During the design of permanent magnet synchronous machines (PMSM), the first step that engineers have to do, concern the choice of the topology, i.e. the slot/pole combination. Given that the performances of the machines are strongly related to this combination, the choice has to be fully justified. Fractional slots (FS)-PMSM offers several advantages and have been focused by a lot of researches. However, depending on the topology, these machines could have major drawbacks as magnetic noises, high iron and eddy-current losses and low fault-tolerance. The aim of this paper is to give an overview of each machine considering the most common slot/pole combination in order to single out if a topology is suitable or not. A special focus is also done on the homopolar component which traduces the machine's fault tolerant capability required for embedded applications.

Comparison of Inverter Topologies Suited for Integrated Modular Motor Drive Applications Ugur, Mesut; Sarac, Hakan; Keysan, Ozan (2018-08-30) In this paper, various inverter topologies are compared for integrated modular motor drive (IMMD) applications. Two-level voltage source inverter (2L-VSI), three level voltage source inverter (3L-VSI) and series/parallel combinations of these topologies with system level modularity are compared in terms of voltage and current harmonic spectrum, passive component sizes and motor drive efficiency. New generation wide band-gap GaN power semiconductor devices are utilized in modular topologies and they are comp...
Design of a GaN Based Integrated Modular Motor Drive Uğur, Mesut; Keysan, Ozan (2018-10-25) In this study, design procedure of an Integrated Modular Motor Drive (IMMD) is presented focusing on high power density. The design is based on a permanent magnet synchronous motor (PMSM) and GaN FETs. Fractional slot concentrated windings are used on the stator. Slot/pole combination and winding configuration is selected based on having low cogging torque and high winding factor. An extended motor drive inverter topology is proposed where 2-level voltage source inverters are connected both in series and pa...
Calculation of parameters of single-phase PM motor for design optimization Ertan, Hulusi Bülent; Capolino, GA (2005-09-01) This paper presents methods of calculation of parameters of single-phase permanent-magnet (SPPM) motor, in terms of motor dimensions and material properties, which are utilized in the dynamic model of the motor. The intention of the study is to develop means of SPPM performance calculations, which lend themselves to be employed within a mathematical design optimization approach. The calculated parameters are compared with measured values and are shown to be accurate for the purpose of the study.
Design and Testing of a Linear Generator for Wave-Energy Applications Hodgins, Neil; Keysan, Ozan; McDonald, Alasdair S.; Mueller, Markus A. (2012-05-01) A linear-generator topology is proposed for wave-energy applications. The main significance of the generator topology is that the relative position of the magnets, copper, and steels has been chosen so that there are no magnetic attraction forces between a stator and a permanent-magnet (PM) translator. The lack of magnetic forces and the modular nature of the generator topology make the manufacture and assembly of the generator easier than a conventional iron-cored PM linear generator. Analytical modeling t...
