Motor Control

Has anyone done any brushless DC motor control using the NIOS? Specifically using a scheme that uses the back emf for sensor position. Any assistance would be appreciated. Rick

elan,

Thanks for the reply. I'm not trying to steal anything from you, but I was wondering if you did the commutation in hardware or software? The reason I am asking is that we have a platform that was designed by a mechanical engineering group within our plant. We work in a EE/SW group, and was asked to evaluate thier design. Their design consisted of two DSPs, one for motor control and the other as a general purpose controller. The design is only on paper right now, and none of the motor control has been written. After a preliminary review, we came to the conclusion that 2 DSPs was overkill. Now we are looking for additional ways of BLDC control. We have not ruled out the DSPs - they have their place and are an excellent method of motor control. The NIOS came in as a possible solution for cost and obsolecene issues, and I just doing a little homework for now. I was just trying to get an idea of how many BLDC motor designs use the NIOS.
