The permanent magnet synchronous machine with an external rotor is the most important device for high performance electrical drive systems in particular for hybrid electric vehicles. With such an application, the machine will operate in a wide speed range and on the other hand with very fast changing loads in both motor and generator operational modes. The paper discusses finite element analyse...

In this paper, a parameterized transient finite element model for permanent magnet (PM) dimension analysis and performance simulation of a V-shape interior permanent magnet synchronous motor (IPMSM) with 8 poles is developed. The relationships between induced electromotive force (EMF) and PM dimension, cogging torque and PM dimension are analyzed; the geometries of PM structure are optimized by...

This paper investigates the design of a robust linear parameter-varying (LPV) controller for speed regulation surface permanent magnet synchronous motors (SPMSMs). Motor dynamics is defined in t...
