摘要

In a dynamoelectric machine stator core assembly wherein adjacent packages (22) of stacked laminations are separated by a plurality of radially extending spacer blocks (24), and wherein each adjacent pair of spacer blocks define in cooperation with adjacent axially spaced laminations, a cooling duct, the improvement comprising a plurality of turbulator elements (26) in each cooling duct, each turbulator element extending into the duct from one of the adjacent axially spaced laminations.
