Book Optimization of multiphase permanent magnet synchronous machines on system level with reduced losses

Download or read book Optimization of multiphase permanent magnet synchronous machines on system level with reduced losses written by Dhamodaran. Nidhesh and published by BoD – Books on Demand. This book was released on 2022-01-01 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The requirements of an electrical machine (EM) in Electric- (EV) and Hybrid Electric Vehicles (HEV) are high power density, a stator and rotor field with low harmonic content and best acoustic behavior. Six-phase permanent magnet synchronous machines (PMSM) have significant benefits over conventional three-phase PMSMs, such as reduced current per inverter phase leg, less fundamental losses because of a better winding factor and increased fault tolerance. Despite their advantages, considering the same installation space, the torque per ampere increase of a six-phase PMSM is very marginal. Therefore, the main focus of this dissertation lies in increasing the power density of the multiphase electric drive, where optimizations and investigations are done on a system level. System level simulation models, which consist of the power electronics, different control strategies and the electrical machines are developed and studied. Considering the electrical and mechanical phase shift between the two three-phase winding sets, different winding concepts of the sixphase EM are developed, in an effort to gain a better understanding of their advantages and disadvantages. Detailed analyses are performed, in order to understand the sources and influences of the space harmonics and high frequency inverter-induced time harmonics on the losses and performance of the EM. In particular, this dissertation will examine the EM torque, iron losses, magnet losses and copper losses for both inverter switched currents and sinusoidal currents supply.

Book Third Harmonic Utilization in Permanent Magnet Machines

Download or read book Third Harmonic Utilization in Permanent Magnet Machines written by Kai Wang and published by Springer. This book was released on 2018-08-29 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the utilization of harmonics in the permanent magnet (PM) or rotor shape to improve the torque density of PM brushless AC machines including three-phase inner rotor and outer rotor machines, five-phase machines, dual three-phase machines, linear machines, by means of analytical, finite element analyses, and as well as experimental validation. The torque density can be improved while the torque ripple remains low in PM shaping utilizing the 3rd harmonic. In this book, the analytical expression of output torque is derived for PM machines with rotor shape using the 3rd harmonic, and then the optimal 3rd harmonic for maximizing torque is analytically obtained. The book compares the PM shape in surface-mounted PM (SPM) machines and the rotor lamination shape in interior PM (IPM) machines utilizing the 3rd harmonic, and it becomes clear that their shaping methods and amount of torque improvement are different. In a five-phase PM machine, the 3rd harmonic can be utilized in both the current waveform and PM shapes to further improve the output torque. For the dual three-phase SPM machines without deteriorating the torque more than 30% when the optimal 3rd harmonic into both the current and PM shape are injected. The harmonics in airgap flux density have significant influence on the cogging torque, stator iron flux distribution, and radial force between the rotor and stator. These effects has been investigated as well in this book.
