Greased my front Bafang motor on my Grizzly, much quieter now!
Yeah it can really help to do that once in a while !!
How about "Lucas white lithium grease". I keep hearing white lithium grease is what they put on in factory. The lucas stuff was only $7.99 and figured this will work, but haven't heard about antone using it.
For a more thorough job of cleaning the planetary gears, remove whole assembly and then the individual gears
That grey stuff in the grease is fine aluminum dust from the aluminum gears that the vinyl gears spin around. Aluminum is very soft metal, that's why they can use nylon planetary gears these motors. Totally normal.
interesting, Yeah I wasn't sure if that grease from the axle had got mixed with the white lithium grease and caked up, or what that was. It looked metallic, makes sense!! That stuff was really difficult and tedious to scrape off the nylon gears
You could just use a toothbrush to clean out gear teeth.
thanks kevin that is a good idea, I am planning on giving thoose a better clean at some point and i will try that!!
@@EBikeBuilder_ then clean brush on the rag
Thanks
Clutch needs puller
I like your vids. With my 203mm rotor I dont need to remove the rotor. Also on the cassette side, the newer version of the motors have one large lockring instead of 2 smaller ones. What that means is you dont have to take the cassette off to open the motor. You could probably weld or jb weld the nuts, it makes it way quicker to open when you dont have to take either of those off, its 6 machine screws and a locknut, its open in 2 minutes.
very true, that crossed my mind- with a larger disc rotor, I think at least 180mm, you wouldn't need to take it off. Interesting how the new motors just have one large lockring! I may try the JB weld and see if it holds. Thanks for the insight and that suggestion, also the kind words, i appreciate it!
Let's see a video of it. I gotta see this because yes opening the hub is a pain and time consuming.
@@jamesbronz not sure what you want a video of. If your motor uses 2 small lockrings, you can weld them together or just put spacers (washers) underneath one of the lockrings so that it can be removed without pulling the cassette off (you can fit a wrench on it, instead of needing to move the cassette to fit a wrench to get to the bottom lockring). Opens up in like 3 minutes.
How many watts do you run through this motor? I have a Hangtai/Hentach geared hub motor that comes with the wired freedom/cruiser (peak at 2300 watts) and p51 ebikes. I plan on running 3500-4k watts through it @ 60v. The exterior gets up to 150f when running this amount of power under stress testing. Do you think this will be okay? It has steel-reinforced gears. I hear these motors could peak at 300f? Planning on using field weakening to make sure it gets up to just over 40mph on flat ground.
its 1000 nominal, Grin Tech seems to suggest 2000 peak. If you are going into wind, up a hill, want to go fast down a hill, you can do more, like 2500w to 3500w, but there are diminishing returns- 2500w won't feel much different than 2000w, etc. I have done 4kw in the motor before, but if i am doing a lot of power- its only for a few seconds. I think those Hengtai motors are probably very similar, they are a bigger diameter and probably have larger/more magnets. The thermals might be slightly different due to the casing of the motor and etc. The main thing with these geared hubs is they have low efficiency below a certain speed, depending on the motor windings, my g62 has low efficiency until about 15mph. So you just want to avoid crawling up hills very slow and using lots of current when the efficiency is low, that wasted energy turns into heat. So for example dont give it 4kw from a stop, ease the throttle till you get moving. I haven't measured the temps of mine but i have had the motor casing get quite hot before where i could barely hold my hand on it for more than a couple seconds. I am surprised that nothing was damaged because I also rode it in sloppy wisconsin winters.
@@EBikeBuilder_ Makes sense! Thank you for the comprehensive response!
Are you using Phaserunner and Cycle Analyst on that Wired? If yes then you can get a potentiometer from Grin plug it into Cycle Analyst and program to adjust the amount of amperage you need by just turning the knob. I don't use pedal assist numbers. I can set how low or high of an amperage range then instantaneously adjust the amperage I want.
@@maximumchargeEV to answer your question though- I cant say for sure about the Wired Ebike motor from Hengtai, I just wanted to help by sharing my experience with my motor. which is probably very similar to that one!! I don't know about the metal / nylon hybrid gears that they claim to use in the Wired etc. But that motor on the Wire3d seems just as good, if not better. But if any component of the motor is not up to the heat. it might have issues. So it depends on their manufacturing and whatnot. Only one way to find OUt Lol.
@@maximumchargeEV keep in mind these motors are like 80% something efficiency even when spinning at ideal rpms, So if you are doing 4kw There is 1kw of energy turning into heat, thats like a space heater on high, so think of it light that while you are riding it down the road at 4kw - it will be getting HOT , FAST, dont over do it
Don't use synthetic that's metal on metal you need lithium and it's white lithium grease you need
Looks like they sold you a 750w motor, lol. Curious what the outside says. I just bought this motor from Accolmile (G062 1000W), it was a kit with a 30a controller and T1 Touch display. I've got 2 14ah 48v Aventon batteries that I'm going to wire in parallel with a blender. What speeds do you think I can get with that? Also, my bike already has a 750-1000w Shengyi motor on it with an L1019 connector - would I be able to just plug that in an keep the Bafang as a spare?
Its a g62 from greenbikekit. What makes you think its a 750? I think the clutch assembly is the same for both the g62.750 and g62.1000 , is why that particular piece had the 750 on it. The motor cable is l1019 and much thicker than my g60 750w
Outside is rm g062.1000.dc (6)
@@EBikeBuilder_ When a motor has a different motors part stamped on it It's just a red flag to me. They can put an L1019 cable on a 750w motor. Hopefully your right. Did you read my question about the Shengyi motor?
@@davidlorin1379 hey , sorry unless you create a whole new comment, youtube tends to hide the replies - to - replies type stuff. i never get any notification. But I remembered. I have a G62 from grin i am going to open and compare to it. I am assuming grin got their shipment from bafang, and hopefully didnt get punked with 750w motors Lol and that should be a 1000w for sure. It also has a temp sensor or at least its supposed to. I am not sure about the shengyi i haven't opened one of those up yet. My aventon sinch was advertised as 500w / 750w peak but it had a 21 amp controller and did about 1100w was the limit on the BMS. I am assuming you could put any of these motors on 72v and do a good 2000w, sabvoton 72 45 is a 45 amp controller thats about ~ 150$. With this sketchy questionable G62 that might be 750w from greenbikekit, i have always ran it like I thought it was a g62.1000 .. so lots of 2000w continuous for a good stretch commuting and what not. IDK. If iots a 750w and they upgraded the motor cable I guess whatever it still goes like 42 mph on 72v
Mine is the same motor but 250watt 36v im trying to upgrade but cannot find one with cable coming out the opposite side to the gears
BAFANG RM.G062.1000.DC (6) is the one i used for me rear motor. It has M12 axle flats and a L1019 motor cable. Which is the best cable to get as far as I’m aware. Bafang has newer motors the g063 that comes in an M14 axle and a red motor cable connector with 11 pins that’s made by julet. But apparently some people say the phase wires are not as thick and the g62 with l1019 connector and thicker phase wires is best. The g62 has cable coming out by the disc brake rotor.
@@EBikeBuilder_ Wow thank you, sir, very helpful not sure where I can find such a rear hub but I'll definitely look around I found this my question is will this motor fit into my 250w hub, i mean just swap the internal motor over not the whole thing.2023 Bafang 190mm version 48V750W rear freewheel hub motor with disc brake for fat bike Motor electric bike Kit found on Aliexpress.cable comes out of the left and it looks just like my own so any advice much appreciated
Should be the same on a Kepler motor. 63 instead of 62 numbered.
thanks for that info kevin !! i have seen the G63 rear hubs and also G61 front hubs on ali express. with 5.5 windings that probably go close to 50mph on 72v
dont be so sparing with the grease.....aint no such thing as too much on those motors
That's Generally my strategy in Life. But it seemed like extra grease sheds off the planetary gears and clumps up on the clutch assembly and the hub shell. I left some extra in there. But it seemed like too much could be a bad thing, if its clumped up a crevice of the motor where its never going to see the gears again.
@@EBikeBuilder_ get some mobil grease #28 the red synthetic stuff and ya wont have to mess with it for a long time
