Problems solved by technology

[0002] In the existing built-in permanent magnet synchronous motor, the rotor punching is made by the process of full-circle blanking and punching the magnetic steel groove. Although the rotor punching produced by this process has good integrity, the manufacturing process requires high requirements, and after errors It is scrapped as a whole, and the consumption is relatively large, so it needs to be improved urgently

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] This preferred embodiment is Figure 4 and 5 Shown is a permanent magnet motor assembly rotor, including such as image 3 The rotor yoke shown and the permanent magnets installed on the rotor yoke; the rotor yoke is composed of multiple such as figure 2 The laminated block 6 of the same assembly unit shown is formed by interlocking and inserting the concave and convex platforms on both sides. Assembled unit laminating block 6 is made of such as figure 1 The rotor punching assembly unit shown is formed by laminating the self-rivet k on its main body, the number and position of the self-rivet k can be set according to the size of the rotor; the rotor punching assembly unit includes a ring-shaped assembly The main body of the unit and the main body of the assembled unit are symmetrically provided with two magnetic steel grooves b exte...

Abstract

The invention discloses a permanent magnet motor rotor punching sheet assembling unit and an assembled rotor. Multiple assembling units are laminated to form blocks through self-pierce rivets, assembling unit laminated blocks are assembled with other same assembling unit laminated blocks through left-side bosses and right-side bosses of the assembling units so as to form an annular rotor magnet yoke. The permanent magnet motor rotor punching sheet assembling unit and the assembled rotor have the advantages that the size of the assembling unit is small, requirements of the manufacturing technique are relatively lower, a failure to manufacture the rotor punching sheet assembling unit will not cause scrapping of overall rotor punching sheets, and wastes can be largely reduced.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a permanent magnet motor rotor punching assembly unit and an assembled rotor. Background technique [0002] In the existing built-in permanent magnet synchronous motor, the rotor punching is made by the process of full-circle blanking and punching the magnetic steel groove. Although the rotor punching produced by this process has good integrity, the manufacturing process requires high requirements, and after errors It is invalid as a whole, and the consumption is relatively large, which needs to be improved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a permanent magnet motor rotor punching assembly unit with low manufacturing process requirements and less loss in the manufacturing process. [0004] The technical solution adopted by the present invention to solve the above-mentioned techn...
