Abstract
Official abstract text for this publication.
An arrangement is provided having an oscillating motor, a control circuit for controlling the motor, a sensor arrangement for determining an electric characteristic of the motor at a predetermined measuring time or in a predetermined measuring position during an oscillation process, and a processor for determining a movement variable of the motor by means of at least the electric characteristic and a constant inductivity value of the motor. The control circuit in the operating state controls the motor as a function of the movement variable, and the measuring time or the measuring position is predetermined such that the inductivity of the motor remains approximately constant at least in a given current interval, even with different currents through the motor.
First claim
Opening claim text (preview).
What is claimed is: 1. An arrangement having an oscillating motor having one or more stator coils, a control circuit to control the motor, one or more connecting lines that connect the control circuit to said one or more stator coils, creating a stator coil connection; wherein the control circuit uses the stator coil connection to determine an electric characteristic of the motor at a predetermined measuring time or in a predetermined measuring position during an oscillation p…
