This invention discloses a high torque density dual-rotor motor and an electric wheelchair using this motor. The motor is a radial flux motor, comprising a stator assembly, an outer rotor, an inner rotor, a planetary gear assembly, a connecting disc, a front cover, and a rear cover. The front and rear covers are joined to form a cavity that encloses all core components. The stator assembly has two optional structures: one is where the stator teeth and windings are fixed to the support disc and the closed slots in the stator's inner diameter by filling with epoxy resin; the other is where several individual stator teeth with windings are connected and fixed into a single unit using epoxy resin, and the entire unit is fixed to the support disc. Finally, the support disc fixes the entire stator to the front cover. In this design, the connecting disc enables synchronous rotation of the inner and outer rotors and transmits power to the shaft. The planetary gear assembly is built into the cavity to amplify torque. Most components of this motor use interference fits, resulting in a compact and lightweight structure with high torque density and transmission efficiency, stable operation, and suitability for the hub motor requirements of electric wheelchairs.
