摘要：
A rotary electric dynamo machine in which the ripple component in the output occurs at a higher frequency. One half of the pole faces have a nonuniform airgap while the other half have a uniform air gap and cover a noninteger slot distance. The armature has an odd number of slots. Instead of the usual ripple component at the slot frequency, a dynamo constructed as described above, surprisingly, has a predominant ripple component at twice the slot frequency.
