Our analysis also leads naturally to a modification of the LSC preconditioner that emphasizes important relationships for components of the commutator associated with boundaries.
The 140-channel commutator ring "is a pretty big leap from anything we've done on this size," the engineer said.
The elimination of the commutator tangs, especially in a face-type commutator, produces a very streamlined package that improves motor performance and efficiency.
As thermally insulated surfaces we accepted: lateral surfaces of commutator segments, contacting with insulating pads; surfaces of a front pressure-exerting cone and a commutator lug, insulated from armature winding.
Among the bright spots in the first quarter have been sales of PORON(R) materials to the printing industry, ENDUR(R) components for use in office equipment, and phenolic molding materials for automotive metal replacement and electric motor commutator applications.
