    Big difference between 18km hill climb and 18km ride with 1km hill climb. You might be okay then. Even still a 36km round trip is a lot to ask from a 520 w/h battery. You can use the grin sim to help estimate range with your setup but I still am not sure you could make the commute on a battery...

    I would worry less about the discharge and more about the capacity. If you have a 10AH battery for example with a 30a BMS that means it will run full power for 20 minutes. If you are going 30 kmh up this steep hill you are only going to make it 10km before you are out of battery. To add to that...

    45A controller at 48v is 2200w and 60v 45a is 2700w, sounds like we are on the same page. Most kits from CHINA (OEM kits) do not supply 45a controllers with this motor, around 30-35A is as high as they go. I think theres a reason for that. Deep snow, deep sand, steep hills you can definitely...

    I havent ran G062's in a while and have moved on to different motors. My conclusion is its a great motor for low powered setups, but pushing the power limits on this motor just has too many issues. Hard to fit larger phase wires. The windings have limits. No temp sensor OEM. And most importantly...

    I did get several M14 axle G062.750's (6.5T) from Risun Motor. Not sure what their current stock is. If this is important to you I would ask the seller if axle measurements are 10x12 or 10x14 for clarification. I havent looked in like a year, but last time I looked you cannot find L1121 cables...

    Thermistor - yes exactly. Some controllers that have phase speed sensing will still give you a speed readout even without the speed wire, you just wont get the speed readout when OFF the throttle (because its freewheeling). What fails first - It depends. If you run 90+ phase amps (say you run...

    60-75 phase amps I would consider the limit for "safe". You can run more, just when going beyond that number the chance you have motor issues starts to increase. The gears, the parallel key, and the heat itself from the motor, a "warm" motor can overheat and melt the windings in as little as 30...

    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...

    Did Justin do a writeup on this motor, if so I totally missed it, got a link by chance? Good info on the G063- I'll have to take a look at some pics again. The copper fill from the pics that I have seen looked weak, I'll take another look. Laminations- All kinds of damage. Drilling (even with...

    Okay so the verdict on custom winding: No go. I tried 3 different wire sizes, oem ~.5mm, larger .65mm, and much larger .81mm. The larger wires dont wind as well, the OEM sizing seemed to work best. The oem motors are tightly wound, they seem to be wound very well. Atleast with my winding...

    Ok I have a theory. If you use a multimeter on the lowest ohm setting, and you attach one prong to one of the 3 phase wires on your motor cable, and the other prong to your axle, it shouldnt have a reading, it should be an open circuit (no circuit). If you get a resistance reading, it means...

    That looks like some fun riding! Curious what brand 45a controller you are using that is running "well" sensorless?

    Idk man sounds like it may be your controller. I have multiple controllers/batteries/motors so its easy for me to diagnose, I just plug into a different controller for diagnostics. Idk if the JN has temperature protection. I run it internally with no airflow, maxed out, and have never had a...

    I'm still experimenting with sensorless controllers. Some seem to work slightly better than others. But for hardcore offroad riding (rocks/bumps/jumps) they dont seem to work great. From my experience they can cut out at times, sometimes quite frequently. It can even be a safety issue, there...

    Ferrofluid: This made an interesting noise (sounded badass like a supercharger) but as expected within just a couple miles it all flung off. Because its a geared motor spinning at much higher RPM than most DD's it just flung off the magnets and onto the windings and whatever else. Did not work...

    Sweet! And good info- thank you. I'm sure it helps, I left the nylon gears in my brand new motor about 3 weeks ago (after breaking about 4 sets of them) just to give it one last shot at 90 phase amps only- plus they were the nylons with a little bit of steel coming around the sides a bit, the...

    I wanna see how close my watts and torque guess was! Hurry up on that dyno! Yeah 6.5t is only 12 strands. I think 6t has better copper fill? Are you sure yours is 15 strands? Possibly why my windings are going before phases. Also not sure if the venting helps the phase wire temps ever so slightly.

    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...
