直驱式风力发电机定子线圈结构型式的探索改进

Study on the Improvement of Stator Coil Structural Form of the Direct-driving Wind Power Generator

介绍直驱式风力发电机的发展状况,并简述其工作原理。在发电机定、转子直径尺寸不变的状况下,围绕着降低成本、提高效率以及提高系统可靠性这几个要点,探索定子铁心槽形和直驱式风力发电机定子绕组的结构型式。

The development of the direct-driving wind power generator was introduced while the operational principle of it was described. In the condition without any change of the diameter of stators and rotors and aimed round the cost cut, efficiency increase and system reliability improvement, the slot shape of the core and winding struc- ture of stator of the direct-driving wind power generator was studied.
