网上看到两则去年的新闻,也许有搞电机的感兴趣:

美国海军发合同给UQM公司,研制将永磁和感应式技术结合在一起的电机,以获得高转距体积比,高效率的电机。
Advanced motors will merge PM and reluctance technologies
The US motor manufacturer UQM Technologies has received a $100,000 contract from the US Navy to develop an advanced variable-speed electric motor design with a substantially higher torque density, power density and efficiency than currently available machines.
"This project will explore the potential of an innovative motor design that combines the torque production of both permanent magnet and reluctance motor technologies," explains Jon Lutz, UQM Technologies’ vice-president of technology. "Through a novel motor geometry, we hope to maximise both the torque and speed output of the motor and expand the output speed range beyond that of our currently available industry-leading technology."

Korean superconducting motor starts spinning
Two South Korean organisations – Doosan Heavy Industries and the Korean Electrotechnology Research Institute – have built and demonstrated a compact, high-efficiency superconducting motor for civilian and military applications. A government-backed development programme which started in 2004 has culminated in the 970kW demonstration motor, capable of spinning at 3,600 rpm. Doosan plans to offer commercial superconducting motors by 2010-2011.
The Korean super-motor contains 5km of superconducting wire supplied by American Superconductor (AMSC), which has recently completed factory acceptance tests on its own 36.5MW high-temperature superconductor motor which it is developing for the US Navy.
