摘要
转矩控制技术是PMSM(永磁无刷同步电机)的核心技术。文章通过对直流电机电磁转矩概念的介绍,以及PMSM电机作用机理的理解,引出PMSM三相坐标系,并建立简化的两相坐标系模型。由两相静止坐标系引出两相旋转坐标系的模型,并推导出旋转坐标系下的电压及电流,从而推导出PMSM电机的转矩公式。
Torque control technology is the core of the all-digital fuzzy(brushless permanent magnet synchronous motor)technology.This paper introduces the concept of electromagnetic torque of dc motor,and the understanding of the mechanism of all-digital fuzzy motor,which leads to the all-digital fuzzy three-phase coordinate system,and to establish a simplified model of two phase coordinate system by two-phase static coordinate system model of two phase rotating coordinate system.Derivation and rotating coordinate system is deduced under the voltage and current,thus all-digital fuzzy motor torque formula is deduced.
