【应用】角度分辨率10bit~16bit的三轴霍尔传感器实现伺服电机精准定位

时间： 2017-10-26 来源：世强作者：潇湘子

技术问答

伺服电机（servo motor ）是指在伺服系统中控制机械元件运转的发动机，是一种补助马达间接变速装置。

伺服主要靠脉冲来控制转动，伺服电机接收到1个脉冲，就会旋转1个脉冲对应的角度，从而实现转动位移；伺服电机本身有编码器能反馈端子位置，伺服电机每旋转一个角度，编码器都会发出对应数量的反馈信息，这样，反馈信号和伺服电机接受的脉冲形成了闭环控制。通过控制脉冲及反馈信号，伺服系统就能够很精确的控制伺服电机的转动，实现精确的定位。

从伺服控制原理上可以看出编码器是伺服控制器的重要部件，编码器的精度直接决定伺服电机的精度。目前主流的伺服电机转速从1000到5000rpm，角度分辨率在8-12bit。

磁编MLX90380方案，结构简单，仅仅需要一块径向通磁的小磁铁，加上MELEXIS的MLX90380三轴霍尔传感器芯片就能实现编码输出功能。且安装方式灵活，对应XY、YZ、XZ有三种安装方式。

MLX90380支持的磁铁转动速度为0-25000rpm，这个转速远远满足于伺服电机的转速要求。

MLX90380的输出为sin&cos正余弦原始信号，通过MCU的ADC采用处理；角度分辨率可调，目前10bit~16bit的ADC在MCU中有集成，不需要外加高精度ADC就可以实现8~12bit的精度要求。

磁编MLX90380方案的基本构件为MLX90380外加磁铁，是一款低成本磁编码器方案，很适用应用于伺服电机中。

目前我看用Allegro和英飞凌的，不知道MLX90380有没有人用过？MLX支持怎样？
- 用户97967577_世强回复： Melexis品牌的磁编传感器MLX90380，输出是正余玄波信号，可以应用在25000转速的电机上，识别出电机位置，工程师实测MLX90380的温漂明显好于Allegro和英飞凌的芯片。目前Melexis在上海有自己的FAE团队，同时世强先进是Melexis的代理商，所以你选择MLX90380，会同时得到Melexis和世强两个team的FAE来支持。
