New Technique for Welding the Stator Spring Plates of Advanced 600 MW Turbogenerator 优化600MW汽轮发电机定子弹簧板焊接新工艺
The new technique for welding stator spring plates of advanced 600 MW turbogenerator is presented in this paper, and materials for the spring plates are introduced also. 论述了优化600MW汽轮发电机定子弹簧板焊接新工艺方法,并对弹簧板材料进行了介绍。
A new thin-type ultrasonic motor is designed, the rotor is installed inside ring stator to reduce the thickness of the motor and double piezoelectric plates structure is adopted in the stator to avoid exciting nonaxisymmetric-mode. 设计并制作了一种新的薄型超声电机。电机转子安装在圆环定子内,能够显著减小电机厚度,电机定子采用双压电片结构,可以避免激发出定子的非轴称模态。
