Patents by Inventor Gernot STEINMAIR

Gernot STEINMAIR has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11634039
    Abstract: A system and method for integrated charging a vehicle includes a hybrid excitation machine, operable as a traction motor and including a rotor separated by an air gap from a stator with AC windings. An AC utility line power supply is connected to the AC windings providing an electrical current to the vehicle and inducing a magnetic flux across the air gap and in the rotor. A short circuit, an open circuit, or a DC voltage may be applied to a DC winding in the stator to reduce the magnetic flux into the rotor. A field coil in the rotor may be excited with a DC voltage using a secondary coil on the rotor in a traction mode. The secondary coil is excited by the stator windings using field-oriented control in a “self-excited machine” embodiment, and is directly excited by a separate primary coil in an “externally-excited machine” embodiment.

  • Patent number: 10788050
    Abstract: An electric compressor for compressing a gas, particularly configured for use in a motor vehicle, comprising a control unit, an electric motor controlled by the control unit, a compressor wheel driven by the electric motor, and a housing at least partially surrounding the electric motor. The housing is produced by an encapsulation method such that a cooling structure is formed integrally with the housing, in particular within the housing, for ensuring cooling of the electric motor and of the control unit. A method for producing the electric compressor of this kind is also disclosed.

  • Patent number: 10676046
    Abstract: A vehicle has a wiring harness and a substantially electrically non-conductive body. The vehicle has at least one ground point. At least one bus bar is associated with the wiring harness. The at least one bus bar is associated with the at least one ground point. The ground point is electrically connected to the bus bar, and the bus bar is mechanically fixed in the vehicle.
