摘要： The invention relates to a method and system for calibrating a control device, in particular an inverter control device, of an electric motor, comprising operating the electric motor as part of a force flow; performing a force measurement by means of piezo elements which are arranged in the force flow in such a way that the force flow is applied, in particular exclusively, to the piezo elements; and adapting a control characteristic the control device on the basis of at least one force component derived from the force measurement, in particular a change in the at least one force component and/or at least one torque component derived from the force measurement, in particular a change in the torque component.
