旋转角度传感器

The AKM rotation angle sensor enables the measurement of magnetic fields in parallel to the chip surface and can detect the absolute angle of a magnetic field.

产品

AKM的旋转角度传感器芯片由硅片上的霍尔元件和信号处理电路组成。是一种单片集成的磁性旋转角度传感器。

该传感器输出的是在集成电路表面水平施加磁场的绝对角度。由于采用了偶极子径向磁铁和磁汇聚板的横向磁场检测方法,因此具有很好的抗轴向错位能力。

该传感器可以通过一个小磁铁和一个IC的简单配置,轻松实现消费类、工业类和汽车类应用的非接触式旋转角度传感器。

带有故障检测功能
14位旋转角度传感器

AK7455

AK7455是一款14位绝对旋转角度传感器,适用于离轴应用,具有内置角度误差修正功能。 

AK7455还有将传感器磁体以外的磁场作为异常磁场进行识别的功能,有助于系统异常和故障的检测。

新传感器除了传统产品的X-Y平面的磁场检测外,还可以检测离轴配置 (Off-Axis) 的X-Z和Y-Z平面的磁场,从而提高了传感器在电机系统中放置的自由度。

与以往产品相比,扩大了角度计算电路的带宽设置,提高了电机加减速时角度检测的响应速度。
