Abstract: 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.

Abstract: 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 at least five transmitter coils, which are distributed around the rotational axis. Each of the transmitter coils is arranged in a sector around the rotational axis. An iron-core element non-rotatably connected to the second machine element is disposed in the form of a sector opposite the transmitter coils. In one step of the method, electrical primary voltage pulses act on the individual transmitter coils. The primary voltage pulses induce a secondary voltage pulse in each case in at least one other of the coils. One of those transmitter coils, the sector of which is only partially covered by the iron-core element, is selected.
