groove of the other end of described magnetic conduction cell body 2, is provided with permanent magnetic strip 1.
Embodiment 2
Cross section is that some magnetic conduction cell bodies 2 are inlayed on axially in circular rotor block 4 outer rings.The other the same as in Example 1.
