A permanent magnet DC generator has a
\(k\phi\)
value of 8 Wb and RA of 13 ohms. The prime mover rotates the armature at a speed of 1000 rpm. Determine the no-load voltage, the full-load voltage, and the torque required by the prime mover at full load if the full-load power required by the load is 3 kW (assuming most of the power is delivered to the load) neglecting rotational losses.
