Claridge Committee Members, Charles Culp Michael Pate Head of Department, Dennis O'Neal May 2010 Major Subject: Mechanical Engineering iii ABSTRACT Methods for Rapid Estimation of Motor Input Power in HVAC Assessments. (May 2010) Kevin David Christman, B.S.E., Walla Walla University Chair of Advisory Committee: Dr. David E. Claridge In preliminary building energy assessments, it is often desired to estimate a motor's input power. Motor power estimates in this context should be rapid, safe, and noninvasive. Existing methods for motor input power estimation, such as direct measurement (wattmeter), Current Method, and Slip Method were evaluated. If installed equipment displays input power or average current, then using such readings are preferred. If installed equipment does not display input power or current, the application of wattmeters or current clamps is too time-consuming and invasive for the preliminary energy audit. In that case, if a shaft speed measurement is readily available, then the Slip Method is a satisfactory method for estimating motor input power. -

Lci's and Synchronous Motors Applied to Roller Mills
LCI'S AND SYNCHRONOUS MOTORS APPLIED TO ROLLER MILLS For Presentation at the IEEEIPCA Cement Industry Technical Conference Salt Lake City, UT May 2000 By: James F. Zayechek G E Industrial Systems 1. Abstract A cement company concerned about high power-factor penalty costs requested an evaluation of the feasibility of using synchronous motors starting through LCl's to drive three new roller mills at a cement plant. The prior experience with roller mills centered about the application of wound rotor induction motors with either cascaded secondary resistance or liquid rheostat. By utilizing synchronous motors, there was the possibility of providing leading power factor to reduce the reactive power demands seen by the utility feeding the cement plant. It was theorized that, if sufficient power factor correction could be obtained, the payback period of the incremental additional cost of the synchronous motor drive system would be very short. After payback of the initial investment, all future energy savings gravitate directly to the bottom line as additional revenue. Several key concerns had to be addressed in evaluating the use of synchronous motors for these relatively high starting torque requirement applications. This paper discusses the electrical and mechanical evaluation leading up to the decision to proceed with this new application of synchronous motors started through an LCI. 2. Introduction Roller mills, also known as vertical mills, are becoming more prevalent in modern cement plants. These mills have application both for raw material preparation and clinker grinding to final specifications. The increasingly competitive nature of today's business environment is pushing the mill OEM's to larger mills with greater throughput. -

Dynamic Suspension Modeling of an Eddy-Current Device: an Application to Maglev
DYNAMIC SUSPENSION MODELING OF AN EDDY-CURRENT DEVICE: AN APPLICATION TO MAGLEV by Nirmal Paudel A dissertation submitted to the faculty of The University of North Carolina at Charlotte in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Electrical Engineering Charlotte 2012 Approved by: Dr. Jonathan Z. Bird Dr. Yogendra P. Kakad Dr. Robert W. Cox Dr. Scott D. Kelly ii c 2012 Nirmal Paudel ALL RIGHTS RESERVED iii ABSTRACT NIRMAL PAUDEL. Dynamic suspension modeling of an eddy-current device: an application to Maglev. (Under the direction of DR. JONATHAN Z. BIRD) When a magnetic source is simultaneously oscillated and translationally moved above a linear conductive passive guideway such as aluminum, eddy-currents are in- duced that give rise to a time-varying opposing field in the air-gap. This time-varying opposing field interacts with the source field, creating simultaneously suspension, propulsion or braking and lateral forces that are required for a Maglev system. In this thesis, a two-dimensional (2-D) analytic based steady-state eddy-current model has been derived for the case when an arbitrary magnetic source is oscillated and moved in two directions above a conductive guideway using a spatial Fourier transform technique. The problem is formulated using both the magnetic vector potential, A, and scalar potential, φ. Using this novel A-φ approach the magnetic source needs to be incorporated only into the boundary conditions of the guideway and only the magnitude of the source field along the guideway surface is required in order to compute the forces and power loss. -
