How to characterize the BLDC?

[tcad]

Hello,

I want to simulate the control system for the BLDC, but
I don't know how to characterize the BLDC based on the
torque-speed curves? The BLDC model has a lot of parameters,
such as l,r,ke(backemf constant), kt(torque constant),
j(inertia). How can get them from bhe torque-speed curve?

Could you help me or give me some reference site about that?

Thanks a lot.
