Can someone point me to a brushless DC generator model (not motor)?

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.

Hi @Hwel
Is it possible that you could provide me with your simulink file. I am new to Simulink and I am trying to do a project envolving a brushless DC motor working both in motor and generator mode.

AC7 is BLDC motor drive not a BLDC motor model. You need to use one of the following:
- FEM-parameterized PMSM of Simscape
- Surface Mount PMSM of Powertrain blockset
- Interior PMSM of Powertrain blockset
- Permanent Magnet Synchronous Machine from simscape/power systems/specialized technology/machines
