The invention discloses a miniature electric drive wheel which comprises a stator assembly, a rotor assembly, an outer tire shell, a circuit board, an elastic check ring and induction magnetic steel, the rotor assembly comprises a hollow shaft, a motor shell and a motor magnetic ring, the hollow shaft is coaxially and rotatably connected relative to a fixed base through a bearing, the hollow shaft is provided with an assembly space, and the induction magnetic steel is arranged in the assembly space. The motor shell is connected with the hollow shaft, the motor magnetic ring is connected with the motor shell, a riveting point is arranged at the outer end of the hollow shaft, a limiting ring groove is formed in the inner end of the hollow shaft, the outer end of the hollow shaft is riveted with the outer tire shell through the riveting point, the inner side portion of the elastic check ring is clamped into the limiting ring groove, and the outer side portion of the elastic check ring abuts against the rotating portion of the bearing. And a magnetic field sensor is arranged on the circuit board and is used for acquiring a position signal of the induction magnetic steel and adjusting the relative position of the stator assembly and the rotor assembly according to the position signal. According to the miniature electric drive wheel, the running stability performance and the safety performance of the miniature electric drive wheel are improved.
