   Control and Integration of a multiphase Brushless Wounded Synchronous Motor Drive
By Rémi PERRIN [View]
[Download]

Abstract: This paper presents a fully integrated seven-phase Brushless Wounded Rotor Synchronous Motor BWRSM machine drive and its control. A direct integration strategy of the power electronics on the motor case is performed. Advanced PCB integration with embedded die are used for low profile rotary transformer. For the control side, the machine was modelled by Finite Element Method (FEM) in order to extract the flux tables. These tables were then used to improve the precision of analytic simulation model. By using so obtained analytic simulation with integrated flux tables designed field-oriented control was verified. Details on design and the model are presented in the paper. Finally, the controller's efficiency and the power electronics of the motor drive are confirmed with experiments on described prototype machine.

   Inductance Analysis of Electric Machines by Classical and Numerical Methods
By Tim MILLER [View]

Abstract: In electric machine design calculations, strong compatibility is essential between the methods used todesign windings, the equivalent circuit model, and the overall electromagnetic performance. This paper presents a structured classification of complementary methods to achieve a unified approach, withparticular focus on inductance calculations using classical and finite-element methods.

   Performance Evaluation of Sinusoidal-Flux Reluctance Machine for Improving Power Density with Reduced Torque and Input-Current Ripples
By Kiwa NAGAYASU [View]
[Download]

Abstract: Reluctance machines are attractive for vehicle propulsion for being free from the permanent magnets, although conventional reluctance machines, such as the synchronous reluctance machine (SynRM) and the switched reluctance machine (SRM), suffer from low power density or large input-current and torque ripples. To solve these problems, a recent study has proposed the sinusoidal-flux reluctance machine, which is operated with the sinusoidal phase flux waveform. This preceding study has confirmed the operating principle of this machine, although little information has been provided on the performance compared to the existing reluctance machines. The purpose of this study is to elucidate the benefits of the sinusoidal-flux reluctance machine compared to SynRM and SRM. This study experimentally tested the performance of the sinusoidal-flux reluctance machine, SynRM, and SRM, designed under the conditions of the same stator core and the same rotor outer diameter. The experiment revealed that the sinusoidal-flux reluctance machine can reduce the peak flux compared to the SynRM with smaller toque and input-current ripples than the SRM, suggesting that the sinusoidal-flux reluctance machine is promising for vehicle propulsion.
