My motors are 6.5T rather than 6T to it helps a little, but ive actually never melted phase wires with the L1019. Even with the vents, the windings themselves typically short before the phase wires do. Then again the venting might help the phase wires too, keeping the internal portion of the...

I ended up doing MONSTER vent holes (2-3x as large as the previous/JTK's) just for testing to see if it brings temps down significantly or not. I'm also going to try ferrofluid, I know its "stupid" for geared motors, specifically vented geared motors offroad, but going to give it a shot for...

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...

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...

"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...

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.

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...

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...

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...

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...

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...

Your information is invaluable- thank you. When it got the hottest around 125c (max temp), do you have any idea how hot the motor case was around this time or just after this time- were you able to put your hand on it for ~1 second at this temp? On a long ride (continuous) 20-30mph it seems...
