Re: Electric Surf Board

FYI anyone have any thoughts on the pumps from the following supplier, they also have a 55mm and 80mm setup. Not so sure about the impellers. I am just hoping there are options to get metal impellers. https://www.aliexpress.com/item/4000147399664.html?spm=2114.12010615.8148356.11.3c0572a8NA0K0b This...

Re: Quick but too quick!

Unlikely to be the throttle, can check by putting a multi meter on the signal wire and ground for the throttle you should have a voltage that changes from about 1-4V over its full travel. If its a smooth change from 0-100%, not the throttle. Most likely issue is just a cheaper controller and high po...

Re: Large drone motor for go kart

Kelly controllers KLS range would be good assuming they can match the high E-rpm of the motors if you want them quiet. Otherwise the KHB range would be better for price, will have a loud whine to the motor usually. Seriously tho, that price is frocked. Try https://frchobby.en.alibaba.com/?spm=a2700....

Aus - High powered Chopper 10kw+ Mini-hubmonster

Hello, I am selling off some ebike parts. I have a long chopper/cruiser frame with a mini-hubmonster and a 120v Kelly controller running the bike. Currently the batteries are toast and I dont have the interest to rebuilt it up so I am selling it off. Just add a 120V nominal battery and you will have...

Aus - Powerful Low chopper bicycle 8kw+

Hello, I have my purple monster low chopper bike for sale. I bought it back of the owner I built it for and replaced the battery pack along with wiring up a Kelly controller to make it a much easier bike to handle at 8kw. It had previously been running comfortably at 14kw so it can easily handle alo...

Re: Offset hub alloy wheels

Best thing I can suggest is find a car wreckers and get yourself some of the aluminium space saver wheels from a Mercedes or some European hot hatch car. 16-18" are available in about 3" wide or less. Most single side swing arm setups for motorbikes are even bigger then that at 5". I am also looking...

Re: GM motor/controller, constant "stalling" and stuttering

Well hopefully you do get it sorted with just wiring issue as been the problem. It kinda does sound like that if you are having issues even when coasting down a hill etc. Yeah with the controllers it would be nice if they would hold a history of faults so you could actually track what was causing it...

Re: Sabvoton Overclocking

Should be as simple as open up the controller fine the 2 phase wires that go thru the hall sensors to read the current big square things, prob blue. Cut the wires before the sensors, grab 2x 8awg wires and solder them to the original single 8awg wire, feed one thru the sensor and then use the other ...

Re: Are the ADAPTTO kit $$$ as people think....?

well documented in regards to the adaptto is only for fairly standard hub motors. Go for anything high speed like a mid drive etc or something abit different and its alot harder to setup and get right. Adaptto is going to have a bit of competition with recent controllers coming out with bluetooth di...

Re: Ultra lightweight CV Joint Axles and low RPM Motors

more as a link for a supplier for usable parts in the project he is doing. 500rpm is probably more the at the wheel speed so there could easily be many stages of reduction or even a single large stage using 219 chain as a example would be very easy. Probably one of the easiest in this power range is...

Re: Golden motor 48v HPM3000B problem

Sounds normal to me :) yes try changing the yellow and green hall wire connections first. If that fails try the other 4 hall combinations. 1 should work perfect but may go in the wrong direction tho.

to be honest i have had a few of these motors and the actual wiring between phases and halls does not match on most of them. So please do go through and check the different hall connections, pretty sure i had to swap green and yellow on about 2 motors out of 4. Also in regards to turning the shaft, ...

Re: Solar-Electric Beetle project on crowdfunding

Sine wave controllers are a pretty good idea only if you can get one with great regen settings. Adaptto is one but its also very under used as you would want to be charging the car while driving if its sunny out. I would use John from CRs hub motor 93% efficient, the mid sized one, 2x adaptto minis ...

Re: Adaptto Mini-E/Max-E Owner's Thread

For everyone's info, if your experiencing speed limiting on high speed motors you will find that pwr timing has a large effect on the top speed too. Just make sure you calculate your actual e-rpm so you dont get too close to the max.
