“…The world of Permanent Magnet (PM) synchronous machines spans a very wide range of sizes and uses. Recent key electrification applications such as traction, green energy conversion, and more-electric aircraft make use of high-density PM machines of different types, including both salient-pole Interior PM (IPM) and Surface-mounted PM (SPM) machines that are designed to operate with high levels of magnetic saturation [1][2][3]. All such machines have a nonlinear magnetic model, intended as the relationship between the current vector and the flux linkage vector, normally represented in the dq frame synchronous to the rotor.…”

The Magnetic Model Self-Identification of PM Synchronous machines is proposed and experimentally validated. Provided that the shaft is free to turn, the commissioning procedure consists of spinning the machine to positive and negative speed values by way of an appropriate pattern of dq current reference values. The flux linkage versus current curves of the machine are constructed during the test via the standard measurements available on any industrial drive: phase currents, dc-link voltage and shaft position. Respect to the literature, the proposed method does not require a specific test rig nor off-line mathematical manipulation.

“…To avoid stator segmentation, plug-in teeth, use of SMC, or increased eddy losses in conductors due to open slots, a new manufacturing method for semiclosed slots for distributed windings is gaining ground for EV/HEV applications [3], [4]. In this paper, bar-wound copper conductor windings for semiclosed slots are fabricated using a special process described further in Section III-B.…”

The design of an in-wheel direct-drive motor for electric and hybrid electric two wheelers is studied, with particular focus on the use of bar-wound conductors in stator. In serving the space-constrained design problem of simultaneously achieving conflicting objectives of weight, cost, and short-term torque rating, this paper aims at comparing machines equipped with bar-wound stators with multistrand wound machines. This paper proposes different conductor shapes and arrangements that combine the advantages of fractional slot concentrated windings with bar conductors and describes the special fabrication method adopted for semiclosed slot geometry. The implications of using bar conductors on eddy effects and thermal equivalent circuit of the motor are studied and characterized experimentally. Finally, to investigate the impact of bar windings over multistranded windings on the ultimate performance metrics, a design study is conducted using a multiobjective optimizer for the two cases, and the resulting Pareto optimal sets are compared. The concept of the bar conductor tooth-wound motor is tested on a laboratory prototype, and the test results for skin effect, thermal contact resistance, and load tests are presented.

“…A máquina síncrona de ímã permanente (MSIP) no rotor é considerada uma atrativa topologia de máquina elétrica para o acionamento elétrico de ampla variedade de aplicações em também ampla faixa de potência. Elas são empregadas em escala de dezenas de Watts, como discos rígidos de computadores, bem como em escala de quilo e mega Watts em tração veicular, propulsão de embarcações ou aeronaves e geradores eólicos [1][2][3][4][5][6][7][8].…”

Para concretização do projeto de doutorado, máquinas elétricas foram construídas, peças mecânicas foram fabricadas, placas de circuito foram impressas, algoritmos foram simulados, códigos foram embarcados e, principalmente, ideias foram discutidas, compartilhadas e testadas. Em cada pequeno passo dessa tese pude contar com a contribuição de pessoas as quais sou muito grato.Primeiramente, meus sinceros agradecimentos ao meu orientador Dr. José Roberto Boffino de Almeida Monteiro por ter guiado meus estudos, pelo suporte técnico e pessoal e incentivo ao longo desses desafiadores anos de jornada no doutorado.
