Abstract

The invention relates to a method wherein the speed of the rotor of an electronically commutated synchronous machine is determined or controlled by means of one or more rotor position sensors, in particular, three rotor position sensors that are fixed to the stator, and a time measuring device, wherein the angle traveled by the rotor and the time lapsed during the travel are measured, wherein the measured angle traveled by the rotor is corrected by means of one or more first correction constants, in particular a differential for correcting for the influence of non-uniform positioning or expansion of the position marking of the rotor, and a circuit configuration for actuating an electronically commutated synchronous machine.
