The MÁV series V41 was an electric locomotive of the Hungarian state railway Magyar Államvasutak (MÁV) and the first series-built electric locomotive to work according to the Ward Leonard system .
history
The locomotives were ordered for the electrification of the main Budapest - Miskolc line in 1958. In contrast to the electrically operated Budapest – Hegyeshalom line , the line should be electrified with 25 kV 50 Hz. In order to be able to use the locomotives freely, they were designed as two-system locomotives .
Later locomotives of the V42 series that looked almost the same and had a higher output were procured.
They were initially used in the Budapest area and carried freight trains . The vehicles only proved themselves to a limited extent, as the construction was poor and the performance was too low. After 1970 they were retired and continued to be used as a car heating system. The V41.523 has been preserved in the Budapest Railway Park .
technical features
The locomotives work on the system of a Ward Leonard converter. This system was previously tested in the production of an electric railcar . In principle, it consists of a prime mover that drives a generator at a constant speed. In the V41 , one drive motor drives two generators. The speed of the synchronous motor and the generator are 1500 / min. A generator supplies two DC motors in series . The variable speed of the running traction motors takes place through the excitation current of the generator. The drive system allows a very sensitive regulation of the speed of the locomotive with 16 speed steps.
