The motor driving system comprises a motor and a plurality of rotor blades, the motor is a single-stator four-rotor axial magnetic flux motor, the stator is located in the middle, a first modulation rotor and a first permanent magnet rotor are arranged on the left side of the stator, the first modulation rotor is located between the first permanent magnet rotor and the stator, and a second modulation rotor is located between the first permanent magnet rotor and the stator. A first modulation rotor and a first permanent magnet rotor are arranged on the right side of the stator, a second modulation rotor and a second permanent magnet rotor are arranged on the right side of the stator, the second modulation rotor is located between the second permanent magnet rotor and the stator, the first permanent magnet rotor is fixedly connected with a first rotor blade through a first rotating shaft, and the first modulation rotor is fixedly connected with a second rotor blade through a second rotating shaft; the second permanent magnet rotor is fixedly connected with a third rotor wing blade through a third rotating shaft, the second adjustable magnetic rotor is fixedly connected with a fourth rotor wing blade through a fourth rotating shaft, the thrust airflow directions generated by the four rotor wing blades are the same, the four rotor wing blades rotate at the same time so that larger thrust can be generated, and the power density of the motor is high.

    本发明公开一种旋翼无人机用电机驱动系统,包括电机与多个旋翼叶片,电机为单定子四转子的轴向磁通电机,定子位于中间,定子左侧设置有一个第一调制转子与一个第一永磁转子,第一调制转子位于第一永磁转子与所述定子之间,定子右侧设置有一个第二调制转子与一个第二永磁转子,第二调制转子位于第二永磁转子与所述定子之间,所述第一永磁转子通过第一转轴固定连接第一旋翼叶片,所述第一调磁转子通过第二转轴固定连接第二旋翼叶片,所述第二永磁转子通过第三转轴固定连接第三旋翼叶片,所述第二调磁转子通过第四转轴固定连接第四旋翼叶片,四个所述旋翼叶片产生的推力气流方向相同,四个旋翼叶片同时旋转能够产生更大的推力,电机的功率密度较高。
