With a 500hp shunt wound DC motor, at 1800rpm, 500Vdc, FLA is 800Adc, Ra is 0.025 and Rf is 400. What would Va need to be if you wanted the motor to operate at 1000rpm at rated torque. Keeping the field current constant. What would be the no load speed?

So if I have the following,

Pout = 372.85kW, Torque = 1978.18N-m, Ia = 800A, Va = 500V, Ra = 0.025, Rf= 400, Eg = 480V, Ec = 480V, Ec in terms of V/rpm = 0.267V.

Va for 1000rpm should be 287V.
