Multi objective design of high efficiency induction motor using an analytical method's

Abstract

In the final decade of the last century, there was enormous intellectual and engineering activity surrounding the recently invented induction motor, especially their efficiency increasing. The interest in improving the efficiency of electric motors stems from the fact that they represent 60 to 70% of the total industrial and commercial load. A knowledge the motors operating efficiency in an industrial plant is necessary, when deciding whether standard motors should be advantageously replaced with more efficient motors. A new approach is presented for analysis and design of closed rotor slot induction motors in this paper. The main idea is illustrated as follows: first based the computed machine parameters and motor geometry optimization will be carried out. Then, to validate the conceived machines, dynamical performance analysis will be achieved by MATLAB environment. Finally using finite element electromagnetic field analysis, the comparison results will be discussed and commented.

Reliability Comparison Between Standard and High Efficiency Induction Motor Using Vector Control Method

“…The result of this investigation is listed in Table 1. Further the machine performances can be deduced and also confirmed [2].…”

“…In general the method does not change since we always notice the same path that allows stator sizing followed a rotor calculation, terminate with electrical equivalent circuit Parameters [2].…”

“…First a view of social cognition, each individual in PSO can benefit from both its own experience and group findings. In its theoretical base, some factors are included [2,3]:…”

“…These machines cover the essential transforming electrical energy into mechanical energy. It is usually estimated that induction motors account for 70% of the installed capacity and 40 to 50% of the total energy consumed [1,2].…”

“…In addition, some of its state variables are inaccessible to direct measurements (rotor flux) [1,2].…”
