Embodiment 1

[0034] Such as figure 1 As shown, the surface-mounted permanent magnet synchronous motor magnetic steel seamless assembly device includes a positioning part and a pressing part. The positioning part is a hollow metal outer ring 1, and the metal outer ring 1 is concentric with the rotor core 8. , the metal outer ring 1 is fixedly installed on the magnetic isolation strip 7 of the rotor core 8 through fastening bolts 3, the pressing part is an arc plate 2, and the arc plate 2 is concentric with the metal outer ring 1, and the The arc plate 2 is attached to the inner side of the metal outer ring 1 in the radial direction, and the two are flexibly connected by pins 4. The magnetic steel 6 is installed between the arc plate 2 and the rotor core 8. The metal outer ring 1 is There are threaded holes in the radial direction, and transmission bolts 5 are arranged in the threaded holes to withstand the arc plate.

[0035] As a further implementation of this embodiment, a return spring ...

Embodiment 2

[0037] The difference between embodiment 2 and embodiment 1 is that the transmission parts between the metal outer ring 1 and the arc plate 2 are different. In embodiment 1, bolts are used. A bearing is provided, the bearing is embedded in the back of the arc plate 2, one end of the screw passes through the threaded hole provided on the metal outer ring 1 and is fixed in the center of the bearing, and the other end of the screw is provided with a handle , so that the advance and retreat of the arc plate can be directly controlled by rotating the handle.

[0038] The magnet seamless assembly process of the surface-mounted permanent magnet synchronous motor utilizing the above magnet seamless assembly device includes the following steps:

[0039]S11. Install the positioning part, pressing part and transmission part on the rotor core, and adjust the distance between the pressing part and the rotor core so that it is consistent with the thickness of the magnetic steel or 1-3mm gre...

Abstract

The invention relates to a surface-mounted permanent magnet synchronous motor magnetic steel seamless assembling apparatus, and an assembling and repairing processes. The apparatus comprises a positioning component and compressing component, wherein the middle part of the positioning component is hollow, and the positioning component is sleeved on a rotor iron core and fixed at the corresponding position of the rotor iron core; the compressing component is mounted between the positioning component and the rotor iron core; a magnetic steel is mounted between the compressing component and the rotor iron core; a drive assembly is arranged between the positioning component and the compressing component and controls the compressing component to radially move along the rotor iron core and relative to the positioning component so as to compress the magnetic steel, to be mounted, on the surface of the rotor iron core. Compared with the prior art, the apparatus, provided by the invention has the characteristics of simple and rational structure, capability in realizing of seamless assembling, and high effects of assembling and repairing processes; and the operation can be finished by one operator.

Description

technical field [0001] The invention relates to a surface-mounted permanent magnet synchronous motor, in particular to a surface-mounted permanent magnet synchronous motor magnet seamless assembly device and an assembly process using the assembly device, which effectively solves the problem of seamless assembly of small-sized magnets of the same polarity During the process, the problem of difficult assembly due to excessive repulsive force, at the same time, the invention also provides a repairing process after the magnetic steel is degummed. Background technique [0002] In recent years, with the rapid development of power electronics technology, microelectronics technology, new motor control theory and rare earth permanent magnet materials, permanent magnet synchronous motors have been rapidly popularized and applied. For example, the compressors widely used in refrigerators and air conditioners generally used squirrel-cage asynchronous motors before, and the speed was inc...
