Title:
ROTARY ELECTRIC MOTOR HAVING AXIALLY ALIGNED STATOR POLES AND/OR ROTOR POLES
Document Type and Number:
WIPO Patent Application WO2003030333
Kind Code:
A3
Abstract:
A rotary electric motor comprises a rotor having a plurality of permanent magnet elements disposed in an annular ring configuration about an axis of rotation, the magnet elements successively alternating in magnetic polarity along an inner annular surface, and a stator spaced form the rotor by a radial air gap. The stator includes a plurality of magnetic core segments having respective coils wound thereon to form stator windings, the core segments separated from direct contact with each other and disposed along the radial air gap. Each stator segment comprises a pair of poles aligned with each other in a direction parallel to the axis of rotation. Thus the stator comprises a first set of stator poles in radial alignment and an axially displaced second set of stator poles in radial alignment.
