[0028] See figure 1 , figure 2 , The magnetically increased salient pole type hybrid excitation synchronous motor of the present invention includes a shaft 1, a bearing 2, a front end cover 3, a stator winding 4, a casing 5, a stator core 6, a rotor core 7, a permanent magnet steel 15, and a rotor pressure plate 8. , Electric excitation winding 9, rear cover 10, junction box assembly 11, resolver 12, brush 13 and brush junction box 14.
[0029] The stator core 6 and the stator winding 4 in the present invention adopt the conventional permanent magnet synchronous motor stator structure; the rotor core 7 is similar in appearance to the rotor of the salient-pole electric excitation synchronous motor, with electric excitation windings and the quadrature axis air gap larger than the direct axis air gap .
[0030] Each rotor magnetic pole of the rotor core 7 in the present invention is designed with two "V"-shaped magnetic steel grooves, and the magnetic steel 15 of the same polarity ...
