1. A method for calibrating a control device of an electric motor, comprising:
operating the electric motor as part of a force flow;
performing a force measurement by piezo elements which are arranged in the force flow in such a way that the force flow is applied to the piezo elements; and
adapting a control characteristic of the control device on the basis of at least one of a force component derived from the force measurement or a torque component derived from the force measurement, wherein the control characteristic is adapted based on at least one criterion, wherein the at least one criterion comprises:
a torque rise time from 10% of a torque demand of the electric motor to 90% of the torque demand; or
an intensity of overshoot of a value of 100% of the torque demand.
