Zusammenfassung: | The invention provides an electrically-excited bidirectional rotating electromagnet with horizontal moment-rotation angle characteristics. A rotor and an output shaft are installed in a stator. The boxy stator is formed by splicing half-boxy left stator yoke iron and right stator yoke iron, and a stator pole extends out of the corner of each piece of stator yoke iron along an angular bisector; andthe four stator poles are distributed on the boxy diagonal at the interval of 90 degrees. Control coils are arranged in the middle of the right and left stator yoke iron to form control magnetic flux; the upper and lower sides of the right and left stator yoke iron are provided with excitation coils to form a bias magnetic field. The rotor is in an X shape, and four large teeth are distributed atthe position, corresponding to stator teeth, of the circumference of the rotor; and the end face of each large tooth comprises a circular-arc tooth surface and a rectangular surface, and the tooth surface and the radial end s |
