Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like figure 1 A rotor device of a permanent magnet motor, including a hub 1, which is different in that: the periphery of the hub 1 is bonded with a ring-shaped silicon steel sheet 2, which satisfies the firm combination of the two. At the same time, considering the normal operation needs, several permanent magnets 3 are distributed on the upper end of the annular silicon steel sheet 2 . In order to satisfy stable installation, a positioning component is arranged between the permanent magnet 3 and the annular silicon steel sheet 2 . Moreover, in order to carry out stable positioning, the permanent magnet 3 is covered with a magnetic steel end plate 4 . Considerin...

Abstract

The invention relates to a rotor device of a permanent magnet motor. The rotor device comprises a hub, an annular silicon steel sheet is adhered to the periphery of the hub, a plurality of permanent magnets are distributed at the upper end of the annular silicon steel sheet, a positioning assembly is arranged between the permanent magnets and the annular silicon steel sheet, a magnetic steel end plate covers the permanent magnets, and a positioning assembly is arranged between the magnetic steel end plate and the annular silicon steel sheet. Therefore, the hub and the annular silicon steel sheet can be adhered through glue, and stable combination of the hub and the annular silicon steel sheet is met. And the bolt is used for locking and limiting, so that the requirement of stable integral combination can be met, abnormal displacement during use is avoided, and the use effect is ensured. Even if the glue fails, auxiliary locking can be carried out. The arrangement of the permanent magnets is more compact and reasonable, and a better using effect can be achieved. The overall structure is simple, the hub can be manufactured in a casting mode, and effective light weight is achieved under the condition that the structural strength is guaranteed. The assembly and the use are convenient, and the universality is better.

Description

technical field [0001] The invention relates to a rotor device, in particular to a permanent magnet motor rotor device. Background technique [0002] At present, the permanent magnet motor rotor has a wide range of applications, especially in the fields of machine tools and vehicle manufacturing. However, the existing rotor has a complicated structure, and the combination is often realized through the interference fit of the parts and the screw as an auxiliary limit. After a long time of use, it is easy to loosen, which will affect the stable operation of the rotor. [0003] At the same time, the existing rotor cores need to be driven by keys, and the interference press-fitting between the core and the rotating shaft is prone to damage to parts. [0004] In view of the above-mentioned defects, the designer actively researches and innovates in order to create a permanent magnet motor rotor device to make it more industrially useful. Contents of the invention [0005] In ...
