摘要： A rotor of a dynamo-electric rotary machine includes a rotor core arranged concentrically to a rotor axis and including slots filled with electrically conductive material. A front ring is arranged at a front axial end of the slots and includes electrically conductive material, and a rear ring is arranged at a rear axial end of the slots and includes electrically conductive material. A rotor-core-distal surface of the front ring and/or rear ring has a bevel in axial direction from an outer circumference to an inner circumference, with the bevel defined by a bevel angle having a value of 3° to 30°. A support element is at least partially connected to the front and/or rear ring with a positive fit and pressed thereon axially, with the support element being supported on a shaft and having a radial end which terminates at a radial end of the front and/or rear ring.

摘要： A component for an electric machine includes a flat region in which an electric line runs when the component is integrated into the electric machine and which includes a sharp edged structure. A polymer layer adheres to the flat region without further aid such as to mask the sharp-edged structure and thereby protect from damage the electric line on the flat region. The polymer layer is made of cured plastic adhesive and jetted onto the flat region in the form of threads, such that the threads are spin-coated on top of one another in the form of overlapping loops and form a network structure which spans the sharp-edged structure.

摘要： An electric machine includes a stator, a rotatably mounted rotor interacting with the stator and including a shaft which has an axial borehole. A flow guiding element extends into the axial borehole such as to enable a coolant to flow out of the flow guiding element and into the axial borehole or into the flow guiding element and out of the axial borehole. A slide ring seal seals the shaft with the axial borehole with respect to an element that is rotationally stationary relative to the shaft. When the electric machine is in operation, a value for moisture in a cavity of the electric machine can be determined in a cavity of the electric machine.

摘要： A rotor for an electrical machine includes a laminated core with stack of sheets extending in an axial direction from a first axial end to a second axial end. The stack of sheets has layered layers in the axial direction. Each layer has a plurality of sheet areas with flow conduction blocks situated between adjacent sheet areas. At least one flow conduction block is cast with a non-ferromagnetic potting compound. The potting compound extends in the at least one flow conduction block from the first axial end to the second axial end. Fastened sheet areas, respectively, having at least one web protrudes into the potting compound. The protruding web, at least in part, extends in a direction, having a component in the axial direction. In each layer, at least one sheet area is a fastened sheet area.

摘要： A self-ventilated electrodynamic rotary machine includes a housing configured to at least partially axially enclose the rotary machine, and a fan connected in a rotationally fixed manner to a shaft on a ventilation side of the rotary machine and configured to generate a main cooling air flow when the shaft rotates about an axis. The fan includes a cover which is configured to direct the main cooling air flow onto the housing and is structured to improve cooling of the housing. An air guide element is detachably fixed to the cover to generate an additional cooling air flow. The air guide element, when viewed in a circumferential direction, has a segmented design and is configured as separate part for retrofitting to the cover depending on a thermal requirement of the rotary machine. --,

摘要： A conductor bar of a cage rotor of an asynchronous machine has a longitudinal extension and includes first and second sections in the longitudinal extension. The first section has a hardness which is lower than a hardness of the second section and is realized through soft annealing, brief inductive heating or heating by a flame so as to enable a compression of the first section of the conductor bar by way of axial pressure after axially joining the conductor bar in a slot of a magnetically conductive body of the cage rotor, with the first section abutting an inner wall of the slot of magnetically conductive body of the cage rotor.
