Answer / rakesh

now when load torque increase then to remain in the steady
state i.e to make the developed torque equal to load torque
the corresponding armature current increasee ( t@i) so the
increased mechanical power comes frm the increased armature
current

pls tel me the electric train traction motors name plate details like rpm,torue,voltage,amps,watts..ect..
