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 | | 出版日期 | Book 2019 | | 关键词 | Permanent magnet machines; Third harmonic; Torque density; PM shaping; Harmonic current injection; Torque | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-13-0629-7 | | isbn_softcover | 978-981-13-4465-7 | | isbn_ebook | 978-981-13-0629-7 | | copyright | Springer Nature Singapore Pte Ltd. 2019 |
