LOCOMOTIVES FOR THREE-PHASE CURRENT TRANSMISSION

S Kademann

Abstract

Previous tests with three-phase current motors are described, along with study of transmission from wheel to rail of traction and braking forces. Criteria are given for synchronous and asynchronous motors. A Brown Boveri (BBC) process in connection with converters for producing variable frequencies for running control. Henschel BBC-DE 2500 system for universal locomotives with asynchronous alternating current motors: diesel locomotives, locomotives with overhead lines, dual energy-source locomotives. Test program: running behaviour, supply of direct and alternating current to the overhead contact lines. Possibility of standardising elements in diesel and electric locomotives.
