Question one
A 20-hp, 240-V, 76-A,900(r)/(m)in, series motor has a field winding of 33 turns per
Pole. Its armature resistance is 0.09\Omega , and its field resistance is 0.06\Omega . The
magnetization curve expressed in terms of magnetomotive force versus EA at 900
(r)/(m)in is given by the following table:
Armature reaction is negligible in this machine.
ay=y_(1)+(x-x_(1))((y_(2)-y_(1)))/((x_(2)-x_(1)))
y,= linear interpolation value
x,= independent variable
x_(1),y_(1)= values of the function at one point
x_(2),y_(2)= values of the function at another point
