<p>A brushless permanent magnet motor with an axially-adjustable stator iron core coil, and a control system thereof. The motor comprises: a motor shell (1), a permanent magnet rotor (3), and a stator iron core coil (4) which is axially movably installed on the inner wall of the motor shell. The system comprises: the motor (1), an AC/DC rectifying unit, a control unit and a voltage sampling unit, wherein the voltage sampling unit collects the output voltage of the AC/DC rectifying unit and transmits the output voltage to the control unit, and the control unit controls the output quantity of a servo drive unit. By way of axially moving the position of the stator iron core coil (4) with respect to the permanent magnet rotor (3), the coil effective magnetic flux of the stator iron core coil (4) is changed. In combination with the fact that the position of the stator iron core coil (4) is controlled by the control unit in a power supply control system by collecting the voltage output quantity of the motor, feedback adjustment is performed on the power generation output of the motor, such that stable voltage and power output during electricity generation of the brushless permanent magnet motor can be realized under the condition where the rotating speed of the motor rotor is higher than a rated rotating speed and varies dynamically.</p> |
