Abstract
A single-strand EC motor with a winding strand with two winding connections, has a current regulating device in the winding strands between the winding connections. The current regulating device regulates the winding current of the single-strand EC motor during a first commutation phase with a positive current flow and a second commutation phase with a negative current flow. In each case, at a constant value. The value of the average output voltage uw(t) of the current regulator is used to ascertain the commutation time.
