Abstract

In an electronically commutated motor (M), rotor position signals are generated by means of a galvanomagnetic rotor position sensor (40).
A timer (CNT_HL) brings about an advanced commutation which occurs only once the motor has reached a specific rotation speed, and whose magnitude is a function of the rotation speed.
