    摘要： A slip ring body for electrically contacting an asynchronous machine includes first and second slip rings rigidly connected to one another, with at least two conductor bars fastened to each of the slip rings. At least one of the slip rings has a recess for passage of the conductor bars of the other slip ring and defining around the recess a first region in which air is at least partially present and which has a magnetic conductivity that is lower than a magnetic conductivity in a second region in which the conductor bars to the one slip ring are fastened, or which second region is embodied for contacting with an energy-transmitting brush. The first and second regions are not made of copper. The recess defines an opening cross-sectional area which is greater than a cross-sectional area of the conductor bars fastened to the one slip ring.

    摘要： A slip ring, in particular for use in a wind turbine, includes an axle extending in an axial direction and a contact region having a contact surface on a peripheral surface of the contact region and a recess extending in a tangential circumferential direction along the peripheral surface. The contact region includes an axial end face formed with an opening which communicates with the recess. The contact region includes three essentially cylindrical segments which define two covering segments and an intermediate segment arranged in a center between the two covering segment. Each of the two covering segments defines a radius which is larger than a radius of the intermediate segment so that a peripheral surface of the intermediate segment forms an underside of the recess. An insulating region is arranged adjacent to the contact region on the axle.

    摘要： A rotor for a rotating electric machine includes a rotor winding arranged for conjoint rotation on a rotor shaft, and a slip ring body arranged on an axial end of the rotor shaft and having an end face on an axial end of the slip ring body opposite to the rotor winding. The slip ring body includes connection adapters which project axially beyond the end face of the slip ring body for connection of line ends of the rotor winding. 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.
