无刷直流电机在很多应用中对速度和转矩的测控技术要求比较高,要求速度和转矩恒定输出,但是两者存在相互制约的矛盾,难以实现在速度、转矩的恒定可调。以口腔种植机为研究对象,经过比对国外标准口腔种植机的技术指标,提出了双闭环测控方案。实现了速度恒定输出的同时,转矩在一个滞回误差内也稳定输出。由于口腔种植机本身的结构局限,对于扭矩的测试与控制是一难点,采用的是直接测控定子磁链的方法来实现扭矩的测控。

Brushless DC motor needs a higher requirement about the control technology of speed and torque in many appli‐cations ,to achieve a constant output of speed and torque ,but there is a contradiction between the two mutual restraints , it is difficult to achieve in terms of speed ,torque adjustable constant .In oral planting machine for the study ,after more than a standard oral planter on foreign technical indicators ,proposed dual‐loop measurement and control solutions .To achieve a constant output speed ,w hile the torque can be achieved in a stable output hysteresis range .Due to the struc‐ture of the limitations of Oral Implantology machine itself ,for torque testing and control is a major difficulty ,this paper is a direct method of controlling the direct control of the stator flux to achieve torque .
