Title:
STATOR
Document Type and Number:
WIPO Patent Application WO/2014/184518
Kind Code:
A3
Abstract:
The invention relates to a stator module (21) for a multi-phase electrical machine. The stator module comprises a plurality of stator blades assembled together in an axial side-by-side arrangement and having an air gap between adjacent blades. Each stator blade comprises multiple coils (23, 25, 27) which may be embedded in a resin or encapsulation compound. One coil (23) in a stator blade is electrically connected to a corresponding coil (23') in an adjacent stator blade to provide one electrical phase. Stator modules (21) may be juxtaposed in the same plane to form a stator modular assembly (30). Each stator module is provided with an independent cooling system (50, Fig. 5). Advantageously, if a coil (23, 25, 27) or cooling system fails then a complete stator module (21) can be removed without affecting the operation of remaining stator modules within a multi-phase electrical machine.
