Problem $2(9$ pts$)$

The magnetization curve for a DC machine

operating at $1200$ rpm$.$ You are working with

a machine that is operating at $1500$ rpm and

generating a power of $10$ Horsepower $($hp$).$

Under these conditions, the armature

resistance is RA $=0\mathrm{.}3,$ the field current, IF

$=2\mathrm{.}5$ A$,$ and the field resistance is RF $=50.$

a$)$ Find the developed torque

b$)$ Calculate the current in the armature, IA

c$)$ What is the applied voltage, VT
