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

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

An interface (SSE) is provided for transmission of message cells appearing on an offering trunk (ZL) with a specific transmission bit rate and belonging to different virtual connections or virtual paths via inputs of an ATM communication equipment (ATM-K) designed for a lower transmission bit rate. This interface includes a plurality of processors (MBHE, SBHE1, . . . , SBHE3) connected to the offering trunk which have their output sides respectively connected to at least one of the inputs. Under the control of one of the processors as a master processor (MBHE), the message cells are cyclically distributed onto all processors and, subsequently, are forwarded by these processors to the ATM communication equipment, upon attachment of a sequence number that is valid at the moment for the respective virtual connection or respective virtual path.

Method and apparatus for transmitting message cells via an ATM

Multiplier circuit

A CMOS-ECL converter contains a drive stage modified from the prior art and a connected output transistor. The driver stage comprises a resistor element and an n-channel field effect transistor. The resistor element can preferably be constructed with the assistance of a p-channel field effect transistor and is connected in series with the n-channel field effect transistor. The advantage of such an arrangement is that the capacitive load at the input of the CMOS-ECL converter is low because the resistor element or, respectively, the p-channel field effect transistor, offers no contribution to such an input load. The channel width of the p-channel field effect transistor can be set such that an adequately-high base current for the bipolar output transistor can be supplied.
