    Hi

    I would like to know whether you are able to interpolate from a DC motors performance curves, for predicting how it will perform as a generator? Whether there are any additional losses that are incurred?
    I need to be able to predict the load torque vs RPM, as the engine driving the generator is extremely sensitive to the load torque. Help is much appreciated!

    thanks
