    Bafang G062 / G063 Info

    I would not try this project. You will need to machine the stator to fit more wire. I would not recommend a higher gauge wire, I would recommend .5mm wire and just more of them, like 25 strands instead of 15 strands. Machining the stator can damage the laminations in several ways, they can...

    MXUS GDR19-FAT - Most powerful geared motor?

    The good: - Large high torque stator - The motor seems to take heat well, seemingly outperforming the G062- I was able to run 90 phase amps at low RPM (thick sand) non stop for 2+ miles (several minutes) on a warmed up motor - Steel/Nylon gears from the factory - Much stronger cluch/drive key...

    MXUS GDR19-FAT - Most powerful geared motor?

    Its a nice piece, heres some good and bad- Motor ran well sensorless, with a little stutter at startup. I could not get it to run with sensors (which I have heard as being a problem for others from the limited online information). Whoever wired the L1019 must have been a monkey. Red was wired...

    Bafang G062 / G063 Info

    I'm not an electrical engineer, I'm a ebike hobbyist dirtbiker that breaks s*it :D I think that is calculating the phase current at max rpm / max voltage. That would be the lowest phase current. The highest phase current is at 0mph right when you accelerate, or low RPMs. That calculation also...

    Bafang G062 / G063 Info

    You dont need a connector box if you are making an adapter cable. The connector box is if you connect a new cable to a controller directly. You could solder the phase wires directly, but a connector box allows them to be connected with ring terminals. The benefit of doing so allow the controller...

    Bafang G062 / G063 Info

    "Making your own direct L1019" are you saying make this out of the motor cable? Imean you can, but its going to kinda ruin your motor cable if you do it that way. You are going to have a bunch of solder joints and a homemade looking kit and its permanent. If it were me I would solder two cables...

    Bafang G062 / G063 Info

    Here’s a picture of what it looks like. Less clean than a phase runner but not too bad as you can see the hall sensor is unplugged, as I am able to run this controller sensorless.

    Bafang G062 / G063 Info

    I have not seen any alibaba controllers with an L1019 or L1122 plug, atleast not any controllers larger than 25-30 amp. I use cheap chinese controllers instead of the phaserunner personally. Risunmotor sells a 45amp controller that puts out 60-70 phase amps and is programmable (can...

    Bafang G062 / G063 Info

    Nooo windings are past my limit. I do have a melted motor that could use a rewind. I'm no expert in winding. I dont see the point though, it wont add any copper fill? The motors I get are 6.5T (low rpm motors already) so I dont really see the point? But with the smaller tire and venting its like...

    Bafang G062 / G063 Info

    I've had about 6 of these motors, heres some info that may help. G062 1000 / G062 750 / G063 appear to be very similar motors- G062.750 and G062.1000 are nearly identical motors. The primary difference being the phase wires. Traditionally the 750 was sold with Z916 phase wires and the 1000 was...

    Bafang G063 1000 watt motor.

    Agreed. I have not seen any difference in G062/G063 other than the connector. As far as I know the 1122 connector is worse than the L1019, all of the cables I have seen are only 2.5mm2 phase wires, no better than the G062? Seems the G062 is better than the G063, plus has better aftermarket...

    My clutch welded itself. Bike works perfectly fine, the only reason I knew is the sensorless speedometer started working when off the throttle. Took it apart and sure enough the clutch is seized. I also have a welded clutch but my concern is if the gears inside the motor were to seize or lock...

    Rad Rover 60v 64A (4000w) regen

    Thats exactly what I do on one of my bikes. I was able to fit the 12awg phase wires through axle, just couldnt quite fit the hall wires through. Sensorless can be a little annoying, not sure if it limits torque at startup, but otherwise has worked great for me too. My new G062 is a 14mm bigger...

    Thank you sir. A true pioneer. - I'm assuming you took off all the magnets when gluing, or did you epoxy around them in place? You dont happen to have a link where you can purchase these 30x15 magnets do you? (worried about breaking them). - Slightly upgraded wiring refers to the OEM wiring...

    Good to hear! If its 24x4 fat tire, its probably about 27" overall diameter, bigger than most 24 tires because of the extra sidewall height. Not at the level of JTK77, but I feel my motor is getting nearly maxed out at this point in the 3-7kw range, and at 72v. Theres really not too much more...

    You have a sweet setup, and lightweight! The G062 comes in 750 and 1000, they are identical as far as I know- except the motor connector. I found a supplier that has the L1019 connector on the 750w versions, and 750w is the USA legal limit, so its the perfect motor for me in the USA. I ride the...

    I ended up going with your venting approach! How has your motor been handling those power levels, any issues? Any issues with debris entering the motor? Did you break the clutch at some point? You said you found the failure point around 4000w, curious what that meant?

    Clean wiring. Its going to be a loooong time until someone out does that setup!

    Ok so G062 running 50a/90a phase, running it hard- Stripped gears and multiple drive/magnet pins within 200 miles. Magnets overheated and all came loose not long after. Finished the job by burning the windings within 1/2 mile of a 25% grade with a already hot motor. That motor is done. New...

    Running the 2/3 nylon 1/3 steel gears. No new noise as of yet. I have something weird going on. Opened the brand new G062 up after running high torque to find the stock nylon gears entirely stripped. Also had a grinding noise, but only at max torque (low/mid rpm) it almost sound as if its...
