Preferably, described first back-up block shape is right-angled trapezium.
The right angle height sidewall of the first back-up block and teeth portion offset, and going to the bottom of this first back-up block is fixedly connected on opposite face, when the first back-up block right angle height sidewall is subject to the extruding force effect of teeth portion, this extruding force can be directly conducted to the joint face place between the first back-up block and opposite face, and the first back-up block adopts right-angled trapezium, this right angle sidewall and teeth portion can occur to fit comparatively closely, meanwhile effectively can increase the connection area of its large end and opposite face, increase the bonding strength between the first back-up block and opposite face, ensure stability in use.
Preferably, described first support group also comprises the second back-up block, and described second back-up block is connected to the first back-up block away from the sidewall of teeth portion.
First, the second back-up block can promote the support force of the first back-up block along iron core axial direction; Secondly, the second back-up block protrudes from opposite face, and when iron core rotates, the second back-up block plays effect that is similar and flabellum, stirs its ambient air, makes the air of flywheel inside that flowing velocity faster occur, promotes its radiating effect.
Preferably, described opposite face is provided with the second support group, and described second support group comprises and lays respectively at the first support group both sides the 3rd back-up block, and described radiating groove is between the 3rd back-up block and the first support group.
First, the 3rd back-up block can increase the structural strength of opposite face, promotes its anti-extrusion and anti-ability of colliding with in transportation; Secondly, the 3rd back-up block is similar with the second back-up block effect, can play the object of its ambient air of stirring equally, make the air of flywheel inside that flowing velocity faster occur, promote its radiating effect.
Preferably, described insulation framework is made by strengthening nylon.
For the drawback avoiding that its plastics purity of existing insulating support is low, easy conductive, insulation property are weak, anticollision performance is low, high temperature resistant etc., therefore insulation framework have employed enhancing nylon, this material has higher hot strength, bending strength, impact strength, and when reality uses, itself and extraneous hard object is collided with time very solid.
In sum, the beneficial effect that the utility model in contrast to prior art is: by arranging radiating groove, effectively can increase the air circulation air of flywheel inside, and then promote the air flow rate of its inside, promotes the heat dispersion of stator core.
