im also in need of good motors and those look great. i sent an e email this week but no replay yet… @mackann any news on those?

They came back to me by mail, and said they would need 70 days as the motors need to be fine tuned before being sold

like with some kind of tuning fork?
I’m sure they sound fine

thanks for the update.
dont know if i should wait then, these sure look like they worth it though
After several batches of test them to make them perfect they are finnaly ready.
Only a few available to order here:
Will ship in 15-30 days

Wow those are some beefy motors. Talk about battle hardened!

Does encasing the field windings like that result in a trade off between robustness and thermals?

Except the only thing that ever broke on the original version was the big end bearing and that’s not really been addressed here.

In my experience, not really.
Dis my pile of deads.
Overheat?
Damage to magnets?
Sensor failure?
Nope, every single one died of bearing failure long before anything else broke.
I have yet to be able to fix one.

They can, can’t say how I know, but I’ve taking apart and putting together a similar motor at least 20 times in the past weeks
The big bearing is press fit on the motor body, and with a slight tight fit on the can
Pretty easy to open the motor, but you need to make a jig with a lever, just pulling the can will get you nowhere
To take the bearing out, you need a bearing puller (that thing with 3 claws that you turn a threaded rod to pull the bearing out, forgot the right name in English)
To put a bearing in, as a old teacher of mine you say, you need a lot of faith. Just kidding, but ideally you need a press with an purpose made adapter to press it in, and another adapter so you don’t put any force on the windings.
The janky way I’ve been doing since it’s my own motors and won’t go to a customer is using another spare bearing and a piece of wood to really carefully and slowly hammer them in, as soft blow of the hammer as possible, and going all around the circumference

Once I got the right-ish puller tool, swapping out that bearing was a doddle.
[Edit] Fwiw, the image does look like it uses a higher quality sealed bearing than Maytech normally carries.

Any word on the performance and reliability of these motors? I’m looking to purchase a set for a high performance build, but haven’t heard any reviews yet. Thanks

I’ll be making a build with these in the next month so I’ll let you know if you’re still wondering by then lol.

Did you ever complete the build? How are these motors?

not yet, still waiting for parts to come in! I’ll let you know once im finished.

Yes sir. I can send you specs and pics of the build if you want. I’m in love with it.

Hell yeah man - post some pics and specs. Let’s see it!

I am interested in those motors but questioning some of it. Your old 6396 motors had a stator size not much larger than that of a Flipsky 6374 and probably equal to their 6384.
That motor is if anything a little lighter than that 6396 and has a thicker can which is some of that weight. The can is more weight and although higher thermal mass I would guess it gives off less heat. There are better ways to protect a motor than making it thick and heavy.
Can I get the stator size?
It seems really similar to this one on Aliexpress. Is it the same manufacturer? They rate the power a little more conservatively than you too.
