A motor control device includes a signal identifying unit and an overvoltage detecting unit. The signal identifying unit includes an optical isolator that converts an electrical signal supplied via a terminal to which an external device is connected and a switch that turns off a connection circuit connected to the terminal. The overvoltage detecting unit is configured to turn off the switch when a voltage applied to the connection circuit is greater than a threshold voltage.

A method for operating an electric drive system is provided. For example, a controller retrieves from memory a predictive model indicating a predicted winding temperature associated with a known negative temperature coefficient (NTC) temperature, wherein the predictive model is based on historical NTC temperatures and historical winding temperatures, and one or more operating parameters. The controller receives current NTC information indicating one or more current NTC readings corresponding to one or more switching devices within the inverter. The controller determines an estimated winding temperature corresponding to the motor based on the predictive model and one or more current NTC readings and the current operating parameters. The controller provides instructions based on the estimated winding temperature to adjust the motor input.

The invention relates to an electrical generation method for supplying power to at least one electrical network of an aircraft using an electrical generation system, the aircraft comprising two power supply paths, each power supply path comprising an electrical converter and an electrical generator, the electrical system comprising two regulation units (21a) respectively associated with each power supply path, each regulation unit (21a) comprising a correction module (5) comprising an integral corrector (CI), the method comprising steps consisting, for the correction module (5), in: determining a power setpoint (PBP*), from a distribution voltage setpoint (VDC*) and from a measurement of the distribution voltage (VDC), determining a divergence indicator (M3) from a gradient (GPBP*) of the power setpoint (PBP*), and resetting the integral corrector (CI) of the regulation unit (21a) of the power supply path depending on the divergence indicator (M3).
