this looks a lot like the planetry gear reduction of a geared hub motor, fixvid. I build quite a few bikes with such a gear reduction with success, there is a very long thread linked in my signature.

This puppy with chinese pedigree is very close in size to the orange D5035 but it's much heavier(~+250g) and at half the price! I wonder if it's more copper in there.. I didn't test it yet cuz i had a hell of a time enlarging the 8mm ID of 11t sprocket to 10mm as this motor's shaft.

I borrowed some pics of the Turnigy 6374 from the eSk8 website just for comparison.fixvid said:Whoah i think we are going too far with the numbers here.. this motor is just a little bit longer than D5035. I expect it to be a little more torquier but i don't think it's stronger than Turnigy 6374. It would be too good to be true at half the price of Turnigy motors.
FZBob said:All that being said, I like the color, and the price at your link is amazing, so I just ordered one. Merry Christmas to me!

What can I say - I'm a sucker for a sexy motor!fixvid said:[And you din't even wait for my review .. may Aliexpress fulfill your wish :lol:

The only difference is that i use 11t sprocket instead of 10t, but i remember using the same on D5035 and it wasnt even close. I tested it sensorless and with the same phase current of 30A. I would say that in this unfair configuration it's a little bit behind D5035 but very close in terms of torque (because of the bigger sprocket). So it seems that it's a little more efficient. I didn't test it with higher phase current but i suppose it has to better otherwise i see no reason for the bigger stator.
Until now i managed to get away without supporting the end of the shaft because it's a little more thicker at 10mm. I will test at 50A phase current and get back with some results.

BalorNG said:please test no-load current using a wattmeter, I'm interested whether I 'overpaid' 50$

I will put at least a clamp meter on the wires and check for current.

Hey, so, did you test it? My Flipsky motor came with defect halls... got a bit of a compensation, but still bit disappointed.

I've tested this one with a wattmeter:

And got 1.5A, which is reasonable.
Btw, it leaks a lot of magnetic field outside.

Hi Balor
I managed to measure the no load current of this chinese 6384. At 14.5v supply i got 0.8A current consumption.
I still think this motor beats everything in this price range. It has enough torque, sounds good and is cheap. Wouldn't go back to turnigy in this setup.

Did you get the motor? What are your impressions ?
BalorNG said:That's is both extremely cool and actually rather worrying: might it have 'underpowered' magnets? That would also explain low no load current, actuall!
But measuring it's REAL torque for amp would require a dynamometric stand...
I received the Mystery 6384 motor a while ago. It took about 6 weeks to ship from China. I have 5 rides on it since the end of January.fixvid said:Did you get the motor? What are your impressions ?
FZBob said:I used the same current limits as the Turnigy 6374, since I worry about cooking the VESC.
FZBob said:The Mystery 6384 has a fairly harsh and somewhat louder sound in comparison.
FZBob said:Overall I like this motor. I just wish it was a bit quieter & more pleasant sounding. However, for the price it's a bargain. I pay more for a tire!
