Abstract (en)
[origin: WO2019122224A1] The invention describes an electromechanical system for transferring rotational energy, torque and power in a powertrain, to which a first, a second and a third machine for energy conversion (2, 3, 4) are coupled, and a superimposed gearing (1) for a system of this kind having a planetary gearbox (7). The sun gear (8) of the planetary gearbox (7) is coupled by means of a first shaft (5) for transferring a torque to the first machine (2) and at least one planetary gear (9) is coupled by means of a second shaft (6) for transferring a torque to the second machine (3). The third machine (4) is designed as a three-phase synchronous machine. An internal gear (10) of the planetary gearbox (7) forms a rotor of the three-phase synchronous machine (4). The described technical solution is characterised in that the internal gear (10) is connected to a housing (15) of the planetary gearbox (7), and that permanent magnets (11) for exciting the three-phase synchronous machine are arranged, more particularly are fastened, on the internal gear (10) and/or on the housing (15) of the planetary gearbox (7).
