Interior Permanent Magnet Synchronous Motors Mainly Using Reluctance Torque
IEEJ Transactions on Industry Applications, 1999 Permanent magnet synchronous motors (PMSMs) are widely used in many applications as high-performance variable-speed drives. In the traction drives such as an electric vehicle and the compressor drives of air conditioner, a wide constant-power speed range as well as a high efficiency operation are desired.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Estimation of Saturation of Permanent-Magnet Synchronous Motors Through an Energy-Based Model [PDF]
, 2011 We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, EarlyView.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.
