三级式无刷同步电机转子初始位置估算方法
Initial rotor position estimation of three-stage brushless synchronous motors
摘要
Abstract
A method of estimating the initial rotor position of a three-stage brushless synchronous motor at standstill without any position sensors was presented. Based on the magnetic saturation characteristics of the stator core, the preliminary initial rotor position of the machine was estimated by applying specified voltage vectors to the main generator and comparing the stator current values. Then, the stator current values were modeled using the preliminary initial rotor position information and Gaussian curve fitting was performed. The results show that the standstill rotor position is within 0.5° in electrical angle.关键词
