Abstract

The invention relates to the technical field of electric transmission systems and discloses a permanent magnet electric roller with a non-return device. The electric roller comprises a rotor assembly,a first end cover assembly, a second end cover assembly, a backstop, a stator assembly, a fixed seat and a junction box assembly. The second end cover assembly is fixedly connected with the backstopthrough a flange ring and the second end cover assembly and the backstop are both located in one end of the rotor assembly cylinder. The stator assembly is located in the rotor assembly, and the two ends of the stator assembly are fixed to the first end cover assembly and the second end cover assembly respectively. According to the permanent magnet electric roller, the backstop is arranged in therotor assembly, the overall length of the permanent magnet electric roller is shortened, meanwhile, the inclined air inlet is adopted, the air guide effect in the permanent magnet electric roller is improved, and the heat dissipation effect of the permanent magnet electric roller is further improved.

Description

technical field [0001] The invention relates to the technical field of electric transmission systems, in particular to a permanent magnet electric drum with a backstop device. Background technique [0002] The outer rotor permanent magnet drum has the advantages of simple structure, reliable operation, less loss, high efficiency, and can realize direct drive control, etc. It is especially suitable for low-speed, high-torque applications, so it is widely used in petroleum, mining, metallurgy, steel rolling and other industries. This typical equipment transmission system has been widely used, especially in high-power transmission systems. [0003] In the Chinese patent CN110224508A, a stator frame and a drum motor are disclosed. An air inlet 64 communicating with the air guide hole is provided on the outer surface of a section where the connecting shaft is located in the heat exchange chamber. The air inlet 64 is vertically distributed on the On the connecting shaft, the side...
