ABSTRACT:
An electrical machine has a stator, and a rotor defining an axis of rotation, the stator including laminations located along that axis, the laminations having protrusions, the protrusions on each lamination being circularly spaced apart about the axis to define cooling air flow passages, and a fan mounted on the rotor to effect flow of cooling air into and through such passages as the rotor rotates.
