I'm using DC Machine block from SimPowerSystem toolbox in Simulink and I would like use it as generator mode. I use the speed as mechanical input and I don't know if this speed must be introduced positive or negative for using generator mode. In addition I don't understand the help and I am confuse about the sign of the output speed and output torque when DC machine is generator.
Can anyone help me?
Best

Hi,
Generator==> I/P(Mechanical)(i.e. Negative for DC machine e.g. (-1 N.m (Torque))--> O/P (Electrical).
