摘　　要：设计了一种基于正交编码原理并利用电感式接近开关获取位置信号的直线电机动子位置检测系统。该系统利用编码器和传感器模块感应动子运动并输出正交信号,不同传感器模块输出的位置信号由控制模块通过"或"运算进行整合,最后利用正交编码算法计算动子位置。通过实际平台的搭建和测试验证了该方案的可行性。该系统结构简单,可靠性强,适用于恶劣工况下的大型直线电机系统的位置检测。T his paper proposes a position sensing system for the liner motor that can obtain the posi-tion signals from the two inductive approach switches based on the quadrature encoding principle .The system uses the encoder and sensor blocks to induce the shuttle to move and transmit quadrature sig-nals .The signals from the different sensor blocks are combimed by oring in the controlling block and then transmitted into the computing center .With the quadrature signals ,the shuttle position can be calculated by the quadrature encoding algorithm .T he proposed system ,w hich is simple and reliable , is suitable for the linear motor working in rough environmental conditions .
