Description
技术领域Technical Field
本发明涉及磁通切换电机领域，具体的是一种定子分裂式定子永磁型轴径向混合磁场永磁磁通切换电机。The invention relates to the field of flux switching motors, in particular to a stator split type permanent magnet type axial radial mixed magnetic field permanent magnet flux switching motor.
背景技术Background Art
传统定子永磁型永磁磁通切换电机通常采用双凸极结构，电枢绕组与永磁体均位于定子上，转子上既无绕组也无永磁体，结构简单，使得电机具有高功率密度，高转矩密度，高效率等优点。但是定子永磁型轴向磁场磁通切换电机，永磁体位于定子使得电枢绕组槽面积被严重挤压，定子齿部磁路饱和严重，使得电机气隙磁密谐波含量增加，气隙磁密正弦度差；并且使得电机绕组铜耗与定子损耗急剧增加，削弱电机过载状态下转矩能力，电机整体发热严重，对电机工作寿命与可靠性产生不良影响。Traditional stator permanent magnet type permanent magnet flux switching motors usually adopt a double salient pole structure, where the armature winding and permanent magnets are both located on the stator, and there are neither windings nor permanent magnets on the rotor. The structure is simple, making the motor have the advantages of high power density, high torque density, high efficiency, etc. However, in the stator permanent magnet type axial magnetic field flux switching motor, the permanent magnet is located in the stator, which causes the armature winding slot area to be severely squeezed, and the stator tooth magnetic circuit is severely saturated, which increases the harmonic content of the motor air gap magnetic density and the air gap magnetic density sinusoidal degree; and causes the motor winding copper loss and stator loss to increase sharply, weakening the torque capacity of the motor under overload conditions, causing serious overall heating of the motor, and having an adverse effect on the motor's service life and reliability.

上述电机的工作运行原理：由于轴向磁场第一电枢定子1、轴向磁场第一转子2、励磁定子3，径向磁场转子4与径向磁场电枢定子5所形成的磁路与轴向磁场第二电枢定子7、轴向磁场第二转子6、励磁定子3，径向磁场转子4与径向磁场电枢定子5的磁路对称，所以结合图7与图8，以轴向磁场第一电枢定子1、轴向磁场第一转子2、励磁定子3，径向磁场转子4与径向磁场电枢定子5 中所组成的磁路对电机工作原理进行描述。The working principle of the above-mentioned motor is as follows: since the magnetic circuit formed by the axial magnetic field first armature stator 1, the axial magnetic field first rotor 2, the excitation stator 3, the radial magnetic field rotor 4 and the radial magnetic field armature stator 5 is symmetrical with the magnetic circuit of the axial magnetic field second armature stator 7, the axial magnetic field second rotor 6, the excitation stator 3, the radial magnetic field rotor 4 and the radial magnetic field armature stator 5, the working principle of the motor is described in combination with Figures 7 and 8 using the magnetic circuit formed by the axial magnetic field first armature stator 1, the axial magnetic field first rotor 2, the excitation stator 3, the radial magnetic field rotor 4 and the radial magnetic field armature stator 5.
当轴向磁场第一转子2、径向磁场转子5运行至α1角度时，转子角度为α1时永磁磁通路径8在图7中进行表示，以A相为例，根据“磁阻最小原理”，永磁磁通沿箭头方向穿过A1、A2、A3、A4绕组；当轴向磁场第一转子2、径向磁场转子5与轴向磁场第二转子6运行至α2角度时，转子角度为α2时永磁磁通路径9在图8中表示，磁通沿箭头的方向穿过A1、A2、A3、A4绕组。在上述两种位置A1、A2、A3、A4绕组匝链的永磁磁通数值相同极性相反，当轴向磁场第一转子2与径向磁场转子5持续转动，A1、A2、A3、A4绕组匝链的永磁磁通在正负幅值之间发生周期性变化，对应产生幅值与相位交替变化的感应电动势。When the axial magnetic field first rotor 2 and the radial magnetic field rotor 5 run to an angle of α 1 , the permanent magnetic flux path 8 when the rotor angle is α 1 is shown in FIG. 7. Taking phase A as an example, according to the "minimum magnetic resistance principle", the permanent magnetic flux passes through the A1, A2, A3, and A4 windings in the direction of the arrow; when the axial magnetic field first rotor 2, the radial magnetic field rotor 5 and the axial magnetic field second rotor 6 run to an angle of α 2 , the permanent magnetic flux path 9 when the rotor angle is α 2 is shown in FIG. 8, and the magnetic flux passes through the A1, A2, A3, and A4 windings in the direction of the arrow. In the above two positions, the permanent magnetic flux values of the A1, A2, A3, and A4 winding turns are the same and the polarities are opposite. When the axial magnetic field first rotor 2 and the radial magnetic field rotor 5 continue to rotate, the permanent magnetic flux of the A1, A2, A3, and A4 winding turns periodically changes between positive and negative amplitudes, corresponding to the generation of an induced electromotive force with alternating amplitude and phase.
