摘要
在2 000 kW高速比直流电机电磁设计中,采用带均压线的单叠异槽式电枢绕组和分块电刷等,来提高电机的换向性能;绕组端部采用下压式无纬带结构,以满足电机的高速运行;电枢铁心采用径向通风,在转轴筋之间焊接倾斜导风板,以提高电枢通风冷却效果。
The single stack of different-slot armature winding with equalizing line and block brush was applied in the design of 2 000 kW motor with high speed-regulation ratio, to improve the commutation performance; the down- ward-pressure weftless tape was employed in the end winding structure, to fit with the high-speed operation; the radial ventilation was furnished in the armature shaft and inclined air guide plate was welded between the shafts to enhance the cooling and ventilating effectiveness of the armature.
