A driver unit for a rotary encoder is fastened to the end face of the slip ring body and/or to the axial end of the rotor shaft and electrically insulated from the connection adapters. A centrifugal force support ring is arranged on the end face of the slip ring body such that the connection adapters and the driver unit are arranged in a through-opening of the centrifugal force support ring.

A slip ring includes an essentially cylindrical contact region defined by a radius and having a contact region which faces in a radially outwards direction. The contact region has a recess in a region of the contact surface, with the recess configured to have a projection extending on an inner side of the recess and/or being interrupted in a tangential direction. The contact region has an annular surface formed with an opening which communicates with the recess and extends towards an axial direction at an incline at an interval of 5 degrees to 45 degrees with respect to a normal of the annular surface. At least two insulating regions are arranged axially adjacent to the contact region and each being defined by a radius, with the radius of the contact region being larger than the radius of the insulating region.

A computer-implemented method and system for transmitting power and data together in a rotorcraft using a slip ring assembly is disclosed. According to one example, a computer-implemented method includes providing a slip ring assembly comprising a stationary element coupled to an airframe of a rotorcraft and a rotatable element rotatable relative to the stationary element and coupled to a rotor assembly of the rotorcraft. Power is transmitted from a power source associated with the airframe to an electronic device associated with the rotor assembly, the slip ring assembly being configured to complete an electrical circuit between the power source and the electronic device to provide power from the power source to the electronic device. Data is transmitted from a first data transceiver associated with the airframe to a second data transceiver associated with the rotor assembly via the electrical circuit completed by the slip ring assembly.

There is provided a current transferring device for an electric machine comprising a rotary bearing member fixed in a rotor shaft and rotating with it and a non-rotary component. The rotary bearing member includes a first compartment filled with a conducting fluid and having a first opening and a rotor positive connector that is in electrical contact with the conducting fluid therein and electrically connected to a rotor positive pole, and a second compartment filled with a conducting fluid and electrically insulated from the first compartment and having a second opening and a rotor negative connector that is in electrical contact with the conducting fluid therein and electrically connected to a rotor negative pole. The non-rotary component closes the first and second openings.

An improved counter-rotating (CR) differential electric motor assembly is utilized to power an aircraft vehicle or fan for moving a gas and includes two oppositely rotating propellers that may be mounted to horizontal flight and vertical lift-off aircraft or a fan housing in spaces similar in size to mounting spaces for traditional motors having only one propeller and includes a hollow central shaft and slip ring assembly that is mounted either within, slight above, or total above oppositely rotating components and around the hollow central shaft.

A slip ring for transferring electrical signals between rotating and static elements of a device includes a rotating element, a static element, an electrical contact assembly, including a plurality of subassemblies, contacting the rotating element and static element, one subassembly including a deformable PCB, and a spring element positioned to supply an axially aligned force to a face of the PCB to facilitate electrical contact between the PCB and other electrical contacts elements on another subassembly.

The present disclosure relates to a smart generator and, more particularly, to a smart generator in which two stators are used for a single rotor, the gap between an N-pole and an S-pole of the first and second stators is decreased, and a load that is an interference electromagnetic force affecting a rotor wire is minimized, whereby more power can be generated from a less force.

A transport device can be moved over a floor in order to transport at least one object and/or one person by means of at least one rolling device (3). A drive element (4) can be rotated at least indirectly using the rolling device (3). The drive element (4) comprises at least two drive magnets (12).
