Abstract: Numerical models are developed to predict the electromagnetic vibration and noise of permanent-magnet direct current (PMDC) commutator motors when both rotor eccentricities and glue effects ...

The long-stalled West Hotel project on a prime corner of Minneapolis’ North Loop neighborhood has a new owner after its developers failed to secure the financing needed to complete construction. An ...

The Commutator/West Hotel project on Second Avenue in Minneapolis’ North Loop has been sitting, unfinished and seemingly untouched, for over two years now. Its complex of historic buildings is wrapped ...

RECENT advances in the application of single-phase alternating currents to electric traction have given rise to a large volume of literature dealing chiefly with the motors employed. The possibility ...

Abstract: The paper discusses the operating characteristics of large commutators. It is pointed out that many cases of blackened and burned bars are caused initially by a slight roughness which causes ...
