Wow! That explains so much. I was wondering why the clutch remained so stiff. The fact that it is located on the rotor explains a lot.
Yeah - they actually call it a "one-way-bearing" to differenciate it from a regular clutch. Still the function remains the same, and I think it should be removed to allow for regen.

If it were that simple, one wonders why no manufacturers do this. I'm betting there's something we are missing. Like perhaps running backwards stresses the gears too much?

Don't think that's the issue. The YTW-06 uses straight and helical gears, which both work the same way in either direction. I think it's rather about preventing overheating during regen (even now, the motor runs quite hot) and cost cutting: regen = you need another controller.

I got the Bafang G310 and can confirm that the clutch is between the ring gear and the outer shell. A friend with identical G310 blew the gears in 1000 km at 1 KW (20 A at 52V). We just replaced them, filled it with grease and limited it to 700 W. We'll see how long it lasts. I'm really curious to know if the YTW-06's gears can handle 20 A without melting.

I've been running my YTW-06 at a max of 54.6V, 20A for about 90 days without issue.

I need to point out (again) that I don't run the motor at that level all the time though. I use a Phaserunner which is a FOC, so the amps delivered are based on throttle. Most of the time I run at 30% throttle which is just 6 amps, and occasionally run at 70% throttle which is 14 amps. I only push the motor to 20 amps when I'm tackling a really hard hill and that's only for about a minute. The motor has been perfect at these power levels without any issue.

If you have a FOC and can control the amps going into the motor you shouldn't have any issues running this at as much as 20 amps. If you have a basic controller however, and you can't control the max amps, then I'd recommend setting a max current of at most 15 amps.

Are you talking phase amps or battery amps?

Battery Amps.

I think max phase amps are set to 35, but I'm not 100% sure of that. It may be in one of my screenshots of phaserunner settings in my build thread.

We've had a hellish summer here on the west half of the united states.. it's been hot, dry, polluted, and everything's been on fire. Riding a bike has been the last thing on my mind for months.. finally it's looking like we're in the clear.

So anyway.
There is a nut on the freewheel side that made my YTW-06 about 142mm wide or so. Take the nut off, and the motor is 135mm wide but a 7 speed freewheel extrudes past the axle and contacts the frame.. :evil:
And the axle has almost nothing for a shoulder, so forget just throwing a washer on there..

I have an aluminum road bike frame here, so i sure as hell am not going to stretch the drops far..
So being that the nut is maybe.. 8mm? i hit it with an angle grinder and hand file and took almost half the width off the nut.

Now i only need to bend my frame about 3-4mm or so to fit the dropout in.
It's off to get spoked and i'll have some feedback on it's power at low levels soonish.
My first major build: 8T MAC motor on a Trek 4500.
The new all-arounder: Leafmotor 1500w on a Turner O2 full suspension.
The wheelie machine: 20" Rear Magic Pie II on a Trek 4300 MTB

If anyone is interested, there is a thread about this motor in a german forum, with many details, including internals:

Image

It appears that the freewheel is actually located INSIDE THE ROTOR, which means when you're coasting, you're still driving the 2 stage reduction gears. Given that amount of drag already generated by this config, I'd suggest modifying the rotor to remove the freewheel, and try the motor with regen enabled. Should be doable - don't know why Xiongda told me it's impossible. Anyone up to it ?
Yes i'm interested! Do you have a link?

I'm also interested to have a go at doing Regen, but i'm not sure where to start with the motor. I've got a Phaserunner, so can set it up. Xiongda sent me a silver instead of black motor, so they sent another and i have a spare to play/experiment with.

I've also got two broken SWXH that i'm trying to make one good one out of. Burnt out the coil on one and the clutch is stuck on the other, but the clutches aren't coming off either of them.. if anyone has any tips! (i've sprayed WD40 overnight, taken off the snap ring and still no luck).

FYI.. mine was defective in multiple ways, and opening it up cast some doubt on the integrity of the design in the first place. Currently in the middle of asking for a refund because i do not want another. It seized after 1 mile of riding unpowered.

Pictures and videos of the gore here:

The gist of the thread is.. don't buy one :evil:

I was able to buy 1 unit through alibaba by sending a message.

Anyway it looks like they are willing to refund me on the motor they shipped that was constructed incorrectly..
I will update that thread i posted when i actually have something in my hands.

Oh really. When did you send them the messages?
I've been getting messages lately after threatening the paypal return. and they're claiming they'll send me a replacement motor in the coming days.

Shame that they've gone ghost on future sales.
