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. |
