Hi,all, just a question if anyone can help. I have I have a total of five black wires exiting my controller,all of which are ground wires with continuity to each other. The question is could I join these together and create a common earth point for incoming earth wires on the throttle,cut off...

Hi,all, I've just finished rewinding a burned out geared hub motor,the problem is when I put the stator back into the magnet bell the cogging effect seems weak. When I touch 2 phase wires together it cogs more but not nearly enough. I've re checked all my windings and all's good ,with equal...

Hi all, a quick rewinding question; Will 1 turn more or one turn less on any single stator tooth be any significant problem? Asking because one tooth on a phase has an extra turn,my bad! Thanks in advance.

Hi everyone,I hope someone on here can help me. I have acquired an ancheer 250w 36v geared hub motor which the windings/sensor board are burnt out. The hall sensors on the p.c.b are strange,I'm unsure which type they are (see images) The centre hall sensor is white for some reason and I can't...

Hi,all could someone advise me. I have a brand new 18v power tool battery. I've removed the 10 cells and separated them/cleaned off the nickel. What I don't understand is they have never been charged or cycled,they are at 3.5v yet have a resistance around 80 mohms. This seems wrong unless it...

Hi,everyone, I hope someone can answer my question. If a 10s5p battery pack is given a continuous 15 amp load,what would the load be on each cell? I.e. would current be divided equally in each cell (3a) or will each cell need to provide 15 amps? Thanks in advance for any info.

Hi,I just need a little advice,please. I've acquired 50 brand new Samsung high drain cells and I want to make a 10s5p pack. I have a spot welder and will be fitting a BMS. 10 of the cells are 1500mah and 30 are 2000mah they all have resistance around 25mo. My question is,can I mix these cells ok...

Hi all just a question about my rear geared hub motor. I've noticed when doing some maintenance that I can move the wheel/hub a small amount before the internal gears are felt to engage. I'm using it with a locked freewheel clutch so it's pretty much a direct drive. Is it normal to have any free...

Hi, all I am currently stripping my 250w dapu rear hub motor to repair phase wiring. I have unscrewed the drive side cover and removed the freewheel and planetary gear assembly, however I'm unsure how to remove the main motor assembly. The images enclosed show that the sun gear assembly won't...

Hi, all I have a sensorless hub motor with an intermittent stutter which I suspect may be down to the hub wires. I have tested all three phases with everything disconnected, they are all around 0.5 ohms which I believe is ok. The problem is when I test each phase if I move the wires slightly...

Hi, hope someone can help. I was running my 36v 250w geared rear hub motor with a locked clutch and sensorless dual voltage controller without any problems, however I decided to overvolt to 48v for a Little more power. Unfortunately it now hammers and knocks on acceleration. The motor looks...

Hi, I've just bought a throttle for my ebike and it says it's 10/1 Can anyone explain what that means? I suspect it means a ratio of some sort. Help appreciated Thanks

Hi, I've recently bought a half throttle for my bike. It says it's 10/1, I'm not really sure what this means. Is it a ratio, perhaps? Help appreciated. Thanks in advance.

Hi I've converted a 250watt geared rear hub motor to work sensor less, by welding the clutch and using a sensor less controller. It works quite well but judder a little on hard acceleration. I'm considering fitting hall sensors on a pre soldered board. Would I have to 'mill' out the stator for...

Hi,all, I have a geared hub motor originally with speed sensor (now disconnected) and I am running it as sensorless with a dual mode controller. It seems to judder a lot,and the question is can I add hall sensors between the stator slots rather than buried into them? Does anyone have any links...

Hi,all, I have a large amount of good nicad power tool cells. The question is; would it be worth making a large 36v battery (2x18v in series) for a 250w pedelec Thanks,in advance.

Hi,I have a brushless,geared/freewheel motor 250w, running sensorless on a dual mode controller. I have jammed the clutch in the drive position,and used self-learn. The problem is; when accelerating it hammers intermittantly as if throttle signal is lost,or the stator/controller are out of sync...

Hi,all just a quick question,is it possible to run a geared hub motor in sensorless mode without the torque sensor connected. Well, for testing purposes at least. Thanks in advance.

Hi,all. I'm getting a sensored/sensorless chinese controller,which I 'll be running sensorless. It has a single wire labelled 'signal' and I'm unsure what it does. I want to fit a brake lever motor cut off,could this be implemented? The only other available wire is 'brake high' but it may not...
