Abstract

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.

Dependent claims

A hybrid dual-rotor motor structure, comprising:

a stator, comprising a plurality of stator teeth;
a first rotor;
a second rotor, wherein the stator, the first rotor, and the second rotor are arranged in the radial direction of the hybrid dual-rotor motor structure;
a first coil, wound on the stator teeth and connected to the first rotor;
and
a second coil, wound on the stator teeth and connected to the second rotor, wherein the second coil comprises a plurality of sub-coil sets;
each of the sub-coil sets comprises a plurality of sub-coils connected to each other/one another in series or in parallel;
a sum of the pole-pair number of the first coil and a pole-pair number of a magnet set of the first rotor is equal to a quantity of the stator teeth, and the pole-pair number of the second coil is equal to a pole-pair number of a magnet set of the second rotor, whereby a magnetic flux linkage between the first coil and the second coil is able to be further reduced so as to independently control the first rotor and the second rotor.
