【产品】针对圆环多对极式编码器研发的霍尔效应芯片MLX92215,提高磁编码器分辨率以及精度
为了提高磁编码器的分辨率以及精度,迈来芯公司针对圆环多对极式编码器研发的第二代霍尔效应MLX92215芯片。MLX92215芯片是基于混合信号设计CMOS技术,可以推广到多极对磁钢旋转速度的检测项目中。
采用多极对磁钢,则磁钢在旋转一周过程中,霍尔感应到多周期正选信号,为实现编码器的绝对角位移测量,则要对每个周期信号进行编码,即为编码器的霍尔芯片输出信号。编码器磁钢各段沿半径方向平行充磁后,编码器磁钢外表面磁性为N/S极,对磁钢状态的改变一次进行编码。如果编码器的编码越多,代表该编码器精度越高。在编码器行业中,对磁钢的编码过程即为细分过程。对霍尔器件的原始信号进行高倍细分是可以提高编码器模块的精度。而MLX92215恰恰符合这样的应用。
