Modern analysis techniques for electrical machines are either analytical or use finite element analysis. Both methods are implemented using computational techniques to solve the magnetic circuit and produce performance predictions. This paper puts forward a steady-state impedance matrix method for analysing a split-phase induction machine that is at the leading edge of analytical modelling of i...

A substantial amount of power system load is made of large number of three phase induction machine. The transient phenomena of these machines play an important role in the behavior of the overall system. Thus, modeling of induction machine is an integral part of some power system transient studies. The analysis takes a detailed form only when its modeling becomes perfect to a greater accuracy. ...

A fault diagnosis system based on pattern recognition techniques is developed for cage induction machine broken bar detection. The developed algorithm uses the stator current and, if available, motor speed as input data. Several features are extracted from the Frequency spectrum of the current signal derived using the Fast Fourier Transform. The relevance of the features for the purpose of faul...

This paper presents an easy to understand dynamic simulation model of Induction Machine Model on Simulink/MATLAB software platform. A somewhat different induction machine model equations in which flux linkage equations are expressed in terms of reactances rather than inductances is used. Also, the model equations for the three phase carrier-based pulsewidth voltage source inverter for driving t...

In this paper, a comparison between a classic direct torque control (DTC) and a modified (DTC) of a dual three phase induction machine (SPIM) will be introduced. In this work, the SPIM has a dual three phase windings spatially shifted by θ electrical degree wich is equal to 60◦. SPIM drive has 64 inverter switching states which provide higher possibility in selecting space voltage vectors than ...

Multiphase induction machine; Rectangular air–gap flux; Third harmonic injection; Eleven-phase Abstract This paper presents a modified V/f control strategy using neural network with an improved flux pattern using third harmonic injection for multiphase induction machines. The control objective is to generate a nearly rectangular air–gap flux, resulting in an improved machine power density for t...
