Modeling and simulation of a 3-ф induction motor based on two types of WFA

Abstract

This paper has been proposed to simulate the transient model of 3-Ф cage rotor induction motor based on winding function approach (WFA). According to this method the motor is assumed to be consist of an electrical circuits on both stator and rotor. The magneto motive forces (MMF) that have been generated by these circuits play a role for coupling them together. Then mutual and self-inductances will be easily computed using WFA. Two types of WFA have been used to build and simulate the model of the induction motor. In the one part type, it’s assumed that the coupling MMF between stator and rotor have a non-sinusoidal shapes according to the actual windings distribution over the motor slots. While in second part type the generated MMF in are assumed to have sinusoidal waveform. The suggested models may be used to simulate the dynamic as well as steady state performance of a faulty and non-faulty motor. A simulation of the suggested models that consists of m-rotor bars and n-stator phases multiple coupled circuit-based has been performed using matlab m.file and the results of the motor current have been proved in its nonlinear way by using WFA.

“…FFT is often applied to process digital signals or solve partial differential equations into algorithms for integer doubling [32]. The fundamental difference in DFT computational load is quite heavy because it requires several N2 complex multiplications, while FFT has a lighter computational load [33]. The FFT will divide the sampling results into several parts, which will then be solved using the same algorithm and collected back into one part.…”

“…Keunggulan motor ini antara lain memiliki konstruksi sederhana, harga murah, dan mudah didapatkan dipasaran. Namun disisi lain motor ini dalam pengendalian kecepatan putarnya tidak mudah [1], [2]. Ada dua cara pengendalian atau pengasutan motor induksi yaitu pengasutan secara langsung dan tak langsung.…”

“…Where (V a, V b, V c ) represent the three phase voltages of the balanced system, (V α, V β ) are the two-phase quadrating stationary balanced system. Based on Park transformation method the two-phase stationary system (V α , V β ) are transformed into two-phase rotating synchronous references frame as illustrate in Figure (2) and given by the ( 5), (6) [20], [23]. Where (v abcs , v abcr , ψ abcs, ψ abcr, i abcs, i abcr , R s , R r ) are the three phase voltages, linkage flux, current, phase resistance of the stator and rotor respectively.…”
