摘　　要：对无刷同步电机的励磁关系进行了详细推导,确定了无刷同步电机起动系统的励磁方案,提出了自控式无刷同步电机的起动控制方法并给出了电磁转矩方程。针对无刷同步电机起动的特点和电机的参数,确定了频率自控式的矢量控制作为控制起动系统的控制方法。通过仿真研究,电机的电磁转矩都保持稳定,电机转速稳定在500 r/min,实现了无刷同步电动机的快速、平稳起动。The excitation relationship of brushless synchronous motor is deduced in detail in this paper. The excitation scheme for the starting system of the brushless synchronous motor is determined. The starting control method of selfoperated brushless synchronous motor is put forward and the electromagnetic torque equation is given. According to the starting characteristic of brushless synchronous motor and the parameters of machine,the frequency control of vector control is determined as the control method. It can be seen that electromagnetic torque of the motor is stable and the motor speed is stable in 500 r / min. Rapid and smooth starting of brushless synchronous motor is realized.
