| Abstract: | This paper introduces the design and structural characteristic of Z2800/1240 3800kW large-sized DC motor. The motor is class F insulated. The main pole core,commutating pole core and armature all adopt vacuum press full impregnation（VPI） with solventless varnish. The armature conductors are of variable-cross-section,the armature bracket composes of three-layer star wheel disks and box-like arms,the stator frame is of upper and lower split structure,and the commutating pole windings are of foursquare welding structure. |
