    For Sabvoton sine wave motor controller users

    For Kisszabo, and others who wish to use cruise control. When transparent wire is connected to earth, but 3 speed switch is disabled (in MQCON software), cruise is automatically activated when throttle is held still for a given number of seconds (3 or 4, I think). Cruise will be deactivated as...

    For Sabvoton sine wave motor controller users

    For Davidcroatia, and any others wishing to use variable brake. You will need a 'Hi brake' wire as well as the three wires indicated on your Youtube video. When the 'Hi brake wire is connected to 12V (apparently it can also be connected to battery +ve, although I'm loathe to put 84V across any...

    For Sabvoton sine wave motor controller users

    Hi all, Is this thread still active? I've been trying (like so many more) to get reliable information regarding pcb pinouts for Sabvoton SVMC72150. Earlier in this thread some say that J7 pin3 is for reverse function (short to earth), but I can confirm that this is NOT the case with my...

    Removable method of securing motor's axle nuts

    Make your own torque arms from old circular saw blades. Hardened steel will not deform when subjected to torque forces as long as they're accurately filed to fit snuggly.

    I have had a bad experience with OllinBoard

    This is all getting a bit Jerry Springer! Perhaps we should all take a deep breath, and move on. We can all learn from mistakes as well as successes. This level of name calling etc. and general animosity doesn't seem to happen much over on the other threads. Nobody died, and nobody got robbed...

    3000W alibaba hub motor good?

    Flux linkage will be a little bit 'lumpy', as the phases will not all 'see' the same shape/strength field. I suppose it could cause larger parasitic currents if delta configured, but the effect on a wye motor would be marginal at most. Small decrease in efficiency. Bionx motors all have gaps...

    3000W alibaba hub motor good?

    Thanks for your input Zombiess, I appreciate your collective approach. I've been re-reading some of the threads from 2011/2012 to which you have made excellent contributions. I am hoping that we haven't totally hijacked Animalector's thread, and hope he chimes back in when his motor arrives. I...

    3000W alibaba hub motor good?

    I get your point Zombiess, albeit slightly off topic! I was lead to believe that 9C were a reputable business. Justin has been working with them for years. I would have thought that the relatively unknown companies were the ones to be wary of. If purchases are made through Paypal are they not...

    CAUTION! ABOUT THE HYGIA BRAKES YOU PURCHASED FROM ME!

    Hi Zombiess, For what its worth I also think that Luke is correct, but all is not lost. Unless there are issues with machining tolerances, the seals should be available locally in a variety of materials which are either mineral oil or DOT4 compatible (but not both!). If I were you, I would...

    3000W alibaba hub motor good?

    Thanks for your reply Zombiess, and all contributions welcome John, but you're preaching to the converted. I'm a Natural Sciences major, and 20yr physics professional, so the basics are not new to me, I'm simply trying to get to grips with Chinese marketing. There seems to be alot of secrecy...

    3000W alibaba hub motor good?

    Here's the photo of the hubbie. Is the axle on yours (Zombiess' - Nicole motor) held with a key and keyway? Removeable? What about on the cromotor?

    3000W alibaba hub motor good?

    I thought that might get your attention! Note this is all info. from Sunnychen at 9C, and I'm suffering the usual problems getting straight, consistent and relevant answers (no disrespect intended - but clearly language/translation issues). He also seems to have gone quiet since requesting low...

    3000W alibaba hub motor good?

    Thanks for your comprehensive reply Zombiess. I also noticed that the laminations appear quite thin. The 9C version of this motor apparently has a 50mm wide stator, which sounds more like the cromotor (albeit V1 - probably pressed steel armature in stator). I can understand that Greyborg have...

    3000W alibaba hub motor good?

    Thanks for your work Zombiess. You have clearly been very busy! The motor does look a little 'thrown together', but aren't most of the Chinese motor products a bit like this (I'm thinking of Justin's old 9C factory visit video!). Overall it doesn't look too bad, at least on screen. Do you think...

    Greentime controllers

    We need to work together to alert those that know how, to come on board and contribute to the cause of reverse engineering the software and translating the language. Anpaza was wholly unaware of the developments so far until I pm'd him about the thread. Do we have any Chinese speaking...

    programable controlers ?? advise please

    Hi Justlooking, You'll need to open up the controller and look inside to see how the capacitors are rated. If they are 80 or 100v rated then your controller may be able to handle 72v. Check fet datasheet on internet to see if they can also handle the uprated power. If the capacitors are rated at...

    24v brushed controller that can be overvolted

    Hi there, Generic Chinese brushed motor controllers available on ebay at very reasonable prices. I bought a 48v one for about £20 for my recycled double hubbie flat track look alike. Slightly harder to come by than the brushless controllers, but available nevertheless. LVC is set at about 40V I...

    Bionx Battery problem

    Hi, Is this thread finished? I also have a Bionx system with a failed battery (old system - not CANBUS I think). The BMS board is in a real state with some water damage, but the LiMn cells appear to be OK. If any body has an old dead Bionx battery to donate a healthy board from I'd be very...
