Optimlzing system efficiency using premlum efficient motors

Industry Applications Society 60th Annual Petroleum and Chemical Industry Conference, 2013
Engineering, in its variety of disciplines, has always been to overcome challenges. The present overriding challenge is to maximize energy efficiency and reduce energy usage. A significant stage in accomplishing this challenge is the emphasis on the installation of premium efficient motors compliant with the National Electrical Manufacturers ...

High‐Efficiency Motors

Journal AWWA, 1987
The replacement of older models of pump motors with new, high‐efficiency motors can be an effective means of conserving both energy and capital. To promote this method of conservation, in 1983 the Pacific Gas and Electric Company (PG&E) initiated a rebate program to encourage its water utility customers to install high‐efficiency motors wherever ...

Premium efficiency motors effectiveness

SPEEDAM 2010, 2010
The paper presents an experimental comparison of the efficiency performances of 3 hp Premium efficiency induction motors issued from three different main manufacturers. In general, the obtained experimental results concord sensibly well with the rated nameplate data.

Induction Motor Efficiency

IEEE Industry Applications Magazine, 2011
A comparison of the direct and indirect measurements of induction machine efficiency from a collection of test data is presented in this article. The efficiency is computed from 1,000 induction motors rated 1-250 hp to show the relative accuracy of the methods. The Bland-Altman procedure for comparing measurement methods is used in the analysis.

Rectification efficiency of a Brownian motor

Physical Review E, 2003
The energy balance of a Brownian motor is discussed based on a Langevin equation without the overdamped approximation. Energetics of the system suggests that the frictional dissipation energy associated with the unidirectional movement should be counted as a part of the useful energy for the rectification process of a Brownian motor.
