The utility model is achieved through the following technical solutions:
The utility model provides a kind of brshless DC motor, this brshless DC motor comprises: shell, be arranged on front end housing and the rear end cap at described shell two ends, be fixed on the stator module in described housing, also comprise: the rotating shaft be rotationally connected with described front end housing and described rear end cap, wherein, described rotating shaft is exposed through after described front end housing, described rotating shaft is fixedly installed the rotor assembly coordinated with described stator module, and described rotor is set with the radiator fan of drying towards described stator module.
Preferably, be rotationally connected by bearing between described front end housing and described rotating shaft.
Preferably, be rotationally connected by bearing between described rear end cap and described rotating shaft.
Preferably, described front end housing and described rear end cap are respectively arranged with louvre.
Preferably, described front end housing is triangle, and each angle of described triangular front end lid is provided with and the circular port that convex support structure matches of three on centrifugal blower volute.
The beneficial effects of the utility model are: brshless DC motor adopts special-purpose assorted centrifugal blower volute to design, motor radiating mode adopts built-in radiator fan, can directly cooled machine heating part, good heat dissipation effect, more high power density can be designed, thus reduce the volume and weight of motor.It is little that brshless DC motor has volume, lightweight, and efficiency is high, and caloric value is little, and noise is low, and the life-span is long, can realize the plurality of advantages such as stepless time adjustment, is applicable to very much being assemblied on centrifugal high pressure fan.This motor adopts the mode controlled without Hall element, saves Hall element, thus saves cost, and structure is simply and more reliable.
