The invention relates to a self-adaptive stepless speed change built-in motor which comprises a shell, a power-assisted motor, a main motor, a generator and a center shaft, a rotor of the power-assisted motor is connected with an output shaft of the power-assisted motor through a power-assisted motor one-way clutch, and a rotor of the main motor is coaxially connected with the output shaft of the power-assisted motor through a main motor one-way clutch. An output shaft of the power-assisted motor is supported on the shell through a bearing, and an output end gear of the output shaft of the power-assisted motor is meshed with an output speed reducing mechanism. A rotor of a generator is connected to the middle shaft, the rotor of the generator is coaxially connected with the planetary speed increasing mechanism, and the generator, the power-assisted motor and the main motor form a stepless speed change motor combined structure. The self-adaptive stepless speed change middle motor has the beneficial effects that the self-adaptive stepless speed change middle motor is designed by utilizing the characteristic that the output load of the motor is inversely proportional to the input current, so that the output speed is automatically adjusted, the riding comfort is improved, a torque sensor is omitted, and the overall structure of the bicycle is simplified.

    本发明涉及一种自适应无级变速中置电机,包括壳体、助力电机、主电机、发电机和中轴,助力电机的转子通过助力电机单向离合器与助力电机输出轴连接,主电机的转子通过主电机单向离合器与助力电机输出轴同轴连接,助力电机输出轴通过轴承支撑在壳体上,助力电机输出轴输出端齿轮啮合有输出减速机构;中轴上连接有发电机的转子,发电机的转子与行星增速机构同轴连接,发电机与助力电机和主电机构成无级变速电机组合结构。有益效果:由发电机、助力电机和主电机构成的无级变速电机组合,利用电机输出负荷与输入电流成反比的特性,设计的自适应无级变速中置电机,实现自动调节输出速度,提高骑行舒适度,省去力矩传感器,而且简化自行车整体结构。
