A method and circuit arrangement for controlling the commutation of coil sets of a direct current motor with a fixed sensor, in which a sensor signal (S1) having a first period (T1) related to the speed of rotation of the motor rotor is generated during each revolution of the rotor, including the steps of: producing a control signal having a period equal to the sum of the first period (T1) and a second period (T2) proportional to the first period (T1); and at the end of the period of the control signal, starting commutation of a first one of the coil sets.
