Determine the motor speed at a specific line current, Electrical Engineering

Assignment Help:

Q. A dc series motor operates at 750 r/min with a line current of 100 A from the 250-V mains. Its armature-circuit resistance is 0.15  and its
series-field resistance is 0.1 . Assuming that the flux corresponding to a current of 25 A is 40% of that corresponding to a current of 100 A,
determine the motor speed at a line current of 25 A at 250V.
