The vehicles of the series 30 and 32 of the Italian Rete Adriatica (RA) for the Veltlinbahn were three-phase alternating current powered railcars . They were four years after their delivery in 1902 with the takeover of the RA in the state Ferrovie dello Stato (FS) under the groups E.1 and E.2, with numbers E.1 to E.5 and FS E.21 to E.25.
They were part of the electrical equipment for the lines of the Valtellina Railway in Lombardy, all of which were designed and supplied by the Hungarian company Ganz . In addition to the 10 electric multiple units for passenger transport , another 5 electric locomotives ( RA 341–342 and RA 361–363 ) for the same power system of 3,000 volts with 15.6 Hertz frequency were delivered between 1901 and 1902 . a. handled the freight traffic.
Type differences
The RA 30 were 1st class with a saloon and 24 seats ; the RA 32, on the other hand, has 24 1st class seats and 32 3rd class seats.
drive
An electric motor was integrated into each wheel set ( single axle drive ). The outer wheel sets of the bogies were driven by high-voltage motors, while the inward-facing wheel sets had low-voltage motors of 300 volts. At the speeds systematically specified by the three-phase system, this configuration enabled by switching the motor groups on the one hand and the number of poles of the individual motors on the one hand, a smooth start-up and, on the other hand, an at least roughly graduated speed regulation depending on the current requirement.
