摘要： An integrated hybrid rotary assembly is configured to provide power, torque and bi-directional communication to a rotatable sensor, such as a lidar, radar or optical sensor. A common ferrite core is shared by a motor, rotary transformer and radio frequency communication link. This hybrid configuration reduces cost, simplifies the manufacturing process, and can improve system reliability by employing a minimum number of parts. The assembly can be integrated with the sensor unit, which may be used in vehicles and other systems.

摘要： A method for manufacturing a rotor for an electric machine with a contactless power transmission system, wherein an end winding cover is arranged on one end face of a laminated core of the rotor. The invention provides that a secondary unit (SEC) of the power transmission system is integrated in the end winding cover and, as a result, after the end winding cover has been arranged, the secondary unit (SEC) is held on the rotor indirectly via the end winding cover.

摘要： A rotary joint includes a first part and a second part configured to rotate around a rotation axis against the first part. The first part has a first magnetic core, a sliding brush, and a capacitive data link component. The second part has a second magnetic core for coupling power with the first magnetic core, a sliding track for galvanic coupling with the sliding brush, and a second capacitive data link component to transfer data from and/or to the first capacitive data link component. To weaken magnetic stray fields from the magnetic core, the rotary joint is a disc-type rotary joint, and the sliding track is arranged radially between the second magnetic core and the second capacitive data link component.

摘要： Aspects of the present disclosure are generally directed to using a rotary transformer to transfer power for a wind turbine generator. Certain aspects of the present disclosure are directed to a multi-rotor wind turbine. The multi-rotor wind turbine generally includes a plurality of rotors, a plurality of electrical generators, each coupled to one of the plurality of rotors, and one or more rotary transformers configured to transfer power between the electrical generators and a power grid. In some aspects, each rotary transformer comprises a first winding coupled to one or more electrical generators of the plurality of electrical generators, and a second winding magnetically coupled to the first winding and coupled to the power grid, wherein the first winding is rotatable with respect to the second winding.
