HYBRID DUAL-ROTOR STRUCTURE

摘要

A hybrid dual-rotor motor structure is provided, which may include a stator, a first rotor, a second rotor, a first coil, and a second coil. The stator may include a plurality of stator teeth. The first rotor, the second rotor, and the stator may arranged in the radial direction of the hybrid dual-rotor motor structure. The first coil may be wound on the stator teeth. The second coil may be wound on the stator teeth; the second coil may include a plurality of sub-coil sets; each of the sub-coil sets may include a plurality of sub-coils connected to each other/one another in series or in parallel; the pole-pair number of the second coil may be the integral multiple of the pole-pair number of the first coil.
