Web17 de jun. de 2015 · 3. You need to consider both frequency and Kv in driving a BLDC motor, and motor drivers differ in how they take this into account. So, both points are correct. The rotational speed is directly related to the commutation frequency and the pole count. And Kv * rotational speed gives you the back-EMF. Weboff with a slope of −1 over a wide frequency range, as shown in Figure 3. In the ideal case, this transfer function gives 90 of phase margin, regardless of the feedback F.
