This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...

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...

axial flux permanent magnet (afpm) machines are attractive candidates for electric vehicles (evs) applications due to their axial compact structure, high efficiency, high power and torque density. this paper presents general design characteristics of afpm machines. moreover, torque density of the machine which is selected as main objective function, is enhanced by using genetic algorithm (ga) a...

In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...
