Analytical loss calculation tool for an induction motor

Abstract

This thesis introduces an analytical loss calculation tool which is able to predicate the loss components and efficiency of a specific 5 kW induction motor powered by a converter. The calculation tool functions in different operation modes in where voltage, frequency, torque and temperature are variables. The way the tool constitutes is illustrated with equations and relative descriptions. At the end of this thesis, analytical results gained by the already mentioned tool were weighted with real measured results given by LUT laboratory. The comparison proves the competence of this decent tool for estimating the loss components, predicating the efficiency and other extra information such as maximum torque, power factor, and impedance in rotor and stator.
