Abstract

An electrical rotating machine includes a machine housing accommodating a rotor, and a stator. In order to allow the method to be carried out without structural changes to the electrical rotating machine a first physical value of the stator and a second physical value of the rotor are measured outside the machine housing, and a state variable of the electrical rotating machine is determined from the first physical value and the second physical value. The state variable, or alternatively the first and second physical value, are sent to a cloud, in particular wirelessly or by hardwired or optical means.
