Noob question thread! 2020_Summer

still convinced direct drive is the future

once i get the time + money together im gonna do a 50kv 80100 motors to direct drive conversion (dunno details but will work it out)

def the way to go for reliable huge direct drives on 155mm strectched metroboards…

I’m stuck with crapa currently. Eventually I’ll upgrade out of it since I don’t like their monarchy business.

possibly this?

half the wire is cut
not sure how that would affect the motor though

im not sure where to go on from here, maybe someone else who experience similar issue can chime in. i’ve never have a motor fail, well except sensor, but HFI saves the day.

is it shorting itself? they look to be touching each other

?? not sure how that works

around half the copper in the connector is ripped and the other half is fine

copper strands touching the other wires? i don’t know, quite hard to tell from the pic

dont think so. as far as i can see the oters are fine

Oh dang. That’s gonna affect the motors a lot. It’s basically a power loss at that point. Unless you can solder that whole part back and make sure it’s not shorting the other side. Because that definitely looks like a good cause of motor failure.

i realise thats gonna cause a bottleneck for amps but it doesnt explain why the motor cant be spun by hand. (i will solder it back together and protect it but i dont think that is the issue)

Do you mean it can’t spin when it has power? Or when it doesn’t have power? It should freely spin without any power in it. The magnets should be pushing to and fro eachother and creating eddy currents. Now if you had power and tried spinning and couldn’t. That cut could be the reason for it since it can cause the eddy current to stop and become magnetic instead.

when it has no power it doesnt spin freely

Hmm. I’ll look more into this, but that wire might be an issue in the long run. Someone else should know if this is the case or not.

definetely will be fixed. dunno if that is the only issue though

Is that wire connect to any of the phase wires that goes towards the esc? If yes, that’s your guy.

currently not but usually it would be

Yeah, it’s touching the other phase wires, causing it to have power and resistance. When you take two phase wires and put them together, it will cause your motors to not free spin due to current lock up.

This could be your problem. See if that wire is connecting to another phase wire. Try to separate it from eachother and see. If yes, you found your destroyer and you have to fix it.

i know about that but i couldnt see any that were touching

will check again and try

that’s phase wires shorting, u should check carefully again

Its definitely that broken wire.
