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

Rick,

We are replacing DSPs with FPGA's because we get more flexibility and can use the same HW not noly for BLDC-Motor control - there are a lot of other motor types and sensors/actors in our machines.

I was wondering if you did the commutation in hardware or software?[/b]

It&#39;s a co-design: sine-commutation patterns are done in hardware - field vector control is done in software (not necessary in sensorless operation).
