Tendencies in development of wind power industry including direct-drive small-scale wind power plants and generators have been analyzed. Synchronous generators with permanent magnet excitation for direct-drive wind power turbines are described. Primary magnetic field distribution and effect of armature reaction have been studied for design of a low-speed multipole permanent-magnet synchronous g...
Sensorless position control of Surface Mounted Permanent Magnet Synchronous Machines (SMPMSM) still is a challenge. High performance position control at low and zero speed is only possible using anisotropic effects being not considered in the fundamental-frequency machine models but in extended highfrequency models. This paper presents a new highfrequency injection method estimating the rotor p...
in order to solve the problem of robustness or antidisturbance of the traditional PI speed controller in the permanent magnet synchronous motor. A fuzzy PI speed controller based on load torque feedback compensation is proposed for the permanent magnet synchronous motor. The combination of fuzzy PI control strategy and load feedback compensation method can enhance the robustness and disturbance...
Permanent-magnet synchronous machines (PMSMs) are widely used in electric vehicles owing to many advantages, such as high power density, high efficiency, etc. Iron losses can account for a significant component of the total loss in permanent-magnet (PM) machines. Consequently, these losses should be carefully considered during the PMSM design. In this paper, an analytical calculation method has...
