The nominal terminal Voltage for the motor is VT 300 Vand total value for field circuit resistance for al conditions si Rf-150 . Under ful load conditions (nominal load), find the internal generated Voltage (EA), excitation circuit current (field current) (If), (total supply current flow, from electrical source) line current (li), electrical input power (Pin) supplied from the source.
