Loaded unlimited hub motors experience?

The cone washer is used to apply a fuck ton of clamping pressure on the axle, because of the slop having 1 unit of force against the hanger face will have more than 1 unit of force applied radially around the axle, it’s just that friction that prevents the core from rotating

There used to be a serrated washer that would bite into the hanger to prevent rotating but it doesn’t really help so they don’t tell us to use it anymore

Were these from that recent bout of refurbished ones they were selling for the cheaps?? :sweat_smile:

Isn’t radial force just cos theta times axial force where theta is the taper angle? Meaning at best (in an illlogical case) you’re getting 1:1

Or am I just being dum

It’s also possible I don’t understand the setup since I don’t exactly get where this washer goes and what it touches .

The axial force on the motor applies a radial clamping force on the axle because of the slope of the cones

If the cone was infinitely long it would have an infinite amount of radial clamping force for any amount of axial force

There is a matching cone on the inside of the motor core

If the cone was infinitely long, its recycle value would be too great to use on a skateboard. You’d almost have to sell it and use something else.

But imagine how much torque you’d get from an infinitely long motor :yum:

Why? What does the length of the cone have to do with it? Isn’t it just the angle of the taper?

I mean they are dependant

eh not rly. you can have a large angle, infinitely long taper or shallow angle, very short taper.

of course :joy:

Awwww balls. I hope they do right by you and replace the damn thing. I know it said no warranty for mine but they also said they were tested and in good working condition.

Given the same diameter they are

Anyone happen to know the screw specs on the motor liner cover? I think its m5x6 but the m5 bolts i got don’t thread. Maybe fine pitch or imperial?

I think imperial actually. The outer green metal ring is defo imperial. Don’t know the rest for sure.

Thanks. Confirmed it’s 10/32 - the length was ambiguous.


The smallest I could find compared to the actual size. Hoping that the extra length won’t affect anything (Never pulled off the motor liner or cover, so idk what’s down there) but I have some lock and flat washers to take up the extra space if it fouls.

McMaster has almost every Imperial bolt you can imagine. Metric, not so much.

Preference of wire route 1 (out then in w/ connector clamp) or 2 (‘straight’ forward)?

The default connector clamp sucks

I’m kinda torn, on the one hand the first is how Loaded intended it to be, it’s a lot neater, and this gives a lot of slack for the motor wires to move in turns; but on the other hand that was supposed to be for RKP trucks not narrow TKP so it’s a lot more stress on the wires than their should be, the plastic connector feels like junk and since it’s the old school pattern I only get 1 proper hole to hold it, and it makes it more obvious it’s electric which I wanna avoid
