1. a multitooth magnetic bridge type hybrid excitation magnetic flux switching motor is characterized in that this motor comprises:

  • the rotor (5) of stator (1), permanent magnet (2), armature winding (3), single-phase excitation winding (4) and salient pole type;

    Both do not had permanent magnet on the rotor (5) and do not had winding yet;

    Stator (1) comprising;

    be distributed in the stator poles (7) of a plurality of U types on the circumference and the iron core that constitutes one with each stator poles (7) and be connected in each stator poles (7) periphery is connected magnetic bridge (6);

    Each stator poles (7) has two ends, and each end is provided with two stator tooths (8), and the same circle distribution of stator tooth (8) on each stator poles (7);

    Described permanent magnet (2) is located between the adjacent U type arm of adjacent two stator poles (7), and described armature winding (3) is located on the adjacent U type arm of adjacent two stator poles (7);

    The curved bottom of the stator poles of described each U type (7) is connected magnetic bridge (6) through connecting portion with iron core and is connected as a body, and each connecting portion is provided with magnet exciting coil, and the head and the tail series connection in regular turn of each magnet exciting coil constitutes single-phase excitation winding (4).
