    摘要： The present invention discloses a new type of mixed-wave permanent magnet motor, which relates to the field of motor technology. It comprises a motor shell, a stator and a rotor, wherein, the stator and the rotor are arranged in the motor shell; the stator comprises a fixed ring and stator iron cores, a plurality of the stator iron cores are distributed on a cover plate in circular mode, and the stator iron cores are wound with magnetic induction lines passing through the coils at both radial sides of stator iron cores; the rotor comprises an outer rotor part and an inner rotor part, and the outer rotor part is arranged outside the cylindrical inner rotor part; a stator zone is formed between the outer rotor part and the inner rotor part; the stator is located within the stator zone of the rotor. By designing the structure of the stator and rotor, the invention utilizes the magnetic field on both sides of the stator to drive the rotor, which avoids the waste of energy. Compared with the traditional motor, the present invention uses fewer winding sets to realize the same power, which reduces the stator volume, saves the winding material, and realizes high economic benefit.

    摘要： A method for assembling the teeth (d) that constitute the stator poles of a stator (S) for electric motors, comprising at least the steps of:
    a. positioning the teeth (d) between a radial expansion device (30) and a plurality of radial compression devices (40);
    b. expanding in a coordinated manner the radial expansion device (30) and the radial compression devices (40) until all the teeth (d) are arranged at the same radial distance from a central axis (Y); the expansion of the radial expansion device (30) and the expansion of the radial compression devices (40) being coordinated by an electronic control unit as a function at least of the distance of each tooth (d) from the central axis (Y) and of the pressure applied by each one of the radial compression devices (40) to each tooth (d);
    c. mutually fixing the teeth (d) in the position reached in point b so as to form a single stator element (S);
    d. extracting the stator element (S).
    The invention also relates to an apparatus for performing the method.
