So, I got this Tarot 4006/620kv motor, yeah, the brushless one. I heard some folks talking about how it’s good for those multi-rotor drones, you know, the ones with four or six arms. I’m thinking of building one of those, a hexacopter, maybe. Anyway, I’ve been tinkering with this motor, trying to figure out how it works.
First, I took a good look at it. Seems well-made, all CNC machined and stuff. Feels solid, you know? I read somewhere that it’s meant for long flights. Apparently, if you use it on a drone with four rotors, it can handle up to 2.8 kg, and with six rotors, up to 4 kg. That’s pretty good, I guess. I also got some of those “Martin Folding Paddle” thingies to go with it. Not sure what they are exactly, but they look cool.
Playing with Magnets
- I opened up the motor casing, carefully, of course. Don’t want to mess anything up.
- Inside, there are all these magnets, lined up in a circle. They’re strong, too! Almost pinched my finger.
- Then I counted them, you know, just curious. I didn’t count all of them though.
- I noticed they’re arranged in a specific pattern, like, north, south, north, south, all the way around.
I tried spinning the motor by hand. It feels smooth, no weird grinding or anything. I guess that’s what makes it “efficient,” as they say. I also connected it to a battery and a speed controller, just to see it spin. Man, it’s fast! And pretty quiet, too. Not like those old brushed motors that sound like a swarm of angry bees.
Now, I’m not an expert on this stuff, but I think the way those magnets are arranged has something to do with how the motor works so well. Something about magnetic fields and electricity, blah, blah, blah. I’ll have to do some more reading on that.
Anyway, that’s where I’m at with this Tarot motor. Still learning, still experimenting. I’ll keep you guys updated on my progress. Maybe I’ll even get that hexacopter built one of these days!
