摘要：@ A permanent magnet motor includes stator means (52), rotor means (54) and electronic control means (56). Each stator means includes permanent magnets (90, 92)having pole faces (152, 154) that define a gap (102) between them with a generally
uniform magnetic flux density thereacross. Each gap (102) has an entrance section, an exit section and a generally curved longitudinal path extending from the entrance section to the exit section about the rotor axis (63). The magnetic flux density changes as one moves from the entrance section to the exit section as a function of arc degree position around the rotor axis. Each rotor means includes a predetermined number of permanent magnets (116) disposed radially outwardly from the rotor axis (63). These rotor magnets are disposed within the gap (102) and the magnet field of each rotor magnet interacts with the magnetic field of the associated stator magnets through repulsion or retraction. The electronic control means (56) induces an electromagnetic field that interacts with a magnetic field of a rotor magnet (116) or the stator magnets (90, 92) selectively to enhance or retard the rotational speed of the rotor (54).
