FS Class E.380
The FS Class E.380 was a small class of three-phase electric locomotive used in Italy, introduced in the 1900s. Overview The locomotives, which entered in service in a small batch of 4 units, were characterized by a central cabin with two large hoods at each end. Built by Ganz, they had a similar mechanical equipment to the E.360 type. The E.380s showed a series of problems, so that two were refurbished as E.390. Technical details The two fixed speeds were obtained by changing the motor connections. For high speed the motors were connected in parallel. For low speed the two motors were "cascaded" by connecting the rotor of one motor to the stator of the other. This caused both motors to run at half speed. Withdrawal The low power output at the highest speed, and the limitation of use to only two fixed speeds (due to the control arrangement of the three-phase motors) led both classes to be retired after a short service period.
