The invention discloses a magnetic levitation induction motor electric bicycle driving system, which comprises a shell, a motor rotor, a motor stator, a motor shaft, an end cover, an auxiliary bearing, magnetic steels, outer windings and a detection control system, wherein the motor rotor and the shell are closely connected; the magnetic steels are arranged on the left-side end surface and the right-side end surface of the motor rotor; the inner side of the shell is provided with the outer windings; an axial position sensor is arranged on the shell at the inner side of the outer winding along the circumferential direction; the motor stator is fixed on the motor shaft; and a radial position sensor and a rotation speed sensor are arranged at the outer side of the motor stator along the circumferential direction. Through the magnetic levitation technology, no contact and no friction between the rotor and the stator can be realized, the vehicle body is supported in a no wear mode, the wheel is driven to rotate directly through electromagnetic torque, the transmission chain is shortened, the driving efficiency is improved, energy consumption is reduced significantly, the power performance of an electric bicycle is improved, and the response speed is fast.
