INTERNALLY-LOCATED ROTATING UNION FOR A MOTOR-GENERATOR SET

Abstract

A motor-generator set, which has a rotatable central shaft, AC and DC rotors tandemly-arranged along the shaft for rotation therewith and a liquid coolant flow path defined through the shaft and rotors, includes rotating unions mounted internally of the shaft within first and second axial bores defined in opposite ends thereof. Liquid coolant enters the axial bore at one end of the shaft and exits the axial bore at the opposite end of the shaft via the internally-located rotating unions. The rotating unions each includes features for collecting leakage of residual amounts of fluid from the bores past the unions, and fluid transmission coupling features being mounted respectively to the rotating unions for attachment to transmission lines for supplying and discharging fluid to and from the unions.
