摘　　要：为低成本检测永磁直线同步电机动子位置,课题组提出一种新型霍尔传感器检测装置。该装置由一个附加的辅助磁钢和霍尔传感器组成;通过霍尔元件检测电机动子磁场,利用磁场信息计算动子位置;分析霍尔元件检测过程中可能的误差影响,并使用JMAG进行有限元分析,依据分析结果选择最佳安装位置。结果表明:通过分析计算相邻传感器的检测结果可以检测电机动子位置。该装置可以满足低成本检测电机动子位置的需求。In order to detect the rotor position of permanent magnet synchronous linear motor at low cost, a new Hall sensor detection device was proposed. The device was composed of an additional auxiliary magnetic steel and a Hall sensor;The rotor magnetic field of the motor was detected by the Hall element, and the rotor position was calculated using the magnetic field information;The possible error influence in the process of Hall element detection was analyzed, and JMAG was used to conduct finite element analysis. The best installation position was selected according to the analysis results. The results show that the position of the motor can be detected by analyzing and calculating the detection results of the adjacent sensors. The device can meet the need of low-cost detection of the rotor position of the motor.
