Abstract
In a dynamoelectric machine, a stator assembly is mounted directly in a bore of a housing for surrounding a rotor. The bore has an axially extending slot. The stator assembly includes a plurality of laminations bonded together in a stacked array for circumferentially surrounding the rotor. A given number of the laminations at one end of the stator assembly are radially enlarged to define a tab-like flange for projecting into the slot of the housing to prevent the stator assembly from rotating relative to the housing. Complementary axially abutting shoulders are provided between the stator assembly and the housing to prevent relative rotation therebetween.
