Question { 33661 }

what is dc transformer? how it work?


Answer

T/f works based on mutual induction.so if we r
give dc to that it will burn (after saturation) due
to no oposition(eb=0). Although it act like normal t/
f at starting instant. So bye using t/f we can
change ac voltage w.r.t currunt. To change dc
voltage we can use choppers.

Question { Kirloskar, 11823 }

can we run three phase motor by single phase? and what
happens if we do this


Answer

S we CAN a single phase supply can not produce
rotating magnetic field BUT it produce alternative
magnetic field. It can start with low starting
torque if we give prime move(starting means) to
that motor
