Induction Machine Performance Improvements: Design-Oriented Approaches

Abstract

136 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2007.Finally, an induction machine model featuring a variable permeance element mesh is introduced. Results for a 500 W motor are compared to measurements, analytical models, and FEA. This machine has limited nominal torque capabilities due to saturated stator and rotor teeth, discovered neither by the design software (analytically based) nor FEA. The 3-D MEC model, about a magnitude smaller in complexity and size than the FEA model, more accurately estimates the limited torque. All the results indicate that MEC, corrected for local saturation, is a promising option for a design tool.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
