Patent ID: 7752733

Claim:
A method for making motor assembly, comprising steps of: a) providing a first thin-walled end cap having first inner and outer walls connected by a first integral side wall, the first outer wall defining a first terminal edge, b) providing a second thin-walled end cap having second inner and outer walls connected by a second integral side wall, the second outer wall defining a second terminal edge, c) providing a stator, having multiple parallel laminations defining an axially extending bore to receive a laminated rotor on a rotatable shaft, said stator having axially spaced end laminations, d) positioning said first and second end caps at opposite ends of the stator so that said first edge extends adjacent one of the stator end laminations and the second edge extends adjacent another of said stator end laminations at the opposite end of the stator, e) and locally laser welding said edges to said stator end laminations, only at spaced locations about said axis and at the peripheries of said end laminations.
