ABSTRACT:
A rotor for small motors, or generators, having circumferentially arranged segmental poles which extend over the entire axial length of the rotor can be fabricated by molding a pair of elements from particulate magnetic material of high coercivity with a binder in the shape of identical crown gears; the rotor being completed by arranging the elements on a shaft with the toothed portions facing each other in interfitting engagement. Other modifications are disclosed in which the pole pieces may be formed separately from, or integrally with, a radial pole carrier, and the pole carrier may be in the shape of a spool with the segmental pole pieces assembled thereon.
