<p>The invention relates to a method for determining the actual angle position of a rotatable magnetic component in an electric drive (10) having an odd number of pole pairs. An actual angle measurement value (φAMR,k) of the rotatable component is measured using an angle sensor (28) which only measures the actual angle measurement value (φAMR,k) within a predefined reduced angular area, and an associated device (20) for determining an actual angle position of a rotatable magnetic component in an electric drive (10). According to the invention, the actual angle measurement value (φAMR,k) measured exclusively for the reduced angular area is converted using the direction and the sign of the magnetic field of the rotatable magnetic component in a clear angular position in non-reduced angular area, the direction and sign of the magnetic field of the rotatable magnetic element (12) being determined by applying first test impulses (Ua, Ub, Uc) to the electric drive (10) and by evaluating the resulting second test impulses (I1, I2, Ia, Ib, Ic) which are produced in the electric drive (10) in reaction with the applied first test impulses (Ua, Ub, Uc).</p> |
