Fig. 1 is the vertical view of one preferred embodiment of double brake Cone-shaped electric machine provided by the invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that the described embodiments are merely a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is the vertical view of one preferred embodiment of double brake Cone-shaped electric machine provided by the invention.
The double brake Cone-shaped electric machine includes Cone-shaped electric machine 1, electromagnetic brake 2 and cone brake 3.The electromagnetic braking Device 2 is connect with the Cone-shaped electric machine 1, and the electromagnetic brake 2 is set between the Cone-shaped electric machine 1 and the cone brake 3.
The Cone-shaped electric machine 1 includes motor shaft, rotor 13, stator 12, engine base 14, motor front end cover 15, motor spring 16 And rear end cap 17.The motor shaft is set on the Cone-shaped electric machine 1, the Cone-shaped electric machine 1, the electromagnetic brake 2 and described Cone brake 3 is set on the motor shaft.The rotor 13 is conical by its shape, and is set to 12 relative inner of the stator, 12 inside of the stator is conical socket shape, is correspondingly arranged with 13 structure of the rotor, the motor shaft is set to the rotor 13 opposite cental axial positions.The stator 12 is set to 14 inside of the engine base, and the motor shaft passes through the rotor 13, and passes through The motor front end cover 15 and the rear end cap 17, the stator 12 and the rotor 13 be set to the motor front end cover 15 with Between the rear end cap 17, the motor spring 16 encloses on the motor shaft, and is set to the motor front end cover 15 and institute It states between stator 12.
