Abstract: A system and method for estimating a power output of an electric motor with at least one magnetic field sensor includes providing magnetic field signal data, providing magnetic field frequency data based on the magnetic field signal data, determining a fundamental harmonic frequency of the supply frequency and at least one further frequency, determining a ratio between an amplitude of the at least one further harmonic frequency and an amplitude of the fundamental harmonic frequency, providing reference ratio data describing a relation of a ratio between an amplitude of the at least one further harmonic frequency and an amplitude of the fundamental harmonic frequency and a power output of the electric motor, and estimating the power output of the electric motor based on the reference ratio data and the determined ratio.
