ABSTRACT:
The armature of an electric motor driven pump has a casing comprising a first end cap covering the end turns at one end of the armature core with a plurality of integral axially extending fingers disposed respectively in slots within the core, the fingers having means wedging them in the slots to prevent radial outward movement and a hook on the end of each having a ramp surface sloping radially inward from the end of the finger. The casing further comprises a second end cap covering the end turns at the opposite end of the core with an outwardly extending circumferential flange engaged by the hooks, whereby the first and second end caps are clamped to each other and retained on the armature.
