1000w yesusa hub motor and have questions

[ian.mich]

Here's what it did the second time with correct polarity same result as the first time with reversed polarity
Melted the metal bullets both ends a little too.

either open the controller and poke around, do the mosfet resistance check aswell just to be safe, or get out whie you still can and buy one of these

I've also vaporized the ends like this,scary when it happens.

Good link there also, was wondering where one could purchase individual components for the yesusa kits

talking to me? thats just a cheap high quality custom chinese controller. fairly common of the purchasers of yesusa kits to buy the huatong controller for $30-40 to increase the amp output from 20 to 40, this is just a better option and its about $45. big thread on them here: http://endless-sphere.com/forums/viewtopic.php?f=30&t=40900

With that Huatong controller, I think it is also raises the volts? So you would have to reconfigure your batteries.

How does volts vs amps change the power output of the bike? Like 48 volts 20 vs 40 amps, vs 20 amp 48 volts vs 72 volts.

 

[wesnewell]

You don't need a new controller just to increase amp output. Just mod the one you have. I raised the first one I had to 42A from stop and WOT. No problem after 18 months now. Provides better acceleration and more speed up hills, etc. Controller was a 30A original, so increased watts from ~1500W to ~2500W.

 

[ian.mich]

for sure, but a new controller will have better effeciency.

with the one i linked they let you set the lvc from 30-100, it's a universal controller and the lvc can be changed. The amp output on the regular yesusa controller is 30A and likely 63V caps so with 48v thats 1500W. with the new controller it's 45A and 100V caps, so with 24S lipo its 4500w

Ian thanks for the information.

I know I could probably dig this up in the Hua controller thread but how difficult is it to change the controller LVC setting? And how difficult is it to adjsut the controller when using different voltages?

If you use a variable resistor to set lvc, it's a simple matter of turning to where you want it. That would be the same for any controller. Or you could use a on/off/on toggle switch and have 3 set voltages using 2 resistors on it.

that shows you how to change the LVC and where you could put a turn pot. that's for a 15fet, havent attempted a change with the other controllers i imagine it's the same.

Has anyone added disc brakes to the yescomusa hub motor?

[Haste]

back into the first page of information...how would this kit compare to the GNG kit or a mac hub.

Im running 12s lipo then upping it to 18s. I think the mac will not take this power level anymore>?

 

[ian.mich]

about geared motors, I don't know. the yesusa and its generic hub will probably take 20S 40A until the end of time.

 

[EdwardNY]

Why does a controller need a LVC? I will monitor my own voltages and will not rely on the LVC in the controller.

What would happen if you use a controller that can take 100volts that has a LVC of 42 volts and then feed it 96 volts?

regen wouldnt work, thats it, its merely periphery.

 

[EdwardNY]

SO I could buy the hua tong controller and run 72 volts or 96 volts without having to modify anything on the controller?

dont buy a hua tong. that said i assume so but i have no experience with them. save the trouble and get a 15fet 4410 from greentime for an extra 10 bucks

Curious if anyone knows if the actual hub motors are different in the Yescomusa kits? My best guess is the cheaper kits are the same motor but a lower power controller. Can anyone confirm?? I have a Lyen 12 FET that I want to use and just really want the motor. SO I was considering buying the 36v500 kit just because it's $50 cheaper. I'll do it if someone can confirm the motors are the same. Thx!

Don't know, but if you're willing to put a bit more money and work in you can order a 1000W hub from greentime along with a thumb throttle and a set of spokes, then buy a DH rim of you're choice. my experience has been that the china ebike rims don't hold up like a DH DW rim, especially if you dont buy their spokes and lace it in sapim 12 gauge. Ask for a 48V 1000W hub motor in black with a disc brake adapter. It's internals have the same dimensions as the other generic hubs, but it is impossible to burn them. they can be run with new phases and no holes at 6000w, heated up enough to melt the paint on the outside and sizzle water, but never ever burn.

Who is greentime? Ebay user of forum user?

I can confirm the 48V 500W motors are not the same as the 48V 1000W motors. Using same battery pack and controller, the 1000W motor out performs the 500W motor by a considerable margin. The phase wiring on the 1000W motor is considerably larger too. I have no idea about the rest of them, but they do post the specs of all of them on their website. I also swapped the 500W and 1000W controllers and each motor still performed the same, thus ruling out the only difference was the controller.

Thanks I was wondering about this also.

But after shipping not so cheap.
