Abstract
The invention relates to a method for generating acoustic feedback of an orthopaedic device comprising at least one electric motor (13), which has a stator (30) and a rotor (40) which can rotate about a rotational axis (50) and is coupled to a component of the orthopaedic device, which component can be moved by the electric motor (13), wherein the electric motor (13) is oscillatingly operated by repeated pole changing of at least one motor voltage, without the rotor (4) performing a complete rotation about the rotational axis (50).
Claims13
A method for generating acoustic feedback of an orthopedic device comprising at least one electric motor comprising a stator and a rotor configured to rotate about an axis of rotation and wherein the rotor is coupled to a component of the orthopedic device which is adjustable by the electric motor, the method comprising the steps of:
- operating the at least one electric motor in an oscillating manner by repeated reversal of a polarity of at least one motor voltage, and
- rotating the rotor about the axis of rotation but without the rotor performing a complete rotation about the axis of rotation.
An orthopedic device, comprising:
- at least one electric motor comprising a stator and a rotor, wherein the rotor is rotatable an axis of rotation, and wherein the rotor is coupled to a component of the orthopedic device which is adjustable by the at least one electric motor;
- a control device connected to the at least one electric motor, wherein the control device is set up to repeatedly reverse a polarity of at least one motor voltage of the at least one electric motor to generate an acoustically perceptible signal, without the rotor performing a complete rotation about the axis of rotation.
