DEVELOPING A 15 KV SINGLE-PHASE ELECTRIC LOCOMOTIVE WITH THREE-PHASE INDUCTION MOTORS

J Korber

Abstract

Development of five electric locomotives, Class E 120, with three-phase brushless traction motors has been initiated by German Federal Railway after extensive tests with prototype diesel-electrics built in 1971. A 1400 kW traction motor had been produced for the new Bo-Bo units which are to be in service by 1979 and are to be prototypes of a new series of DB electrics. One of the original diesels is being converted for use in the Netherlands as a 1500 V DC electric locomotive with dc/dc/three-phase power conversion.
