what are the methods of speed control of dc motor???
Answer Posted / vijayakrishna
somany methods are used
field control,armature resistence
field control method: we add a veriable resistence in
series with fielled winding to control the speed of the
motor.
armature control:we add a veriable resistence in series
with armature winding to control the speed of the motor.
