Could anyone tell me how to model an electromagnetic brake ( for example a particle electromagnetic brake ) in SIMULINK?

Hi!
I used simulink models avaliable in the matlab 2013a/2018a for regenerative braking. My simulation used bldc motor with VSI, I gave torque and speed profile so when the torque is negative (that is we are providing braking torque) the speed decelerates. During this braking action, battery get charged (though soc was very minimal).
Also, I used my VSI to act bidirectionally without additional boost converter.
Hoefully this helps you... let me know...
I have rebuilt your model with some modifications and attached it to this answer.
Some notes:
- You can measure the wheel speed with an Ideal Rotational Motion Sensor. You can also simply view all the Simscape simulation results in the Simscape Results Explorer, which means you do not have to have extra sensor blocks in your diagram
- I put a transfer function in to smooth the application of pressure to the Disc Brake.
- You can enable thermal effects in the Disc Brake, which would allow you specify lookup tables for the static and coulomb friction values as a function of temperature. You could vary the temperature of the brake to get different behaviors.
- Another option for varying friction is the Loaded Contact Rotational Friction block.
