[0006] In a preferred embodiment of the flexible compliant torque magnetic electric drive provided by this utility model, the cylindrical fixing component includes a cylindrical fixing component body and two magnetic pole rotor fixing flanges.

The flexible torque-converting magnetic drive motor includes a stator assembly 11 and a rotor assembly rotatable relative to the stator assembly 11. The rotor assembly includes a main shaft 121, two outer end flanges 122, a cylindrical fixing member 123, a magnetic pole rotor 124, and a high-strength steel wire rope 125. The two outer end flanges 122 are spaced apart on the main shaft 121 and fixedly connected to it. The cylindrical fixing member 123 is sleeved on the main shaft 121 between the two outer end flanges 122 and rotatably connected to the main shaft 121. The magnetic pole rotor 124 is fixedly disposed on the outer peripheral wall of the cylindrical fixing member 123 and spaced apart from the inner peripheral wall of the stator assembly 11. The opposite end faces of the two outer end flanges 122 are... A plurality of first fixing members 126 are evenly arranged along the circumference of the outer end flange 122. A plurality of second fixing members 127 corresponding to the first fixing members 126 are evenly arranged along the circumference of the cylindrical fixing member 123 at both ends.
