PERMANENT MAGNET D.C. MOTOR HAVING A RADIALLY-DISPOSED WORKING FLUX GAP

摘要

A permanent magnet D.C. motor (90) includes a stator assembly (112) with a plurality of upstanding discrete spaced-apart core components (116) formed in a circular locus generally parallel with the motor axis. Each core component includes a relatively lengthy winding association region and extending therefrom a pole piece region (128) providing a flux interaction surface. A field winding (122) mounted upon a bobbin is positioned over a core component at the winding association region. A permanent magnet component (130) is carried by a rotor (100) such that its interaction surface is adjacent to that at the pole piece region (128), and is spaced therefrom to define a flux working air gap (132).
