This paper aims to prcsult investigation result3 related to inducton motors operation unda non ideal supply conditions. The motors are of squirrel cage type andthc non ideal cmditions are assaciated to harmonics, uubahces, voltage sag and swell, etc. a studies are carried Out using time domainmodeling and the SABER simulator. using this wmputatid result3 are derived in order to mpam the non ideal m o t o r p e r 6~ to the ideal ones 90 that the real supply umditiim effect upon the motor behaviorcanbehigblightcd In addition to te4Anical aspects, the powerquality impactonenergyandfinanciat wasteand isalso ddered.
Having the property to modify only the geometry of a polygonal structure, preserving its physical magnitudes, the Conformal Mapping is an exceptional tool to solve electromagnetism problems with known boundary conditions. This work aims to introduce a new developed mathematical operator, based on polynomial extrapolation. This operator has the capacity to accelerate an optimization method applied in conformal mappings, to determinate the equipotential lines, the field lines, the capacitance, and the permeance of some polygonal geometry electrical devices with an inner dielectric of permittivityε. The results obtained in this work are compared with other simulations performed by the software of finite elements method, Flux2D.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
