Prototype based study of different winding configurations with SM2C core

This paper summarises the outcome of an experimental study, which is related to a winding arrangement in a stator core that is made of Soft Magnetic Mouldable Composite - SM²C. The comparison is made between a distributed concentrated winding and a modular wave-winding, where the modular wave-coils are distributed either axially or circumferentially. Manufacturability and high winding fill factor are vital for a low permeability stator core in order to gain a good machine performance and a low cost in combination with moulding technique. A number of stators are built and verified in order to learn the theoretical and practical issues related to wave-windings.
