Abstract

See full text

The present invention relates to a method of operating a three-or more-stranded electronically commutated motor which, to detect its rotor position, has a number of sensors which is fewer, by at least one, than the number of sensors intrinsically necessary for this number of strands for controlling the commutation, having the following steps: (a) within each range (120) of rotor positions in which an adequate association between sensor output signals and position is possible, a virtual rotor position signal (H3B') is derived from the output signals (H1, H2) of said rotor position sensors (37, 38), as a replacement for a sensor which is not present;
