高速永磁电机
摘要：
本发明公开了一种高速永磁电机，包括电机转轴、固定套设于电机转轴上的转子、转动套设于转子外的定子和罩设于定子和转子外的机座，电机转轴转动连接于机座，转子与定子之间的间隔构成气隙轴向风道；机座内设有闭环风道且气隙轴向风道为闭环风道的一部分，电机转轴上固定有风扇，风扇设于闭环风道上以带动闭环风道上的空气循环流动。在电机转轴上直接固定风扇，电机转轴转动的同时风扇也会转动，另外，该风扇设置在闭环风道上，形成全封闭自循环通风冷却系统，该闭环风道途径转子，风扇带动闭环风道中空气循环流动以对转子进行风冷，能够有效对转子进行降温，提高了电机整体运行的可靠性。
摘要（英）：

The invention discloses a high-speed permanent magnet motor, comprising a motor shaft, a rotor which fixedly sleeves the motor shaft, a stator which rotationally sleeves the rotor, and a frame which covers the stator and the rotor. The motor shaft is rotationally connected to the frame. The gap between the rotor and the stator forms an air gap axial air duct. The frame is internally equipped witha closed-loop air duct, and the air gap axial air duct is a part of the closed-loop air duct. A fan is fixed on the motor shaft, and the fan is arranged on the closed-loop air duct to drive the air inthe closed-loop air duct to circulate. The fan is fixed directly on the motor shaft, and the fan will also rotate when the motor shaft rotates. In addition, the fan is arranged on the closed-loop airduct to form a totally closed self-circulation ventilating and cooling system, the closed-loop air duct passes through the rotor, and the fan drives the air in the closed-loop air duct to circulate to cool the rotor. The rotor can be cooled, and the overall operation reliability of the motor is improved.
