Power train including first electric motor and planetary gear mechanism, and wind energy equipment, gas turbine, hydro turbine, and automobile including the power train
Power train including first electric motor and planetary gear mechanism, and wind energy equipment, gas turbine, hydro turbine, and automobile including the power train
A drive train, wherein the drive train has a first electric machine (EMI) which can be operated in a motor or generator operating state, and a planetary gear mechanism (100) having a rotational-speed changing apparatus, wherein the rotational-speed changing apparatus is configured, in particular, as an internal gear (110) and/or as a planetary gear (114) and/or as a sun gear (112), wherein the planetary gear mechanism (100) has a drive side and a driven side, characterized in that the first electric machine (EMI) engages into the rotational-speed changing apparatus in a controlling manner in the motor or generator operating state, with the result that a step-up transmission ratio is formed in the planetary gear mechanism (100).
