E-shaped stator core flux switching type hybrid permanent magnet memory motor
A hybrid permanent magnet and memory motor technology, which is applied to the static parts of the magnetic circuit, the shape/style/structure of the magnetic circuit, etc., can solve the difficulty of implementing the excitation current control system, reduce the power density and force performance of the motor, and reduce the speed of the motor. Problems such as moment density and torque ripple are large, so as to achieve the effect of easy heat dissipation, reducing end effect, and realizing online magnetic adjustment

Embodiment Construction
[0041] The present invention will be further explained below in conjunction with the drawings.
[0042] An E-shaped stator core magnetic flux switching type hybrid permanent magnet memory motor, such as figure 1 As shown, it includes a stator (1), a three-phase armature concentrated winding (5) and a pulse magnetization winding (6) adapted to the stator, a salient pole rotor (2), and a non-magnetic rotating shaft (9); The stator (1) is arranged outside the rotor (2), and the rotor (2) is fixed on the non-magnetic rotating shaft (9) and is of salient pole type;
[0043] The stator (1) has a layered structure; the stator (1) includes more than one "E"-shaped stator core (1.1) and an outer stator yoke (1.2), the "E"-shaped stator core (1.1) Evenly distributed along the circumferential direction of the salient pole rotor (2), and the outer stator yoke (1.2) is arranged on the outside of the "E"-shaped stator core (1.1); the outer stator yoke (1.2) and the "E" The "V"-shaped Al-Ni-Co ...
