The invention relates to a stepless speed change built-in motor which comprises a shell, a power assisting motor, a generator and a middle shaft, a left half shaft is connected with a torque sensor, the torque sensor is connected with a first planet carrier, a gear ring supporting frame is supported on the first planet carrier, a first gear ring and a third gear ring are fixedly connected to the gear ring supporting frame, the first gear ring is meshed with a first planet wheel, and the third gear ring is meshed with a second planet wheel. The first planet gear is meshed with the first sun gear to form a first speed change structure; a third gear ring is meshed with a right gear of a duplex planet gear, a left gear of the duplex planet gear is meshed with a second gear ring fixed on the shell, the left gear is meshed with a third sun gear, and the third sun gear is fixedly connected with a generator rotor to form a second speed change structure; and an input gear of the first planet carrier is meshed with the transition gear and is meshed with an output shaft gear of the power-assisted motor. The electric bicycle has the advantages that manual power and power of the power-assisted motor are converged on the first planet carrier of the planet wheel speed change mechanism and output after speed change, and a rider can ride the bicycle with the most comfortable force and the most comfortable pedaling frequency.

    本发明涉及一种无级变速中置电机,包括壳体、助力电机、发电机、中轴,左半轴与力矩传感器连接,力矩传感器与第一行星架连接,第一行星架上支撑有齿圈支撑架,齿圈支撑架上固接有第一齿圈及第三齿圈,第一齿圈与第一行星轮啮合,第一行星轮与第一太阳轮啮合,构成第一变速结构;第三齿圈与双联行星轮右侧齿轮啮合,双联行星轮左侧齿轮与固定在壳体上的第二齿圈啮合,左侧齿轮与第三太阳轮啮合,第三太阳轮与发电机转子固接,构成第二变速结构;第一行星架的输入齿轮与过渡齿轮啮合,并与助力电机的输出轴齿轮啮合。有益效果:将人工动力与助力电机动力交汇于行星轮变速机构的第一行星架通过变速后输出,骑行者能够以最舒适的力度及踏频骑行。
