LOSSES IN MACHINES
DOE grant to develop more efficient motors for residential and commercial building. [News Release]
List of Companies Advanced DC Motors Inc. [..] Black & Decker (U.S) Inc. [..] Eaton Corp. [..] Globe Motors [..] Lamination Specialities Corp. [..] Magnetic Instrumentation Inc./KJS [..] Magsoft Corp. [..] Proto Laminations Inc. [..] SMMA [..]
Goals Understand the scientific principles governing core losses in laminations. (Particularly as it relates to high frequency and non-sinusoidal excitation.) Develop an instrument capable of accurately measuring the core losses of motor laminations exposed to non-sinusoidal and/or high frequency excitations. Measure core losses of laminations when exposed to high frequency sinusoidal and non-sinusoidal waveforms. Develop design formulae for categorizing core losses as a function of frequency, lamination thickness, resistivity, peak flux density and wave shape. Encapsulate the important findings and results in a final report. Apply these design formulae to several prototype and the measure the improvements in efficiency.
