Abstract
An apparatus is provided for powering at least one electric motor. The apparatus includes at least one driving device for driving the electric motor, a supply path positioned between a supply voltage generator and the at least one driving device, a first circuit, a control device, and a protection device for protecting against over-voltages. The first circuit is inserted in the supply path to enable and prevent the powering of the at least one driving device, and the control device controls at least the first circuit. The protection device includes a second circuit for detecting a current that flows in the supply path from the at least one driving device to the supply voltage generator, and a third circuit for selectively absorbing the current that is detected.
