BLDC speed control example

I try to use the pe_bldc_speed_control model, however when I switched to the specify max back emf tab of the motor and I ran again the simulation the rpm dropped to the half of the reference rpm. What causes this?

Most likely the two parameterizations are different. I believe when you changed from one parameterization to another, you actually changed to a default parameterization coresponding to specify max back emf.
