Can u explain : what is supply for train (whether a,c or d.c
).I know that supply is 25000v a.c .But there is rumour that
supply is D.C.
And also explain how lights and fans inside the trains are
working ,and what type of motors are used in trains whether
D.C motors or induction motors .If d.c motor, how it gets
supply.If traction motors are used then what are traction
motors and its functions and how it differs from other
motors and also explain about locomotive .
please reply..............

Answer Posted / sandippatel2310

all indian trains run at 25 kv ac. only in mumbai church
gate area d.c system is still in use.
Lights and fans run at 110V DC system through batteries
under the coaches.
Locomotive uses DC series motor, 25KV is stepped down by
transformer and converted to DC by rectifiers inside the
locomotive itself.
Induction motor not used
DC series motors are used as they have high starting torque.

hi every body i am master student in control engineering and my project is slip control in trains i assumed a Dc motore as traction motor but i don't have characteristics of this kind of motor that is used in train. i want from every body if he or she has the characteristics or information about Dc motor that is used in train give me those information or technical characteristics .
