DESIGN, DEVELOPMENT, FABRICATION, AND TESTING OF A SYNCHRONOUS CONDENSER FOR A HIGH-POWER THREE-PHASE TRACTION DRIVE

This report documents the synchronous machine, referred to as a synchronous condenser, which, in the tracked levitated research vehicle (TLRV), provides line commutation for the inverter and power factor correction for the linear induction motor. The machine also incorporates features permitting its use as a synchronous alternator or motor in a wide range of conventional and advanced ground transportation applications. The machine provides a very high specific power density (1.7 kVA/lb) and voltage rating (7150 V, line-to-line, RMS), principally through the use of direct liquid cooling of both the stator and rotor windings and other elements of the machine (i.e., bearings, brushes, sliprings, etc.). Deionized water is used as the cooling liquid.
