ABSTRACT:
Longitudinally extending radially-projecting and peripherally-spaced teeth on a stator member and rotor member of a synchronous electric motor, whose rotor member is magnetized by a permanent magnet, are skewed relative to each other. The overall peripheral distance of each tooth on one member is equal to or less than the space between the overall peripheral distances of the teeth on the other member. According to one embodiment the rotor teeth are skewed relative to the rotor axis and the stator teeth parallel thereto.
