Position/speed Sensorless Control for Permanent-magnet Synchronous Machines

Design and Rotor Geometry Analysis of Permanent Magnet–assisted Synchronous Reluctance Machines Using Ferrite Magnet

Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...

Maximum Efficiency per Torque Control of Permanent-Magnet Synchronous Machines

Abstract: High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization. This paper proposes a novel analytic loss model of PMSM in either sine-wave pulse-width modulation (SPWM) or space vector pulse width modulati...

The Impact of the Selection of Permanent Magnets on the Design of Permanent Magnet Machines – a Case Study: Permanent Magnet Synchronous Machine Design with High Efficiency

Considering that the natural sources of the earth are limited, it is necessary to produce economical electrical machines with a high efficiency through better design and a proper selection of materials. At present, magnets have a high energy product (BHmax) with suitable magnetic and physical properties for applications in electrical machines. This paper considers how an electrical engineer cou...

The “Goodness” of Small Contemporary Permanent Magnet Electric Machines

The interest in adopting electric actuation in Navy ships, and in particular in submarines, usually founders on the issue of the mass and volume of electric actuators, which are perceived to be significantly worse than those of competing technologies. Certainly looking at the volume, mass, power and torque of a typical 3 phase induction machine, even in comparison with a typical automobile engi...
