Claim 34:
35. A motor comprising:
a stator assembly, comprising a stator core and two groups of mutually independent windings, wherein a hollow channel is arranged in a radial middle part of the stator core, wherein two axial end portions of the stator core are provided with stator teeth protruding towards two axial sides of the stator core, and wherein the two groups of windings are wound on two groups of stator teeth respectively;
two mutually independent rotor assemblies, being oppositely and coaxially arranged on two axial sides of the stator assembly and forming an axial air gap with the stator assembly, wherein the two rotor assemblies are configured to rotate independently;
two mutually independent rotating shaft assemblies being coaxially connected with the two rotor assemblies respectively and protruding in a direction of the same side away from the stator core along an axial direction of the motor, wherein parts of the two rotating shaft assemblies are arranged in the hollow channel;
an insulating frame, being mounted on at least one stator tooth;
a mounting bracket, being fixedly connected to the insulating frame; and
a plurality of contact pins, being inserted to the mounting bracket,
wherein lead-out wires of the two groups of windings are fixedly connected to the plurality of contact pins,
wherein the mounting bracket is of an arc-shaped strip structure coaxial with the stator assembly, and
wherein the mounting bracket and the plurality of contact pins are positioned on the radial outer side of the rotor assemblies.
