An installation for an electric motor includes an electrical energy source with elements of different technologies and an inverter for controlling an AC electric motor. The inverter includes an AC current generator for delivering current to a terminal strip to be connected to phases of the electric motor, a supply line, current sensors on certain phases supplying the electric motor, a current sensor on the supply line, an input for receiving information that includes a limit current of the source and a requested-torque setpoint, and a controller for controlling phase currents of the electric motor as a function of the setpoint while maintaining a current of the supply line at an acceptable value as a function of the limit current of the source. The installation makes it possible to impose a maximum current on the current generator without risk of impairing the current generator. |
