Driving the mechanical port of the AC7 model generates output on the electrical lines, but the output does not correspond to how a generator works. (For example, increasing the ohmic value of the electrical port load increases the power through the load, exponentially.) I suspect the model is only designed to be a motor, not generator. Is there a generator model available modeling a three phase brushless DC motor (of a few hundred watts)? I need to model a BLDC motor braking a mechanical load, using electrical resistance connected to the motor coils. Thanks.
