What are your first impressions dude?

I just mounted mine tonight. I have not powered them yet.

First impressions?

  1. They look excellent, no rust spots or anything like that, overall manufacturing quality and consistency is good.

  2. Sensor wires and phase wires are a great length, shouldn’t have any issues on most setups.

  3. The phase / sensor wires come with a preinstalled mesh sleeve, which looks really nice and is sealed at both ends with adhesive heat shrink tubing.

  4. They have quite high cogging force when turning by hand, to me, feels like they will be really torquey.

  5. The shiny logo looks really cool in my opinion, and the finish and smooth angles on the motors look nice.

  6. Very weird, one shaft has a small hole in the end of it on both sides, and the other one doesn’t… Shouldn’t affect anything but very weird. It looks like a centering hole for lathe work, which you’d think would be cut off.

Overall, very good. I think I’ll be putting them on and setting them up tomorrow. Excited to get some more torque on my hummie build, upgrading from BKB 6354 motors.

Oh nice. Yep bumping up to 6374 will be sweet.

Yeah the length of the wires and having the right sensor connector is super.

The mesh did not quite make it to my enclosure. So I added some best shrink…

Ah that looks pretty nice still. I have MR60 on my ESC right now so now I need to decide if I am gonna switch these to MR60 or switch the ESC back to bullets lol

Interested in how this pans out. I got some 190kv 84s and the cogging force is pretty darn low. Lower than the 170kv 74s or 140kv 54s.

Interesting… This is definitely the highest cog torque motor I’ve felt. Granted I’ve never turned a 6374 by hand except an sk3

I feel like we should summon Hummie to tell us what this means :rofl:

High cogging torque usually means higher core losses, but not always

You have two components to core losses, hysteresis and Eddie losses, the first one is is a constant torque that is independent of rpm, the second increases linearly with rpm

So only spinning it by hand doesn’t tell much, you need to measure both to see what motor is more efficient for a given rpm

Example, comparing the TB6355 with some cheap no brand 6355. The TB one has a hysteresis torque much lower than the cheap ones, but the rate of which the Eddie loss torque increases is way higher than the cheap one

So, only considering core losses, up to a rpm point the TB6355 is more efficient than the cheap one, and then it turns. I haven’t compared both, but if I’m not mistaken this point is above the rpm of what we usually use the motors, so the TB wins

Lets make a sk8 technical workshop on the Carve PDX, I think a few more people would join it

Yes, it is, I really like it
I’ve bought a used one on eBay for 90 Euro

I feel ya on that man!

I snapped my humerus snowboarding a few years back. When the nurse was cutting off my beloved jacket I stone cold face asked her “You’re going to sew that back, right?”
Made for a good laugh all hopped up on dilauded.
Hope you’re getting some good rest, those first moments in the morning suck!
Heal up dude!
