ELECTRICAL MACHINE CORE Russian patent published in 2005 - IPC

FIELD: electrical engineering; electrical machine stator cores.

SUBSTANCE: proposed stator core is assembled of electric steel stampings with their stamped holes 2, 3 forming axial cooling ducts throughout entire length of core. Holes 2 of one group are alternating in stampings with holes 3 of other group offset relative to first one to form axial ducts in assembled core having roughness corresponding to degree of offset.

EFFECT: enhanced cooling effectiveness and efficiency of electrical machine.
