Calculate Performance Curves of BLDC

This example shows how to calculate performance curves for a brushless DC (BLDC) motor. The simulation includes a speed ramp. Ideal trapezoidal modulation waves are used to drive an average-value converter. A triggered subsystem is used to determine the peak torque, power, current, and efficiency values for a given speed.
