In a device for diagnosing a mechanical system driven by an electric drive motor, the drive motor thereof, and the shifting device thereof include at least one sensor for detecting the current curve in a conductor of the electric connection of the drive motor. The precision and the degree of detail of the diagnosis are to be improved compared to the prior art and expanded to include the drive motor and the shifting device in order to improve the efficiency and aim of the maintenance process carried out in response to the diagnosis. This is achieved in that the device additionally has sensors for detecting the voltage curves in the conductors of the electric connection of the drive motor, wherein each conductor is paired with a sensor for detecting the current curve and with a sensor in interaction with a sensor in order to detect the voltage curve.

A variable speed drive comprises an output for delivering a drive voltage to an electric motor, power inverter, a drive controller, and a current sensor. The drive controller includes a PWM generator, a control law module, and a state variable estimator for estimating a state variable of the electric motor. The module computes a target voltage signal based on state variable estimates provided by the estimator and outputs the target voltage signal to the PWM generator. The generator approximates the target voltage signal with a PWM control signal, controls the inverter using the control signal, computes, based on the deviation between the control signal and the target voltage signal, an estimation support signal, and outputs the estimation support signal to the estimator. The estimator estimates a state variable of the motor based on the estimation support signal and the drive current, and outputs the estimate to the module.
