simulation of Brushless-DC-motor

has someone done a electromagnetic simulation of a brussless DC motor in Ansys?

i have some idea - but for this i need to know how to simulate (calculate) parameters for a brussless DC motor.

is possible to couple this em - simulation with a pneumatic simulation of a blower?
could this also be done in Ansys or it's better to use CFD.

please ineed to know how to simulate sensorless BLDC motor (using Back EMF technique) with matab
