41	Rotor-stator capsule construction	US3564314D	1969-07-11	US3564314A	1971-02-16	HAYDON ARTHUR W
A rotor-stator capsule for use with a field-winding to form an electric motor. The rotor of the capsule comprises a slender cylinder of permanently magnetized ferrite material, while the stator structure includes a pair of stator pole pieces at opposite ends of the rotor, each pole piece has a flat portion and two salient stator poles extending perpendicularly from the periphery of the flat portion in radially spaced relationship with the rotor. A tubular dust cover surrounding the rotor serves as a part of the shading assembly used to make the motor unidirectionally self-starting and this dust cover lies in the airgap between the rotor and the stator poles and extends axially along these poles for the length of the rotor. The shading assembly also is provided with a shading member which is interwoven with the stator poles and cooperates with the dust cover to complete the magnetic circuit.
