Abstract: A rotating machine assembly includes a rotating machine that has a cover that defines an outer surface of the rotating machine and a stator disposed within the cover. The stator is stationary with respect to the cover. The rotating machine also includes a shaft rotatably disposed at least partially within the cover so as to define a rotation axis. The shaft Includes a first end that is connectable to an aircraft engine and a second end that is opposite the first end. The rotating machine also includes a rotor attached to the shaft, the rotor being movable with respect to the stator and a power module including at least one MOSFET that periodically reverses an electrical current direction of the rotor. The power module includes the at least one MOSFET Is disposed within the cover.

Abstract: Rechargeable batteries are used as a power supply in the most varied electrical devices. Parallel to this, connections with other energy sources are frequently available, at least for part of the time, in order to charge the rechargeable batteries during this time. Particularly efficient lithium ion batteries have the problem that short charging/discharging cycles cause them to age just as much as long cycles, during which the user can derive greater benefit from them. It is the task of the invention to ensure particularly effective use of rechargeable batteries during charging/discharging cycles of the most varied duration. This is achieved in that the rechargeable battery is divided into cells, of which only one is charged, in each instance, and the others stand ready to provide energy. If the network voltage stops, charging of the cell just being charged is completed from the other cells.
