Abstract

A reversible electrical machine () comprising: a first electrical device () having a first stator () and a first rotor (); a second electrical device () including a second rotor () and a second stator () together with an outlet shaft () and first disengageable coupling means () enabling said first and second rotors () to be associated and dissociated in rotation. Said reversible electrical machine () also includes second disengageable coupling means () that are disengageable under a predetermined force and that mechanically connect said second rotor () to said outlet shaft (). Said first electrical device () is a motor for transmitting high mechanical power to said outlet shaft (), while said second electrical device () is a motor-generator for operating in motor mode to transmit additional mechanical power to said outlet shaft (), and in generator mode for receiving mechanical power from said outlet shaft ().
