Device with electrical machine and method for determining a value correlated with a torque of an electrical machine

摘要

The invention relates to an apparatus (100) with an electrical machine (114) which is set up to determine a current in the electrical machine (114) and at least one physical measured quantity influencing a relationship between current and torque of the electrical machine, and taking into account the at least one measured variable from the current to determine at least one correlated with a torque generated by the electric machine (114) torque, and a method for determining such a size.
