Embodiment 1

[0031] Such as Figure 3 to Figure 5 As shown, Embodiment 1 of the present invention provides a mover structure. The mover structure includes a mover body 10, and the mover body 10 includes a mover inner ring structure 12 and a mover outer ring structure 11; the mover outer ring structure 11 is located on the outer periphery of the mover inner ring structure 12, and the mover inner ring structure 12 Set separately from the mover outer ring structure 11, wherein the mover outer ring structure 11 is made of the first silicon steel sheet, the thickness of the first silicon steel sheet is greater than or equal to 0.05mm and less than or equal to 0.25mm; the permanent magnet 40 is arranged on the mover On the sub-outer ring structure 11.

[0032] In the present invention, the mover main body 10 is set as two parts, the mover inner ring structure 12 and the mover outer ring structure 11, and the mover outer ring structure 11 is made of the first silicon steel sheet with a thickness...

Embodiment 2

[0073] The difference between embodiment two and embodiment one is: as Image 6 As shown, in the second embodiment of the present invention, when there are two installation grooves 111, there is an included angle between the two installation grooves, so that the installation groove group has a V-shaped structure. Specifically, such as Image 6 As shown, the adjacent mounting grooves 111 are arranged at intervals, the open end of the V-shaped structure faces the outer edge of the outer ring structure 11 of the mover, and the pointed end of the V-shaped structure faces the side where the inner ring structure 12 of the mover is located.

[0074] Other structures of the second embodiment are the same as those of the first embodiment, and will not be repeated here.

Abstract

The invention provides a rotor structure and a motor having the rotor structure. The rotor structure comprises a rotor body. The rotor body comprises a rotor inner ring structure; a rotor outer ring structure which is arranged at the periphery of the rotor inner ring structure, wherein the rotor inner ring structure and the rotor outer ring structure are separately arranged, the rotor outer ring structure is manufactured by first silicon steel sheets, and the thickness of each first silicon steel sheet is greater than or equal to 0.05mm and less than or equal to 0.25mm; and permanent magnets which are arranged on the rotor outer ring structure. With application of the technical scheme, the motor efficiency can be enhanced.

Description

technical field [0001] The invention relates to the field of motors, in particular to a mover structure and a motor having the same. Background technique [0002] As human life becomes more and more intelligent, the performance and reliability requirements of motors in various fields are getting higher and higher, and the demand is increasing. Various motor manufacturers are striving to develop motor products with high efficiency, high reliability and low cost. [0003] figure 1 with figure 2 It is a structural schematic diagram of a motor in the prior art. Such as figure 1 As shown, the motor includes a mover body 10' and a stator structure sleeved on the outer periphery of the mover body 10'. The mover body 10' is provided with a mounting groove 111' for installing a permanent magnet 40', and the stator mechanism includes a stator body 20' and the stator winding 21', the mover body 10' is provided with an axial through hole 30' for installing a rotating shaft. The m...
