electrical train works with electrical drive " asystem
consists of motors , gears and belts "
the type of motor used is direct current motor or exactly
dc series motor becas it has high starting torque for
moving the train from the stationary state
Motors used for electric trains are 3-phase induction
motors,DC series motors
3-phase induction motors- from the sub sstation the supply
is 25 KV or 33 KV.Loco consists of a step down transformer
where this 25 or 33KV is stepped down to 750 v to 1500 v.
DC series motors -600 v dc
force or torque is tansferred from motor shaft to pinion,
gear wheel,driving wheel.
First the train receive 25KV supply from the overhead
transmission line and it step down and converts it into D.C
voltage. And given to D.C series motor. Because the motor
needs heave starting torque to move the stationary train.
Electric train runs by using either DC Series Motor or 3-
phase Induction motor
the train receives 25kv voltage, transformer in it steps
down the voltage to 600v ac and then converted to dc for dc
series motor and 750v ac for induction motors.
guys can anybody explain me how s d train is recieving ac
power when it has only one current collector, train can
recieve only dc power may be it is converted to ac and then
stepped down to lower voltage levels and then again
converted to feed dc motors. Am i correct can some one tell
Electic train works by giving supply to the motor through
the transmission line it may be A.C supply or D.C supply.a
collector is used to collect the supply from the
transmission line and it is given to the A.C motor or D.C
motor.The motor is driven by using gears and belts.
D.C series motor, A.C series motor & a.c induction motor
are the motors used to drive the electic train.
how we test a 3 phase motor on single phase supply....?
HOW WE RUN A 3 PHASE MOTOR ON SNIGLE PHASE. supply for
how we verify of a 3 phase motors 6 wire & name thame
a1/a2/a3..b1/b2/b3 and c1/c2/c3 for connecting star delta
starter ........i have only 1 phase supply ? help
