LabVIEWを用いたユニバーサルモータの整流子片とブラシの接触割合検討(電気工学科,工学部創設40周年記念号)

Abstract

The universal motor (single-phase AC series commutator motor) is widely used for home appliances such as vacuum cleaner, because of it's small size, light weight and high-speed rotation. We measure the armature terminal voltage of this motor during rotation and reported that the large and small pulse voltage of a repetition appears. We make it clear that the large and small pulse voltage of this armature terminal and the rate of contact of a segment and the brush under rotation become what relation. And in order to ask for the phenomenon that large and small pulse voltage has occurred, we produce the graphic model of a commutator and perform simulation analysis using LabVIEW(Laboratory Virtual Instrument Engineering Workbenc) software.
