Abstract

Machines with modular structure significantly simplify the manufacturing process, particularly the stator winding, and highly increase the slot fill factor. The non-overlapping concentrated winding, or single tooth winding, is the most compatible winding layout with segmented structure. This technology is well-established for permanent magnet family machines. However, their incompetence to produce a sinusoidal MMF distribution provides a key challenge to apply single tooth winding to induction machines. This paper introduces a new single tooth winding layout for a single-phase induction motor with segmented stator. The proposed winding layout is based on dual two-phase windings shifted in space by 450 electrical degrees to completely cancel out both the third and fifth order harmonics. The proposed winding entails 8 slots per pole pair. Although the number of active conductors in the proposed winding is higher than a conventional distributed winding layout to produce the same MMF magnitude, the significant reduction in the end turn copper and the increase in the slot fill factor compensate this copper volume increase while maintain approximately the same machine volume, which introduces it as a promising candidate in high frequency motor applications. A prototype machine is used for experimental verification.
