Sealed high-voltage direct-current brushless outer rotor fan

The invention discloses a sealed high-voltage direct-current brushless outer rotor fan. The fan is mainly composed of a fan outer support, fan blades, a controller shell, a stator shell, a rotor shell, a sealing rubber mat, a front end sealing cover, an oil seal, an oil seal sealing ring, a rotor bearing, a stator electromagnet and the like. Through cooperation of a built-in structural layout modeof an outer rotor and a unique axial double-seal oil seal structure, a core sealing problem of the fan motor is solved while a large-torque operation characteristic of an outer rotor motor is ensured; besides, by designing a unique stator fixing seat and front and rear end cover sealing structures, the weight of the product is reduced, the product is light in weight, the interior of the motor iscontinuously and well cooled, and the overall service life of the product is prolonged. 本发明公开了一种密封型高电压直流无刷外转子风扇，风扇主要由风扇外支架、风扇扇叶、控制器外壳、定子外壳、转子外壳、密封胶垫、前端封盖、油封、油封密封圈、转子轴承、定子电磁铁等部分构成。通过外转子内置的结构布局方式配合独特的轴向双密封油封结构，在保证外转子电机大扭矩运转特点的同时
