Permeance Based Algorithm For Computation Of Flux Linkage Characteristics Of Non-Linear 6/4 Switched Reluctance Motor (SRM)

The concept of permeance is used in the analysis of flux linkage of 6/4 SRM. The aim of this paper is to develop an efficient algorithm exploiting the nonlinear feature of the 6/4 SRM using the aforementioned concept of permeance. The first step is to generate the relevant equations related to permeances of the 6/4 SRM under study. The 6/4 SRM’s magnetization curve is then derived from the summation of mmf drops at various blocks representing the motor. The air gap permeances are derived at various angles and 3-D leakage effects are taken into account. These permeances are used for the mmf drop computation. The algorithm is capable of efficiently computing mmf drop at every block to consequently yield a complete accurate nonlinear flux linkage feature of the 6/4 switched reluctance motor. In this way, the capability of the SRM to produce the expected four times the specific output torque due to operation in high saturation region compared to an equivalent induction motor as special the attribute of the SRM is demonstrated

The Malaysian Millennials' Characteristics: an Investigation on Selected Public Universities

This paper aims to explore the characteristics of millennials as espoused in most literature. There are seven characteristics of millennials and each characteristic became the focus of the present study. As most literature on the millennials' characteristics is based on western context, this paper looks into the resemblance of the millennial characteristics' descriptions among the Malaysian public university students. Employing a survey, data for the study were collected using an adapted questionnaire. The respondents for the study were selected Malaysian millennials who were social sciences undergraduates in nine public universities. A cluster sampling method resulted in a total of 646 respondents who took part in the survey. It was discovered that the selected Malaysian millennials confirm some of the attributes in the seven characteristics of millennials
