Dynamoelectric machine coil spacerblock having flow deflecting channel in coil facing surface thereof

摘要

A dynamoelectric machine includes a rotor (10) having a plurality of adjacent coils; a spaceblock disposed between adjacent coils so as to define first and second cavities adjacent the spaceblock and between mutually adjacent coils; and the spaceblock includes a channel (144) disposed in a coil facing surface (146) of the spaceblock for intercepting and redirecting a circulating coolant flow to the first cavity (160).
