Abstract：In order to expand applications of permanent magnet synchronous motors (PMSM) in low cost electric drive systems,based on the analysis of hall position estimation principle,a design scheme for rotor position estimation of PMSM using two orthogonal locked hall effect position sensors is presented.The principle errors and the fixed errors caused by hardware installation are analyzed in this paper.Finally,the rotor position detection software design and the closed loop control of PMSM are realized on a STM32 micro controller.All experimental results show that two phase orthogonal hall position sensors for rotor position detection can obtain better position accuracy,has high performance price ratio,and can be applied in the motor control on the occasions of cost demanding.
