In this paper, one of the main cogging torque minimization methods, magnet skew, is examined in detail for Axial Flux Permanent Magnet (AFPM) disc motor. Various magnet skewing methods, types, and effects on the machine performance are also investigated using 3D Finite Element Analysis. The results are compared with a reference AFPM motor, and the improvements on cogging torque component are de...

in this paper, the driver with antiwindup and fuzzy high-performance and robust pi controller has been suggested for permanent magnet synchronous motor (pmsm). this controller is suggested for the design of the robust driver for three phase pmsm and the cost reduction of its control system. it’s useful for the industrial application and automation and ultimately speed control and the improvemen...

To analyze responses under open fault conditions in switching devices, a performance investigation and condition monitoring scheme are presented through an integrated simulation study of a permanent magnet synchronous generator (PMSG) based variablespeed grid-connected wind power system. Among various faults in power electronics components, the open fault in switching devices may arise due to t...

SIMULATION OF POWER CONTROL OF A WIND TURBINE PERMANENT MAGNET SYNCHRONOUS GENERATOR SYSTEM Nantao Huang, B.S. Marquette University, 2013 This thesis presents a control system for a 2MW direct-drive permanent magnet synchronous generator wind turbine system with the objectives to capture the optimal power from the wind and ensure a maximum efficiency for this system. Moreover, in order to elimi...

This paper proposes a method of applying the Space Vector Modulation technique for Direct Torque Control (DTC) of a permanent magnet synchronous motor (PMSM) drive. By this method it is preserved the principle of the conventional DTC regarding the decoupled torque and flux control, while providing more flexibility for the inverter voltage utilization, in order to compensate the torque and flux ...
