Abstract
PURPOSE: To make a rotor light-weighted and to eliminate an electrical noise from a commutator portion by together with installing a noise eliminating element material on a rotor of an iron core-less revolving electrical machinery, commonly using these element base plates as a coil holding plate of iron-less coils.
CONSTITUTION: A commutator structure 13 mounted concentrically on an output shaft 18 of a rotor of an iron core-less revolving electrical machinery and a circular disc shaped electrical noise eliminating element base plate 15 which is mounted on an output shaft 18 of its central portion contacting with riser portions 14 of the commutator structure 13, also mounted at one end portion of iron-less coils 19 of its outer peripheral portion and is commonly used to support coils 19 are provided. And noise eliminating elements 16 of plural numbers are installed annularly upon the base plate 15 and a connecting portion 22 between elements 16 and lead wires 20 of iron-less coils 19 are connected to risers 14 of a commutator structure 13 respectively. As it is constituted in this manner together with enabling a rotor structure to be light-weighted, an electrical noise from a commutator portion can be eliminated effectively.
