Electrical machine having a solid rotor and a cage winding

摘要

The bars (2) of the cage winding, which is located in a solid rotor (1), of an electrical machine are located in holes (3) in order to simplify manufacture. The cross-section of these holes (3) is larger than the bar cross-section, and the magnetic filling elements (4) fill the free cross-section of the hole (3). The bar (2) does not have a circular cross-section, and the filling elements (4) are arranged adjacent to the narrowest point (5) between the holes (3) in order to prevent magnetic bottlenecks. IMAGE
