Designs and Drive Control of Electromechanical Machines

Dear Colleagues,

Electrical machines, which can be configured with different power ratings while maintaining superiorities of high efficiency and high power density, have been widely employed in various industry sectors, such as high-speed trains, industrial robots, wind power generation, and electric vehicles. For traction control systems, advanced solutions such as less rare-earth and rare-earth free machines, permanent magnet synchronous reluctance machines, in-wheel machines, and multi-phase/multi-three-phase machines have been widely investigated by both academia and industry. For high-accuracy-demanded drive systems, advanced solutions such as voice coil machines, linear machines, and ultra-high-speed spindle motors have been developed prosperously. As a result, numerous new materials, manufacturing and processing technologies, advanced topologies, and optimization techniques for electrical machines have been developed in recent years.

Meanwhile, as key equipment for electromechanical energy conversion, electrical machines also need corresponding drive and control schemes to guarantee their dynamic and steady-state performances. Therefore, a great number of advanced drive control schemes have been proposed in recent years for meeting the advanced control demands of electrical machines, such as lower switching losses, better fault tolerance and real-time condition monitoring, fewer sensors, parameter identification, and real-time observation.

To collect the latest developments in electrical machines and drives, we are pleased to invite the research community to submit review or regular research papers on, but not limited to, the following relevant topics:
