Answer Posted / rakesh
now guys it struck to me while i was solving a question ,
pls help me out . now it is known that the armature mmf in
case of a sync motor is leading the field mmf , hence the
resultant air gap mmf is also leading to field mmf , and
since the rotor mmf (field mmf ) always tries to catch the
air gap mmf the electromagnetic torque in any case will
comeout to be in counterclockwise direction , and possibly
never in a clokwise direction .

1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?
