摘　　要：电机位置的检测精确程度会直接影响该电机系统的性能和效率.本文提出了一种基于磁性角度编码器MT6825的电机位置检测装置.装置采用STM32F103C8T6微控制器作为核心处理器,通过SPI接口与MT6825编码器进行数据传输.针对磁性编码器固有的迟滞特性,设计了角度数据补偿模块.实验结果表明,该检测装置能够准确可靠地测量电机转子的位置,并在低至中速的转速范围内保持较好的测量精度,为中低速电机的精确位置控制提供了一种可行且有效的解决方案.Prercise detection of motor position has a direct impact on the performance and efficiency of the motor system concerned.This article proposes a motor position detection device based on magnetic angle encoder MT6825.The device adopts the STM32F103C8T6 microcontroller as the core processor and transmits data with the MT6825 encoder through the SPI interface.In consideration of the inherent hysteresis characteristics of magnetic encoders,a module for angular data compensation is designed.The experimental results show that the detection device can precisely and reliably measure the position of the motor rotor and maintain high measurement accuracy in the low or medium angular velocity range,which provides a feasible and effective solution for precise position control with respect to low or medium angular velocity motors.
