Do you know what model hoverboard those motors come from, or is there a web site where I can buy them individually, or are they just something you found salvaged somewhere? They look great for me, since all I need from the rotor is the iron ring and magnets.
A guy sells me defective hoverboards for 10e each, and I am never able to say no.
I have 3-4 hoverboards I suspect to have same plastic build, I need to open it to verify.
Most of the time it’s generic or rebranded, so I am not even sure you can find the same reference in another country. Those and those for example look like plastic:
Look at this
A four-motor control almost begs for omnidirectional wheels. By 3D-printing them you would get rid of the slippery plastic wheels, too.
OTOH, a 4WD slip-control would be a good coding exercise.
Be careful how you connect two LiPo batteries. (Two BMS)
My advice: charge each block separately and decouple the outputs with dual schottky diodes
The local scrapyard may just give them to you for free, or for a small tip…
Or I get them at flea markets - some vendors have very inflated prices, but just walk round and ask people… I find going price here in Austria for a used hoverboard without charger and without being able to test it is EUR 5 to EUR 10. At a large market you can go home with 2-3 hoverboards from one visit. So far the ones I’ve disassembled (I have a slight backlog going here) the motors have always been fine inside.
