Fig. 1 to 5 are schematic views illustrating a magnetic steel fixing structure in a rotor of a disc motor according to a preferred embodiment of the present invention, including a rotor disc 100, a plurality of magnetic steels 200, a hoop 300, and at least two clamping members 400, where the rotor disc 100 includes a base 110 and a plurality of supports 120, the supports 120 extend outward from a periphery of the base 110, and an insertion groove 121 is formed at one end of at least two of the supports 120 facing away from the base 110; the number of the plurality of magnetic steels 200 is the same as that of the plurality of supporting parts 120, and the plurality of magnetic steels 200 are respectively fixed to extend outwards to the base part 110 and are arranged at intervals with the supporting parts 120; the hoop 300 is fixed to the outer periphery of the magnetic steel 200, so that the magnetic steel 200 is fixed between the hoop 300 and the base 110; the number of the clamping members 400 is the same as that of the caulking grooves 121, and the clamping members 400 are mounted on the side surfaces of the hoop 300, which are matched with the outer periphery of the magnetic steel 200, so that when the hoop 300 is sleeved on the outer periphery of the magnetic steel 200, the clamping members 400 are clamped in the caulking grooves 121.
Place between two adjacent supporting parts 120 magnet steel 200, so that it is a plurality of magnet steel 200 is the annular arrangement, then will hoop 300 cover is located the outer peripheral edges of magnet steel 200, and make joint spare 400 with caulking groove 121 block on the supporting part 121, in order to realize magnet steel 200 is fixed in hoop 300 with between the basal portion 110, for prior art, effectively prevent hoop 300 takes place axial displacement or rotatory in-process and takes place the pine and take off the risk to need not injecting glue between magnet steel and rotor disc, and need not to destroy the magnet steel structure and in order to adapt to the screw fixed mode, avoided connecting failure, and equipment convenient and fast.
As shown in fig. 3 and 5, the short axial dimension of the rotor disc 100 means that the thickness of the rotor disc 100 is thinner, the thickness of the base portion 110 and the supporting portion 120 can be consistent, wherein the support 120 comprises two opposite first and second sides 1201, 1202 on either axial side of the rotor disc 100, the distance between the first side 1201 and the second side 1202 refers to the thickness of the support 120, the insertion groove 121 is located on the end of the support 120 facing away from the base 110, extending from a middle position of the end to the first side 1201, i.e. the length of the extension of the insert groove 121 is smaller than the distance between the first side 1201 and the second side 1202, so that the clip 400 can slide into the insertion groove 121 from the first side 1201, and is engaged with the insertion groove 121 to make the hoop 300 be sleeved on the outer periphery of the magnetic steel 200.
Since the extension length of the insertion groove 121 is smaller than the distance between the first side 1201 and the second side 1202, therefore, when the clip 400 is engaged with the slot 121, the two sides of the hoop 300 are flush with the two sides of the magnetic steel 200, the outer periphery of the hoop 300 can be contacted and fixed, the thicknesses of the hoop 300 and the magnetic steel 200 are consistent, the radial displacement of the magnetic steel 200 in the high-speed rotation process is effectively prevented, it can be seen that the extension length of the slot 121 determines the matching relationship between the hoop 300 and the magnetic steel 200, of course, the thickness of the hoop 300 may be smaller than that of the magnetic steel 200, and when the clip 400 is engaged with the slot 121, the collar 300 is positioned between the first side 1201 and the second side 1202, that is, the hoop 300 may be located at the middle position of the magnetic steel 200 to improve the fixing effect of the hoop 300 on the magnetic steel 200.
