oh man... anyway to strengthen the shaft?

Nope, i don't think so. The best thing is to fit it and enjoy the motor for as long as you can. It may be 4000miles or 4miles, you can never tell.

here is a picture of the epicyclic drive from my tongxin middrive project, it has about 4000km on the clock as a front hubmotor. The axle was twisted after a little clush with a curbstone, so I decided to reuse it as middrive motor. I had no problems with a cracked ring or broken shaft yet.

What is the best(s) suited controller for this motor(s)??? Where I can get one?

I have a sensorless motor something similar to this. Its same size and looking through one of the holes in on the side of the motor I can se copper winding. If its geared or not I dont know. When I first plugged in my motor with the phase wires it spun the motor but not the wheel. After I changed phase wires for another setting it spun the whole wheel like a normal motor do.

The motor was old stock like 2-3 years from now. 36v rated 6A or something inscription on motor cover.

I use it with 12s lipo and 15a controller. 20" wheel. No overheating just slow topping out at about 20 mph and takes any hill (15% for comparison goes at 15 mph).

Then it is "geared" in that it has a freewheel/clutch inside it, and most likely a planetary setup using either gears or rollers. You'd have to open it up on the other side to see the gearing type, most likely.

I use it with 12s lipo and 15a controller. 20" wheel. No overheating just slow topping out at about 20 mph and takes any hill (15% for comparison goes at 15 mph).

If you use it with nearly three times it's rated current, you may melt it down if it bogs down at high load or run it very long at it's less efficient speeds. (the motor itself might nto melt, but if it is geared with plastic gears, they may heat up so mcuh they get soft and deform). Just speaking from experience with a similar but slightly larger Fusin geared hub.

Are the Keyde motors Tongxin. I was planning on getting one since you have to keep a really low profile here in New jersey. The website that sells them sells a rear wheel w/ disc set up with the controller inside the hub. this is very tempting since with paniers, I doubt LEOs would be able to notice that I am running an electric motor.

If so does anyone have experience with Keyde?

Thanks
