Beginner Question Thread! 2023 Edition

I’ve been at 95% duty cycle, hit a downhill, let off the throttle and speed up past 100% duty. I gently applied the brakes and while they are slightly stronger than usual, there was no issue. This was on the 5.3 FW.

I think there would be an issue when the motor spins up fast enough to go over 60v (12s battery & esc) and you hit the brakes, but I haven’t tested that.

Hey all. I’m looking for alternatives to a 3/4 inch cable gland for water resistant routing of some mr60’s through my enclosure. The glands are functional but bulky. Any other good options? I do not want to mount them to the enclosure. TIA

Panel mounted passthroughs are my preference.

These are confusing requirements.

Without mounting the MR60 to the enclosure, you would be left with only the option of mounting the wires to the enclosure or doing the horrific “lay the wires on the foam and pray” method which is still in a sense mounting the wires to the enclosure, just in a different fashion.

What is the exact thing you wish to avoid? Drilling/cutting the enclosure?

I’m routing the wires through the enclosure using a gland presently. 3/4" as the below pic

It’s bulky though and I’m wondering if anyone knows of something a little more low profile that would allow me to route an mr60 (i.e. a hole that’s at least 18mm wide) that provides water proofing and will take up less space in the enclosure.

Use a pair of mr60/ like a pass through?
Don’t use a gland.
Just epoxy and colloidal silica to thicken it.
Drill hole and file to shape.
Hot glue and nbone dide to hold in place.
Epoxy other side.
Rip off hot glue with pliers.
Epoxy that side.
Done.

Some pics here, NightTrain | 4WD 6355 BNM1s on Steel BN270s | 10s9p p26A DV4s | Hummie deck this has bullets inside and mr60 outside. Waterproofed to enclosure so either side can be easily unplugged.

It’s nice and tidy but I don’t want to panel mount. Appreciate that it’s the choice for most w mr60 but it’s not gonna work w my build. I’ll diy something rubber sheet, contact cement, a hope and a prayer :sweat_smile:

Thx All for the input :pray:

Heated them up with a lighter and managed to hammer them out, thanks!


I swapped in a longer kingpin instead

Epoxy.

Just epoxy the wires through instead of the connector.

Why? If you explain that, someone might be able to suggest a more suitable option

Well, I could make it work by extending the phase wires on the motor but I just spent like a hr soldering longer phase wires from the pcb of the Xenith so I could avoid adding more resistance in the phase circuit and so the mr60s out of the controller sat further outside of the enclosure. I could’ve mounted the mr60s and extended the motor wires easily enough.

I like these individual cable grommets. They are a little tricky to install tho. Pro tip: soak them in boiling water immediately before install.

Sounds like you should desolder the MR60 and feed the wires through the enclosure then, resolder the MR60, then epoxy the wires in place. Add fumed silica thickener to the epoxy and then after that cures you can cover it with a thin layer of runny epoxy to smooth it out if you want to.

That’s a possible solution, Brian. @glyphiks got a link for those gromets?

Edit:

Something like this would work, no?

Those ones are blank, so you need to cut your own hole, but yeah, same shit. I just get them from the local auto store

Yeah, those will work, or you can get ones with holes already molded in them.

If you desolder the MR60s and just run the individual wires, you can also get cable glands with multiple smaller holes like this one.

Brilliant thx @b264 @rosco @glyphiks and @MysticalDork :beers:

Anyone know what connectors the exway hubs use?

higo or a copy of it, since there is no branding on it, but the pins are same location
