Nah - I asked Xiongda a few months ago, and they sent me details of the internals: they say it's technically not possible to use the motor as dynamo.
Did they provide any images/diagrams/specs that you can share here? That would be very valuable info in this motor thread.

Re: Cute Q100 lightweight builds slow mtb, fast road

I was able to run my Q100 sensorless with a Phaserunner controller. That may not help you though since you already have a controller you want to reuse.

Re: Advice needed - charger connector burned out

I have the new charge connector for the battery, and I got a new charger as well just to play it safe. When I get back from my business trip, I'll change out the connector and wrap the battery back up and see what happens with the new charger. I'll be testing that out doors just to play it safe.

Re: Advice needed - charger connector burned out

This was not on the first connection. I had been using the charger with that 5mm barrel connector for over a month before this had happened without any incidents. Thinking back, I had seen it very lightly spark once before, but it wasn't much more than what you'd see from a typical static discharge ...

Re: Xiongda YTW-06 mini hub motor

I have a weird feeling you're gonna find that it doesn't have a clutch :O I had never considered that. It would be totally awesome if this little geared hub motor didn't have a clutch. Being able to do regen with the small 13s2p pack I have would be pretty awesome. I'd just have to figure out how I...

Re: Xiongda YTW-06 mini hub motor

Thanks a lot for the update. Looking forward to seeing it's guts. Pretty impressed that it's taken the power you've given it so far! My guess is that it's like the MAC.. it can dish out a LOT of power, but at a certain point the heat buildup gets exponential. When you try 15A, take a few hand temp ...

Re: Single-speed track stealth ultralight

What brake levers are those? They look like drop bar interrupter levers, but that's not a drop bar. I've been looking for a solution for crowded flat bars. Those were just the generic, no-name 2-finger levers that came with the bike. I ditched them when I went to bullhorn bars. I think they are cal...

Re: Xiongda YTW-06 mini hub motor

I posted in another thread that I burned out my charger connection on the battery, so since the bike is going to be down while I wait for new parts to arrive, I decided I'm going to open the motor up and take a look at the clutch. While I'm at it, if its not too difficult, I'll get a look at the oth...

Re: Xiongda YTW-06 mini hub motor

I wanted to update you guys about the motor. I've been running the motor at 48V nominal and 12 Amps for a couple of weeks now. The motor has performed very well at these power levels in a 700c x 25c wheel. My commute is pretty flat though with an total climb height of just 300 feet over the course o...

Re: Xiongda YTW-06 mini hub motor

Has anyone measured the output wattage at 48v with the stock controller? What is the top speed at 48v with what side wheel? Do they program the controller for max speed based on wheel size? I'm wondering if telling them I'm putting it on a 16" rim then building a 26" would it go faster? I haven't t...

Advice needed - charger connector burned out

Hey guys, I had an issue when I went to charge my battery. As soon as I touched the charger connector to the connector on the battery, there was a large spark and a pop and the connector got burned out. It actually vaporized the inner positive pole of the female barrel connector. For reference, I'm ...

Re: Compact Field Oriented Controller, ASI + Grin, limited run

I have very mixed feelings about the Higo connectors. They look nice but aren't something we can DIY on a piece of cable, as far as I've seen. If they are then where are the DIY kits? I also really like the Higo, but find nothing for the DIY fella, and availability and pricing of pigtails is disapp...

Re: IP67-spec throttles?

Generally, a hall sensor is going to be safer in the rain than a potentiometer throttle. One option you have is to disassemble a hall throttle and seal off the wired bits with some silicone. Another option is to make a 3-button throttle as I had designed in my build thread , and use IP67 rated butto...

The big, non-waterproof 5-pin and 6-pin connectors for the halls and cycleanalyst are a bit of a pain to work with when trying to make a clean build and keep the con...

Re: Single-speed track stealth ultralight

The 3.5Wh/m comes from the entire ride, but in all honesty, since I don’t use the motor at all for some of the ride, I’ll need to adjust that. I am probably using the motor for 7-8 miles out of the total 10. So that’s actually more like 5 Wh/m (35Wh / 7 miles). Which is more like what you’re seeing ...

Re: Single-speed track stealth ultralight

After a week of commuting I've decided to bump the amps being fed to the motor up to 12. I'd like to get a little more pull from this thing in the few places I do need to use full power. Here's a screenshot of the latest Phaserunner settings for this motor.
