BROTHERS WITH NEW BROTHERS

摘要

A multi-pole, multi-speed brush holder assembly is created by joining a first speed brush holder assembly and a second speed brush holder assembly together, back-to-back, with an apertured spacer sandwiched between them. A plurality of brush holders are disposed on the cards' front faces and spaced circumferentially around a central aperture of the respective card. Brushes are guided by the brush holders and spring-biased toward the respective aperture for engaging a respective commutator of a motor armature. On each card, a respective first electric conductor segment is disposed flat against the card's back face and electrically connects the brush of a first of the card's brush holders with the brush of a second of the card's brush holders. On each card, a respective second electric conductor segment is disposed flat against the card's back face to electrically connect the brush of a respective third of the card's brush holders with the brush of a respective fourth of the card's brush holders. The first conductor segment of one card is spaced radially outwardly of the second conductor segment on the same card; on the other card, it is spaced radially inwardly. The first conductor segments are on a common radius and in mutual abutment to provide continuity of the first and second brush holders on one card with the first and second brush holders on the other card. The spacer's thickness is no greater than the sum of the thicknesses of the first conductor segments on the two cards.
