A process for the direction of rotation of the detection of an at least one pointer of a watch driving stepping motor

摘要

The present invention relates to a method for detecting the rotation of a a rotor with a motor coil and having at least one pointer of a watch driving stepping motor, in which a drive voltage pulse (1) as well as a first detection voltage pulse (3) to the motor coil are output and on the basis of a first pulse response to the first detection voltage pulse (3) the position of the rotor is determined. According to the invention, it is provided that a second detection voltage pulse (4) with to the first detection voltage pulse (3) of opposite polarity to the motor coil is output and a second pulse response to the second detection voltage pulse (4) in addition to determining the position of the rotor is used and / or that a the first detection voltage pulse (3) a preceding stabilization voltage pulse (2) with to the drive voltage pulse (1) of opposite polarity to the motor coil is output.
