目前永磁同步电机有驱动算法复杂、可选择的芯片范围较窄以及可运用的数字信号处理器芯片成本较高等问题,针对上述问题,采用一种新的驱动算法对永磁同步电机进行了研究,并且将永磁同步电机运用到电梯门机控制系统中。如果运用这种新的驱动算法,既能满足电梯门机系统对精确度的要求,又能大大降低工程花费成本。利用所提出的永磁同步电机新的驱动算法,简化了算法,并利用飞利浦公司LPC1752芯片实现,给出了实验输出的电流波形,表明所提出新的驱动算法实施的有效性。 At present, PMSM has many problems such as complex driving algorithm, narrow chip range and high cost of digital signal processor chips. In view of the above problems, a new driving algorithm is used to study PMSM , And the permanent magnet synchronous motor is applied to the elevator door control system. If we use this new driving algorithm, both to meet the elevator door system accuracy requirements, but also greatly reduce project cost. By using the new driving algorithm of the PMSM, the algorithm is simplified and the LPC1752 chip of Philips is used. The experimental results show that the new driving algorithm is effective.
