I have a 6 magnet setup on a 750W motor and it is causes unwanted bursts of torque. I would like to try 12 magnets to see if it is a bit more predictable and smooth. Great video btw !
Interesting! Bobby Thanks for watching, I've tried different numbers of magnets and found the voillamart controller doesn't seem to like any number other than the magnet ring that the kit came with, it must be programmed for particular magnet ring, i've heard that some controllers are programable to suit your magnet ring number. Hope you succeed with the trial regards Mr f
Hi Robert I'm messaging you here, because i just found a recent message from you that was for some reason hidden in my YT spam box, tried to tick it to come through to my normal messages so i could reply but i can't find it now, just to let you know i wasn't ignoring you, I can't reply now because i forgot what the long message was about. Sorry for that cheers Kev
@@robertmotion Hi Robert, Sorry about that, the notification only just popped up, it's not like me not to respond straight away, this one slipped through, again apologies, bye the way did you sort the bike out then. atb Kev
@@MrFactotum i have not. I put it down for a while, while im building my shop, Ebike Repair NYC, LLC. im gonna take a look at it in the near future. I still have my notes i took from your video. I only run into trouble with this particular type controller + throttle. hopefully when i pick it up again, time away to absorb will pay off. if not, i’ll definitely reach out again. /Bklyn👑
Interesting it did it on a hill. I'm converting a folding bike with 20" wheels. As the bits are all bought seperat and no idea what to get, I got a 12 magnet. My theory was the controller has to turn smaller wheels faster. They are like a low gear for the hub motor. Maybe your controller tries to overload because it is trying to drive like it would on the flat? Anyway, just fitting the 12 magnet disc. It will be good to try your solution if it doesn't work.
Thanks for feedback, let me know how you get on, magnet rings come in a variety of different numbers of magnets, there must be a reason for this. Cheers Kev
I'm stuck. I have the voilamart 1000w kit. But the magnet disc fell apart and I fitted a new one - along with a new sensor. But the controller isn't picking up the pedal assist anymore. I have the s861 display and I changed some of the settings but now I'm lost as to the correct settings for magnet etc... on the lcd. I can still ride the bike with throttle but no more pedal assist. It would be great if I could reset this display but I've searched and searched. Any help appreciated. I did strengthen the core of the magnet disc as described in this video with rubber washers.
Hi Rab Sorry to hear your having problems, I don't have an lcd display, mine's just a basic kit, so i have no experience in programming the lcd, can't you factory reset it, there must be a way to do it. When i have time i will try and search for s861 to see if i can find anything. The magnet disc, from memory, i didn't strengthen the centre with rubber washers i made a brass disc and riveted it on i think i did another video on that. Have you got the distance from the magnet to the sensor correct, try closer or further away from sensor, also have you put the disc back in the correct direction, if it's the wrong way round the poles on the magnets won't be recognised by the lcd. Hope this helps and good luck. regards Kev
The cadence is looking for you to be NOT PEDALING so it knows when to help you, so if you have more magnets it looks like you are having NO trouble so it stutters.
eyup ashley the only thing that matters is having the magnets facing the sensor with the correct pole of the magnets towards the sensor, or the pedals will work only in reverse hope that helps regards kev
Hi GE thanks for feedback, it's a while since i did the video, just give me the time position on the video so i can take a look what you mean. thanks again Kev
