Stupid question about Neu motor - RC-Monster Forums

Nard Cox · 10:43 AM

(As we all know there are no stupid question ... only dumb people who ask questions)

I have a Neu 1515 1y 2200kv Finned with those nice stiff motorwires that come out of the windings directly.

I wanted to solder a wire to it in a 90 degree angle ... but that's sheer impossible (unless someone gets me a nice walk through or something)
So I thought ... why bother with soldering and stuff....

I just cut of a wire and pushed the Neu motor wire in .. no soldering what so ever (I can push it in further if needed). It's a pretty tight fit but I'm afraid of bad contact or what ever, should I be ?? The contact between motor wire and normal wire is pretty optimal I guess. It's more optimal than the below option right? Because with a bullet it's 90% surrounderd by solder.

Thanks!

FYI Firstly do not shorten those motor wires - They are actually the end of the windings and a little further back are coated in a laquer.

Secondly no I would not just push the wires together - It will vibrate apart in an instant.

However - Now you've pushed them together you could just heat it up and feed solder in to create a good connection..

I'm not shortening the wires, but thanks for the tip.

Against the vibrating I could try to use zipties or something ... but

I will try your tip. Maybe I will strip a few mm of the silicone to expose the wire a bit more to make soldering easier.

Man I REALLY hate soldering this motor :D

Just thinking
You may could cut a slot in the side of the male bullet like this

My 2¢

Also been playing with that idea but the fact remains that it will have a very small contact with the actual bullet and a lot of solder will still be needed.

Buy some bullet connectors that have the additional hole in the side (meant for 90 degree joints).

Nard- Don't be afraid of soldering your motor. Solder is our friend!

You won't overheat or wreck anything by soldering. Anything you do solder can be de-soldered and put back to normal.

Connections need to be SOLID. Solder mechanically locks the connection in place, and helps to make a good connection.

Learn to solder. It use to intimidate me too, but I just practiced and now i do my own soldering. There are lots of useful youtube videos showing how to solder. Good Luck!

I don't minder soldering Harold ... but those (damn) Neu wires .. the solder just drips off :D

Anyhow, I went to the LHS and he fixed it for me:

Just kidding I'm not pulling a ''FreezeByte move'' on you guys, I did it myself. I put the motor wire in and cut about 2mm off of the silicone and put some solder on it. The connection is solid and during my test driving nothing heated up (besides the normal heating).

Awesome! Nothing makes a car look neat and finished like nice tidy wiring. Good jobe man!

Man, poor Freezy sure takes a beating on this forum... Wonder how that mexican food is treating him?

Thanks. Now I just have to mount the on/off switch and it's done. I'm wondering how long it will last this time. The previous one held up suprisingly well :)

whitrzac · 08.04.2010, 08:55 PM

cut the switch off...

Nard Cox · 08.05.2010, 04:41 AM

@ whitrzac, that would be the smart thing to do right ... I hate the fact that I have to disconnect the LiPo for the system to turn off. Think I will leave it on for now and buy myself a decent switch and swap it. Suggestions anyone?

@ linc, yeah ... you would almost feel sorry for the guy ... almost. As soon as he will be able to solder it will get less ... or not I don't give guarantees.

no, but a RE-suggestion: Lose the switch. It solves all your switch related problems and forces you to unplug your lipo. Which is good insurance to make sure you don't leave a lipo plugged in and puff it.

Nard Cox · 08.05.2010, 11:56 AM

On my two MMM's the switch also failed (but only after 8 months of use). That it forces me to unplug my LiPo is a good though ... I will reconsider ;)
