The end face center of described front end housing is provided with axis hole, and the end face center of described rear end cap is provided with axis hole; Described front end housing and the end face of rear end cap are respectively provided with corresponding ventilation hole and screw, and described ventilation hole has one at least, and described screw has two at least.
The rotating speed of described motor can reach 40000r/min, the more air output of energy fan, thus reaches larger pick-up performance.
Described hall sensing plate comprises substrate and semiconductor inductive component.
A kind of packaging technology of motor of dust collector: first, stator core is loaded onto coil rack according to the setup parameter of motor, then stator winding is had mercy on be connected on stator core and detect resistance value between each winding, setup parameter that whether class of insulation meets motor, complete the assembling of stator module afterwards; Secondly, rotor punching is pressed into armature spindle, again permanent-magnet steel is fixed on rotor punching by tenacity viscose, then first magnetic steel sleeve be pressed into from the two ends of armature spindle and be fixed by socket the two ends at permanent-magnet steel, again bearing is pressed into from the front and back ends of armature spindle respectively, completes the assembling of rotor assembly afterwards; Then, first stator module is assemblied in rear end cap, again the rear end bearing of rotor assembly is assemblied in the axis hole of rear end cap, refill and join front end housing and make the front end bearing of rotor assembly be arranged in the axis hole of front end housing, finally, through the screw of front end housing and rear end cap, front end housing and rear end cap are screwed tight fixing with screw.
Beneficial effect: the present invention is good heat dissipation effect not only, and no-spark in the course of work, without ablation, can more badly, work in more dangerous environment, and little, the low noise of rubbing, the life-span is long, energy consumption is low, the general direct current machine of Performance Ratio is more superior.
