Hybrid permanent-magnet synchronous motor.
IEEJ Transactions on Industry Applications, 1990 A number of configurations for interior permanent-magnet type synchronous motors have been developed in recent years. This paper describes a form of motor having large output and high efficiency. Use can be made of samarium cobalt magnets, and the volume of the magnets used in the rotor is small compared with that of the conventional permanent-magnet ...

Advanced Materials, EarlyView.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Research on an Improved Method for Permanent Magnet Synchronous Motor [PDF]
Journal of Sensors, 2014 In permanent magnet synchronous motor (PMSM) traditional vector control system, PI regulator is used in the speed loop, but it has some defects. An improved method of PMSM vector control is proposed in the paper. The active-disturbance rejection control (ADRC) speed regulator is designed with the input signals of given speed and real speed and the ...
