Title:
AXIAL-FLUX, PERMANENT MAGNET ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO2005119886
Kind Code:
A3
Abstract:
An axial flux, permanent magnet electrical machine is disclosed. The machine has at least one stator disc (12) and at least one rotor disc (10) co-axial with the stator disc and mounted for rotation relative to the stator disc. The rotor has a plurality of permanent magnets (18) mounted circumferentially thereon, and the stator comprises a plurality of discrete windings (24). The windings are recessed in the stator. The stator disc can be formed from a plastics material, and the rotor can have a segmented construction. The windings can also be arranged in groups to provide for a multi-phase machine.
