Compared with prior art, the present invention has following advantage and disadvantage:
(1) the present invention adopts the front cover that the wheel hub of fan blade instead of motor, the mounting nuts that to instead of rear end cover with the baffle plate of fan housing, instead of fan blade nut, instead of motor with the own material of motor case with the own material of armature insulating bush, thus has the advantage that part is few, material is economized, manufacturing procedure is few;
(2) wheel hub of fan blade be directly connected with armature and together with rotate, the stator of motor directly and the baffle plate of fan housing be fixedly linked, eliminate front cover and rear end cover, thus shorten the axial distance of motor;
(3) wheel hub of fan blade is directly fixed together with armature insulation cover, can reduce the jerk value of fan, thus makes assembly vibrate reduction; The stiffening rib of wind impeller boss rotates with radiating fin can directly dispel the heat to motor internal with armature.
(4) eliminate three gussets, not only material saving, and add air-out area, further increase heat radiation and cooling effect.
