Abstract
A powertrain system includes an input element, an output element, and a magnetic transmission stage disposed directly at the output element. The magnetic transmission stage includes a first rotor with a first number of pole pairs, a second rotor with a second number of pole pairs, the second number of pole pairs being different from the first number of pole pairs, a third rotor with a number of pole bars arranged such that the magnetic field between the first and second pole pairs is modulated. A mechanical transmission stage is disposed between the magnetic transmission stage and the input element in the powertrain, and a control means controls a power flow between the input element and the output element. The control means is connected to a rotor of the magnetic transmission stage and to a shaft of the mechanical transmission stage.
