The invention relates to a method for determining the position of the rotor of an electric machine (4) having multiple phases (1, 2, 3) in relation to the stator. According to the invention, the change ∆I in the time derivative I of the current I flowing through at least one of the power inputs (1', 2', 3') is determined, said change ∆I being caused by a change ∆U in the potential U on at least one of the power inputs (1', 2', 3') of the electric machine (4), and a measurement signal that is representative of a position of the rotor is determined from multiple simultaneously or successively determined changes ∆I. |
