Embodiment Construction
[0013] As shown in the drawings, the motor body 1 is a permanent magnet brushless DC motor, and the rotor magnet 4 of the motor body 1 is made of rare earth NdFeB permanent magnet material to generate the rotor magnetic field; the end of the stator winding 5 is equipped with three rotor magnets. The steel position sensor 6 is used to detect the position of the rotor magnet 4, the rotor magnet position sensor 6 is connected with the motor controller 2, and the commutation is realized through the motor controller 2. The motor body 1 and the motor controller 2 have an explosion-proof casing 3: the explosion-proof casing 3 includes the motor front cover 7, the motor casing 8, the motor rear cover 9, the control box 10, the control box cover 11, the rotor explosion-proof sleeve 12, and the switch operation part 13 And cable entry device 14. Motor front cover 7, motor casing 8, motor back cover 9, control box 10, control box cover 11 are connected into a whole by fastening screw 15,...
