Squirrel-cage winding for electrical induction machine - has axially projecting cage bars subdivided at projecting end regions with associated ends bent away from each other

摘要

The winding includes a sheet metal package (1). Short circuit rings (2) axially spaced from the sheet metal package are connected to axially projecting cage bars (3), which are subdivided, at least at their front side, projecting and regions, to form separated bar ends lying one above the other. The bar ends associated with one groove are tangentially bent away from each other. ADVANTAGE - Torsional vibration stiffness is considerably increased.
