High power density permanent magnet brushless double-feed electric motor in novel structure

The invention provides a high power density permanent magnet brushless double-feed electric motor in a novel structure. The motor comprises a first stator, a second stator and a rotor; the first stator and the second stator are arranged on two sides of the rotor; an external air gap is formed between the first stator and the rotor; an internal air gap is formed between the rotor and the second stator; the first stator and the second stator are connected through a stator support to be fixed; permanent magnets are arranged on the internal side and the external side of the rotor; the rotor is fixed on a rotary shaft; the first stator and the second stator are respectively provided with an armature winding. The high power density permanent magnet brushless double-feed electric motor in the novel structure can reduce manufacturing costs and improve the motor power density and efficiency.
