Abstract
A drive system (1) having a unipolar machine (2) and a fuel cell (3) for supplying the unipolar machine (2) with electrical energy. The fuel cell (3) can be arranged in a ring shape around a rotor shaft (5) of a rotor (4) of the unipolar machine (2). The unipolar machine (2) can be provided in a motor vehicle (600) to supply a traction torque.
Claims13
A drive system, comprising:
- a fuel cell including a first electrode and a second electrode;
- and
- a unipolar machine, the fuel cell being configured to supply the unipolar machine with electrical energy, the unipolar machine includes a rotor and a rotor shaft, and the fuel cell surrounds the rotor shaft of the rotor in a ring shape;
- wherein:
- the first electrode of the fuel cell is non-rotatably connected to the rotor, and the first electrode receives a first fuel supply via a rotary feedthrough and a channel to the rotor shaft and the rotor;
- and
- the second electrode of the fuel cell is connected to a stationary component of the drive system, and the second electrode receives a second fuel supply via a channel extending through the stationary component.
4 more elements
A drive system, comprising:
- a unipolar machine having at least one magnet, a rotor, and a shaft;
- a fuel cell configured to supply energy to the unipolar machine, the shaft including a channel for feeding fuel to an electrode of the fuel cell mounted on the rotor, wherein the at least one magnet comprises a plurality of magnets and the electrode is positioned fully radially outward of each of the plurality of magnets.
