Abstract
A stator core is assembled by stacking stator core laminations on pipes spaced in regular intervals circumferentially from one another around the outer peripheral edge of the stator core. The laminations are held on the pipes using crimps in the pipe at either end of the stack length. The stator can be integrated inside an electric motor in such a manner as to greatly enhance the cooling capabilities, and will improve the manufacturing quality of the stator core. Further, cooling media can be passed through the pipe to increase the cooling effect.
