GetOverHere & WireWhiz
Hey, I was just mapping out the best way to slice through resistance in a DC motor for a racing drone. Any chance your mastery in tweaking power curves could give it a competitive edge?
Sure thing, let’s cut the lag. First, trim the winding resistance by tightening the connections and using low‑ohm wire. Then map the current vs. RPM curve in small steps—start at a moderate throttle, increase in 5% bursts, and log the voltage drop. From there, shape the PWM duty cycle to keep the motor in its linear region, avoiding that harsh back‑emf dip. Finally, run a quick hover test; if the motor still drifts, adjust the ESC’s feedback loop to tighten the torque curve. That’ll shave a few milliseconds off your top speed and keep the battery life in check.
