The much simpler "6 step commutation" discussed in the video can give almost as good control at low speeds, but the magnetic field you create in the coils isn't necessarily perfectly aligned with your motor's magnetic field, which means some of the magnetic force generated is just pulling on your bearings and not driving the motor.

You can use entirely digital PWM switching to create that field, as the natural filtering effect of the motor coils smooths it out, and the resultant driver & motor is highly efficient.

When you want good low speed control of a brushless motor, the gold standard is a high resolution encoder (often magnetic) coupled with "field oriented control" - which is essentially using your 6 drive transistors to create a magnetic field which is exactly 90 degrees ahead or behind your permanent magnet field. There's no need to add an intermediate smooth analog stage (which is what a true DAC would give you) - because then either you drive a linear amplifier and have massive power losses in the drive transistors, or drive a class D type amplifier (which turns your nice continuous signal back into PWM to the drive transistors) and you've just added an unnecessary digital -> analog -> PWM sequence. They act as a filter to PWM drive signals, which means that the resultant current is fairly continuous - much like a class D audio amplifier uses the inductance of a speaker to create smooth sine waves. Three is optimal from a longevity and maintenance point of view, and a offers very good efficiency.Īnd I think you meant 'electric', not 'electronic'.Ī brushless motor controller is basically a DAC anyway - so no need for separate components.Ī brushless motor is essentially 3 large inductors. Two is common enough though because it is easy to make a sturdy two blader prop. And in practice the efficiency gains are offset by complexity, weight (a single blade needs a counterweight) and drag of that weight. A single blade is theoretically most efficient because it can run at the highest RPM before the blade encounters it's own wake again, but there are balancing issues and vibration issues with low (<3) blade count props. Which more or less defines the range of a variable prop, once the tips are nearly flat there is nothing more to gain. So at low revs you run a higher angle than when you go faster and towards the tips of the prop the angle gets flatter as well. This is the reason why variable props exist, to ensure that the prop has enough 'bite' rather than that it just churns the local air. Less than that and the prop will encounter it's own backwash. To explain a bit further: a prop is at its most efficient when it has clean air to work with and that only works if the craft moves forward at least as much as one prop's worth of air in the direction of motion. Higher speed is only more efficient if the craft itself moves at a higher speed. Musk isn't correct though, or maybe you misunderstood or misquoted him. I mostly do industrial automation - PLC, CNC, and robotics projects - and prefer to buy parts off the shelf for 10x the (actual) price of building my own PCB to avoid being the only person on the planet who can support that machine, but sometimes the shelf just doesn't have anything to do what you want.

but I've long since left for Kicad, when my education license ran out and resetting my VM stopped working I looked at the writing on the wall and ran. I hear it's no longer written entirely in Delphi, with the infamous "Ignore segfaults" option.

And when you run any tool that uses a script, you lose the ability to undo past that point. The scripting language is atrocious, but everything is built on layers of decades-old scripts. You get used to hitting Ctrl+Shift+Esc and force-quitting DXP.exe, because it hangs for 30+ seconds when you try to restart it the normal way. "Please wait a moment" is a blatant lie, it should say "I hope you saved recently". It's sluggish, and constantly gets more sluggish. But it's just not better than Kicad, with the exception of the push router.

Some people pirate it - there are loads of Russian forums selling cracked license keys be aware that the software with the cracked license will still 'phone home' and earn you a call from Altium legal in a few years with a lawsuit and your public IP/home network MAC addresses, especially if anyone with a legit license opens the files you produce. Just absurd for anyone who isn't using this professionally.

Sure, you can get a free trial through any of the /yt/ sponsorships, but if you want to continue to have access after the trial it's merely $12,000 for a perpetual license or $355/mo for a subscription. Phil's Lab is another great hardware design YouTuber who also produced some great Kicad content, until Altium paid him to partner with them too.
