用于无接触测量角度的方法和角度传感器
摘要：
本发明涉及一种用于测量在第一机械元件和可相对于其旋转的第二机械元件之间的角度的角度传感器和方法。多个线圈(02，03，04，06，07，08)抗转动地与第一机械元件连接，所述多个线圈包括至少五个围绕旋转轴线分布的发射线圈(02，03，04，08，07)。每个发射线圈(02，03，04，06，07)在一个扇区中围绕旋转轴线设置。与第二机械元件抗转动连接的铁芯元件(00)以扇区的形式与发射线圈(02，03，04，06，07)相对置。在方法的一个步骤中，对各个发射线圈(02，03，04，06，07)加载电的初级电压脉冲。通过初级电压脉冲分别在至少一个另外的线圈(08)中感生次级电压脉冲。选择如下发射线圈(03，06)，所述发射线圈的扇区仅部分地被铁芯元件(00)覆盖。基于在与所选择的发射线圈(06)相关联的次级电压脉冲的振幅与振幅最大值之间的比例形成来确定要测量的角度。
摘要（英）：

A method and an angle sensor for contactless measurement of an angle between a first machine element and a second machine element rotatable with respect thereto. A plurality of coils are non-rotatably connected to the first machine element and include transmitter coils—distributed around the rotational axis. Each of the transmitter coils is arranged in a sector about the rotational axis. An iron-core element non-rotatably connected to the second machine element is disposed in a sector opposite the transmitter coils. Based on applying voltage pulses, a determination of the angle to be measured is effected starting from a ratio formation between the amplitude of a secondary voltage pulse associated with a selected transmitter coil and a peak amplitude.
