Compact windings design for traction induction motors and SCIGs

In this article winding schemes and calculation methods for original energy efficient electric machines are introduced. They are intended for application in electrical equipment of autonomous systems. These machines winding conductors have a rectangular cross-section. Slot connection spots and overhang parts are reduced. This allows one to reduce copper intensity and the machine length and improve efficiency. Specific end-face schemes and the conductors connection diagram for the stator windings are given. Overhang deviation and machine characteristics calculation features are described. The thermal simulation was undertaken for original conductors. The calculation results are compared with serial produced electric machines.
