In a method for commutating an electronically commutated motor, a predictive calculation is made of a first time span that the rotor will need in order to pass through a specified rotation angle that lies between a first rotational position (&part;0) and a later second rotational position (&part;1) at which a switching operation is to be effected in the motor. Upon actual passage through the first rotational position, a reference time is identified and stored. The time difference between the present time and the stored reference time is then monitored repeatedly and compared to the first time span; and when a specified relationship exists between the time difference and the first time span, the switching operation is performed.
