1. A method for measuring an angle between a first machine element and a second machine element that rotates about a rotational axis relative to the first machine element, the method comprising:
locking a plurality of coils are locked in rotation with the first machine element, the plurality of coils comprise at least five transmitter coils that are distributed about the rotational axis and are each arranged in a sector about the rotational axis, locking an iron core element in rotation with the second machine element, the iron core element is in a form of a sector about the rotational axis opposite the transmitter coils, such that as a function of the angle to be measured, the sectors of the transmitter coils are each covered with a percentage between 0% and 100% of the respective sector by the iron core element, loading the individual transmitter coils with primary voltage pulses, wherein through the primary voltage pulses, a secondary voltage pulse is induced in at least one of the other coils, allocating the secondary voltage pulses to one of the transmitter coils and wherein amplitudes of the secondary voltage pulses are each dependent on a percentage of coverage of the sector of the respectively allocated transmitter coils by the iron core element, and selecting one of the transmitter coils with the sector thereof covered only partially by the iron core element starting from a comparison of the amplitudes of the secondary voltage pulses, and determining the angle to be measured starting from a ratio formation between the amplitude of the secondary voltage pulse allocated to the selected transmitter coil to an amplitude maximum and by a reference to the sector of the selected transmitter coil. |
