It worked! Not so shine like in instructables photo… But good enought to solder that motor again

Once again there are a bunch of most likely fraudulent listings on ebay for SSS 56104 motors. If the seller has no rating or if the price seems too good to be true — be careful.
I ordered my SSS 56104 KV500 from these guys in China. Getting it took exactly 14 days. That’s a week SHORTER than it took to get my Neugart PLE40 from Motion in New Jersey! Go figure.
What I don’t get is that on ebay all offers for the SSS 56104, like yours @sunrise305, have the same characteristics, including 11kW of power, but when I see the available motors labeled as SSS 56104 in this German shop (where @MaB ordered), they have different windings, 14kW instead of 11, higher voltage and current, and they are also heavier.
So why are they called the same and how to tell them apart? If those numbers are correct then people in this forum are running motors labeled as SSS 56104 with quite different power.

My understanding was there are two shaft options 8mm and 10mm. This might explain weight/ power variations from a slightly different internal architecture.
My understanding is there are a number of different KV versions in the 56104 line. I have both the SSS 56104 KV500 and the SSS 56104 KV420 models. I don’t see the KV500 version on the German vendor’s site. Further, the photos they show do not show the marking that appear on the motors that most of us are getting from China. Not sure why or what that means, if anything.
Finally, I am puzzled why I cannot find a website for the mfr directly. Who/what is SSS?

Keep in mind, there are two versions of each motor kv, the 56104 and 56114. The longer one obviously more torque. I had them last year and the difference for one setup was 18kg vs 25kg of thrust, dramatic difference, but if your using a reduction gear, you likely want less torque so you don’t break your gearbox.

Im using a Neugart PLE40 5:1. Its rated to 14Nm nominal and 22Nm Max. My sss360 will never give that much torque to the gearbox. Only possibility is giving it too much RPM or heat as a result. What do you know about the relationship between torque and RPM into these gearboxes? have you killed a few? Id really like to understand this a bit better.
I have a new Neugart PLE40 5:1 siting here on my desk, I have not used it yet. I have gone through two reduction gears already, they just failed under use and I’m not really that interested in reduction gear design right now, my focus is direct drive. These reduction gears just can’t handle high rpms and the heat that comes with that.
You could limit your rpms with controller to keep them lower, and upsize the prop but then prop is getting really big and takes up a large part of your mast length, and more drag with larger duct as well.
Yep, Im fully aware of your focus on direct drive. If that’s all you want to talk about, that’s cool.

VeFoil - Were your previous gearbox failures Neugart or Parker or another brand? Reason I ask is I have seen a number of mentions of Parker gearbox failures on this site. But none for Neugart.

You are correct, the Neugart seem to be better which is why I got one as well. My others were no name brands.
@sunrise305 But with the same kv there are also differences. For 790kv the datasheet looks actually very similar, except for the 14kv - 11kv discrepancy. Which is a bit odd because chinese seller normally tend to exaggerate, not understate: Chinese vs German.
For other kv the datasheets are again very different.
@michion the shaft should not make a noticeable difference, the weight for the two 790kv motors above is also the same.
@VeFoil The 56114 is yet another story, the german shop has those too. Their datasheets match up more with the chinese ones. But I didn’t understand the motor itself, it has 1kW less power and 5k max RPM less, isn’t that only a very small increase in torque? Or is it higher in lower RPM?
I bought a Chinese 360Kv 56114 and the German 350Kv 56114, apparently the same, 350 rotor is a few mm longer than the 360.
This is adjusted by different bronze spacers on the shaft, 350 is still in its box, so I can’t tell how it perform.
I found the 56104 being rated 11KW and 56114 13KW.
Hello, can you tell me the diameter of the screws on the motor shaft SSS 56104: M3 or M4?
thank you
When you say screws on the motor shaft not sure what you are referring to. There are six M4 screws that mount the motor to the MotorGearboxMount. The shaft itself is 8mm and there is an M3 cap screw on the gearbox that binds the motor shaft.
Yes those are M4 x 10mm

I have brand new 56104 kv500 with dealing KV130A esc im trying to sell. Brand new never used was going to build efoil but just ordering one instead. Text me if interested in located in Phoenix,AZ 623.888.2079
Hi everyone, so i want to use the sss 56104 500kv motor and i obviously need a gearbox but i am very confused because of the crazy price diferences i have encoutered when it comes to planetary geared speed reducers.
Ihave found this one ( https://www.ebay.com/c/1443696672 ) which looks very cheap compared to other ones but it seems like that’s all i need.Can this work or is it too cheap, there must be a problem with it that i can’t figure out.
I’ve actually found even cheaper ones like this one: Nema17 Stepper Planetary Gearbox Speed Reducer Ratio 5 10 20 25 30 40 50 100:1 | eBay
Also when it comes to gear ratio what do you recomend? I think that 5:1 is what i need.Has anyone got a similar setup to work well?
