Salient pole core and salient pole electronically commutated motor

摘要

An inside-out salient pole core for a dynamo-electric machine. The core has an edgewise wound yoke including an edgewise and helically wound strip of generally thin ferromagnetic material having at least one edge defining an outer circumferential surface on the edgewise wound yoke and extending generally axially thereacross. A set of salient pole pieces is secured to the edgewise wound core at least generally adjacent its outer circumferential surface, and extends generally outwardly from the outer circumferential surface about a set of preselected pitch axes, respectively.
