Analysis of the Body Sound of an
Induction Machine with Squirrel-Cage Rotor depending on the Coupling of
Stator and Housing (Masterarbeit)
Electrical machines, especially induction machines, produce unwanted
vibrations. These strongly depend on the machine's geometry and mechanic
structure. A main aspect is the coupling of stator and housing. The regarded
induction machine with squirrel-cage rotor is used as power-steering drive in
automobiles. FEM-models of different coupling concepts are simulated and the
body sound is analyzed. At first a cylindrical refernce
model is considered which is then modified. In this study the exsisting analytical models should be verified and the
impact of the coupling of stator and housing on the machine's vibrations
should be analyzed.
