Under the mask for BLDC (Brushless DC Motor), there is a resistor and a variable inductor. How can I calculate the value? I’ve been using the exported data csv to calculate…however I am unsure on what formula to follow t…

Hello, I am wondering if there is any possibility to increase rotor speed of BLDC and still have the same voltage? I am using PWM for gate signals and they are already at their top level (duty cycle at 99%). By doing so…
