Abstract
The utility model discloses a multi-magnetic-pole rotor which comprises a cylindrical magnet (1). A center of the magnet (1) is provided with a through hole. The rotor is characterized in that: a plastic fixing piece (2), which fixes the magnet (1), is injection molded in the through hole. The center of the through hole is also provided with a rotating shaft (3) which is injection molded together with the fixing piece (2) and closely integrated with the fixing piece (2). Six magnetic poles are arranged on the magnet (1). Keyways (32) and annular grooves (33) are arranged at a contact part of the rotating shaft (3) and the fixing piece (2). The rotating shaft (3) is made of a metal material and one end of the shaft (3) is also provided with splines (31). Two ends of the fixing piece (2) are provided with separation blades (21) which clamp the magnet (1) in between. A separation blade (21), which is at an output end of the rotating shaft (3), is also provided with an annular rib (22).
Description
[technical field]
The utility model relates to rotor, especially a kind of rotor of many magnetic poles.
[background technology]
It is not very tight coordinating between existing rotor magnet and rotating shaft, so in use rotating shaft easily with magnet disengaging, reduction of service life.
[utility model content]
, in order to solve deficiency of the prior art, provide a kind of rotor of rotating shaft fixation.
The technical scheme that the utility model adopts is:
A kind of many pole wheels, include a cylinder-shaped magnet, be provided with through hole at described magnetic blow out centre, be injected with the plastic fixtures of fixed magnet in described through hole, also be provided with at described through hole center one with together injection moulding and the rotating shaft that is closely linked of fixture.
Be provided with six magnetic poles on described magnet.
Be provided with keyway and annular groove in affiliated rotating shaft and fixture contact portion.
Described rotating shaft material is metal material, and at described rotating shaft one end, also is provided with spline.
Described fixture two ends are provided with the catch that magnet is clipped in the middle, and at the catch of output one side of described rotating shaft, also are provided with annular ridge.
Adopt the rotor of top structure, because rotating shaft and fixture are together injection molded, and be provided with keyway in rotating shaft, during injection moulding, fixture can be injected in keyway and guarantee to be connected firmly between rotating shaft and fixture, make the synchronism of rotating shaft better, longer service life.
