A shaft-driven double-stator multi-speed motor with equal-width curves comprises a rotor (5), an inner stator (19), an outer stator (3), a slide block group (22), a left end cover (6) and a right end cover (1). The exterior surface curve of the front part of the inner stator (19) and the inner surface curve of the outer stator (3) are two identical smooth enclosed curves. The slide block group (22) is arranged on the rotor (5). Several outer stator oil distributing windows (20) are provided on the outer stator (3). The number of the outer stator oil distributing windows (20) is 2*n, in which n is an action number. Several inner stator oil distributing windows (24) are provided on the exterior surface of the front part of the inner stator (19). The inner stator (19) is arranged in the rotor (5). The multi-speed motor has the advantages of stable work, small volume, light weight, high efficiency and high specific power. A plurality of hydraulic motors with a plurality of different inputs is arranged in a shell. When the motors have different inputs or outputs, various different rotational speeds and torques could be output. |
