    Abstract: Permanent magnet motors having improved power output to size ratios, which include a casing of magnetically soft material, permanent magnets housed in the casing, an armature surrounded by the permanent magnets so dimensioned that the ratio of its diameter to the exterior casing diameter is substantially closer to the optimum than in heretofore available permanent magnet motors, and an arrangement for preventing demagnetization of the permanent magnets when the flux generated in the armature is greater than the flux which the permanent magnets can withstand without beginning to demagnetize.
