Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 6, a kind of brushless electric motor rotor assembly for treadmill, including line shaft 1 and power is arranged at
The bearing 2 at the two ends of axle 1, also including insulating support 3 and multiple silicon steel sheets 4, the silicon steel sheet 4 refers to the gold made using material silicon
Category steel disc, the insulating support 3 is provided with the centre bit 31 for housing silicon steel sheet 4, and the silicon steel sheet 4 is arranged at centre bit 31
And screens 5 is formed with insulating support 3, the screens 5 is equiped with magnetic part 6, and the silicon steel sheet 4 is provided with and is passed through for line shaft 1
Centre bore 41；This rotor assembly forms screens 5 by silicon steel sheet 4 and insulating support 3, so that magnetic part 6 is located at screens 5
In, inner support is formed by silicon steel sheet 4 in inner side, centrifugation limitation is formed by insulating support 3 in outside, it is ensured that the connection of magnetic part 6
Stability, this rotor structure has the advantage of assembling mode, compact conformation and good stability.
In the technical program, the insulating support 3 include foundation ring and along foundation ring circumference uniform distribution multiple " T " shape skeleton
32, each two " T " shape skeletons 32 form screens 5 with silicon steel sheet 4.One torus is substantially carried out decile and is formed by magnetic part 6, is matched somebody with somebody
During conjunction, magnetic part 6 is located at respectively " T " shape skeleton 32 both sides, using " T " shape skeleton 32 formed limitation, simultaneously as " T " shape
Skeleton 32 will be generally plastic material, so, can by magnetic part 6 with " T " shape skeleton 32 carries out close-fitting, without bonding.
In the technical program, the silicon steel sheet 4 includes disk body and the multiple protuberances 42 along disk body circumference uniform distribution, described
