Abstract
The utility model relates to a driving motor structure of an electromobile. The driving motor structure comprises a motor casing, a motor shaft, a rear end cover, a hall sensing steel magnet, a hall circuit board, a hall element, a radiating fan and a fan blade protection shade, wherein the rear end cover is fixedly arranged at one end of the motor casing; the hall sensing steel magnet is arranged on the motor shaft, and the hall circuit board is arranged on the rear end cover; the hall element is installed on the hall circuit board and faces right to the hall sensing steel magnet; and the radiating fan is arranged on the motor shaft, and the fan blade protection shade is fixedly arranged on the rear end cover for shielding the radiating fan. By arranging the hall element outside the motor, failure rate of the hall element is reduced, maintenance and installation are convenient, and the hall element is free of influence from the high temperature in the motor. The driving motor structure is installed under the radiating fan, has good radiating effect and accordingly improves stability in working of the motor.
