Abstract

A motor and a method for serves finding the position of an armature in relation to a stator of the motor. In the method and the motor the armature is driven by an exciting field which is produced by exciting windings of the stator, and the armature is caused by the exciting field to perform an oscillatory motion, whose progression is detected by a position measuring means for measuring positions of the armature and is evaluated to determine the relative position, with the steps of:
