The invention relates to a squirrel-cage rotor of an asynchronous machine (), comprising conductors () in grooves () of a magnetic field-conducting rotor, and electrically conducting rotor end rings () which are located in the region of the end faces of the magnetic field-conducting rotor, electrically connect the conductors () and have at least two materials that conduct electricity differently.

Hybrid squirrel-cage rotor

The invention relates to an electrical machine () comprising a rotor () which is rotatably mounted around a rotation axis () extending in the axial direction () in bearing devices (), a stator () having two axial ends, an air gap between rotor and stator, an interior chamber () encompassing the stator () and rotor (), a sleeve () encompassing a first part () which encloses the interior chamber (), a frame () having a first () and a second () longitudinal support (), a first () and a second () cross-support, and a dividing device () on the frame (). The stator () comprises a fastening device () for connection to the frame () and the dividing device () can make the interior chamber accessible from the outside in a plane parallel to the frame (). The invention further relates to a collection, to a frame (), to a sleeve (), or to a service or production method of such an electrical machine ().

Electrical machine having a frame and sleeve

Electric motor

A stator for a rotating electric machine includes a laminate stack having a plurality of slots open towards an air gap between the stator and a rotor of the electric machine. A winding includes coils which have turns that pass through the slots of the laminate stack. The turns of the coils are electrically insulated the within the slots from each other and from the laminate stack by a ceramic material.

Stator of an electric machine and production thereof

A rotor of an asynchronous machine with a cage rotor includes a laminated core formed from a plurality of partial laminated cores. The laminated core has substantially axially extending conductors arranged in slots in the laminated core. The conductors include at least two materials of different electrical conductivities, such that a material with a higher electrical conductivity surrounds a material with a lower electrical conductivity by at least 65% in a circumferential direction.
