A comparison between conventional and flux‐intensifying interior permanent magnet synchronous machines

Abstract

Summary Flux intensifying interior permanent magnet synchronous machine (FI‐IPMSM) was designed to improve the characteristic of conventional permanent magnet machine, especially, in field weakening region. Increasing a saliency ratio is the main method to achieve this target which leads to increasing reluctance torque than magnetic torque and so improving the machine performance. In this paper, the characteristics of FI‐IPMSM are investigated. The effect of PM material, PM width, PM thickness, flux barriers width, and iron bridge thickness on the machine parameters is studied. Machine inductances, no‐load and full‐load characteristics are analyzed. A comparison is carried out between the FI‐IPMSM and conventional IPMSM to evaluate the improvement in machine performance. Two‐dimensional time‐steeping finite element method (FEM) is employed in analysis of the FI‐IPMSM and conventional IPMSM.

Analytical modelling of one cage rotor induction motor for electric submersible pumps

“…So far, different techniques have been used for electromagnetic modelling of CRIMs. The most famous technique is finite element method (FEM) [2,3]. However, FEM is a timeconsuming technique and it is better used in final stage to verify the analytical results [2].…”

A comparative dynamic analysis between model predictive torque control and field‐oriented torque control of IM drives for electric vehicles

“…The approach depends on FLC controller. A comparison was carried out between the FI‐IPMSM and conventional IPMSM in Reference 23 to evaluate the improvement in machine performance. A comparative study between FOC and MPTC applied to IMs was presented in Reference 24.…”
