You'll need a support bearing on the other end of the motor shaft if you want to run more power. Without it you're relying entirely on the bearing in the motor to resist the sideways force on the shaft caused by tension in the chain. That's a significant lever arm

@@NGC1433 No, you still want a support shaft. Brushless motors especially pancake motors were not designed for having sideways force on the shaft at all. They are meant to spin balanced props. He would need an inruner motor if he plans to run without a support bearing. Even then it's always better to have one as the petrol engine has a gearbox with a fat shaft real close to the casing which supports all the side force. The shafts are strong ad designed for that application. The bottom line is he needs bearing support if he's going to run any serious power and wants it to last for a while.

Great idea and explanation

Previous Electric Go-Kart mechanic here: First issue I see is as you pointed out, the ESC has no idea where the motor is in its rotation. That black wire coming off the motor is the encoder signal that the ESC uses to determine the position of the motor. We had issues if the encoder became out of sync or out of calibration or even just outright die, the motor would do funny things like make noise or stutter in it's rotation. This is probably why the first controller you used did not work, it was looking for that signal and couldn't do much without it. Our karts used a motor controller/inverter known as a Sevcon. They are about $300-$500 USD online for the models we had and our karts ran at a nominal 48v and max amperage of 100 amps. 100 amps was programmed as it was just below the max 120 amp output of the 16 nominal 3.2v LiFePo4 batteries in series to create the 48v. There is an alternative that has become popular that the kart manufacturer switched to known as Curtis controllers. Both controllers are pretty well-designed and we had little issues with the Sevcons, we did have one Sevcon that the battery terminal melted but that I had determined it was due to a loose/bad connection. I left the company shortly after they got a new fleet of karts that used the Curtis system so I can't speak to the their long term use but a lot of online shops that sold motor kits, included a Curtis controller. The only problem with using one of these controllers is the programming cable or software was the expensive part. The programming cord for the Sevcon alone was about $1000 with free software. If you did decide to use one of these, the only issue I can see if you used these is that they are not consumer friendly and require some knowledge of programming the controller to work properly with the motor. I never had to do that, the controllers came pre-programmed and we had a backup file to write to the controller if we ever had to. Though I will mention both of them had a calibration tool for the encoder that would walk you through how to calibrate the encoder so that it was in sync. The Sevcon was a more manual process that you had to take "logs" of the data and put it into the software and it would tell you what to set the encoder to and the Curtis had a one click button and it would go through the calibration process automatically without user input. If you were to pick one, I'd suggest the Curtis of the two. There is another controller that I can't remember the name of but I recall Colin Furze used one on his drift trike and that seemed a lot more user friendly and didn't require expensive software or programming cables. Gear ratio should not be an issue here as our karts had a ratio of 3.636 and had no issue of spinning the tires out from a stand still and I'd assume the weight of the karts aren't too far off the weight of your ATV. It comes down to programming the controller to how much power and torque it uses to get up to speed. If you would like to ask any questions, I'd love to help as much as I can. But I am no expert of the programming side, only the few settings I would have to go in and change like max RPM, throttle input, or calibrating the motor encoder. I'm pretty sure I still have the PDF files of the parts somewhere and could get you exact part numbers of various things like the TPS sensor, batteries, etc. EDIT: I do have those PDFs :)

Thank you for your help here. I just gave him some gems of truth I learned along the way as well. I am wondering about the gear ratio as well. Not so much that it is a problem but that all the motors I had which were sensored traction motors designed to run at low rpm all had very large windings. By large I mean the winding wire was 14-16 gauge single strand. I noticed his motor has fine strand wire and I'm wondering if it is designed to operate at much higher RPM. I hope we can help him to accomplish this with less challenges than you and I have had along the way. One of the easy to program controllers is the Alltrax brand and the Kelly controllers are also good. I have used 3 of the 4 with good success.

I’ll be honest though, still love the video, not criticizing as I would have done the exact same thing just to get it moving around while I waited for the big boy esc to show up. The only difference I would have made if I may suggest, is #1, run a dc to dc buck converter to power the water pump off the main batteries, use different batteries in general. I build custom lithium batteries for everything from my 165KW home solar battery, to small desktop projects. By using the lipo cells without either a bms, no temperature monitoring, no balancing, or under voltage protection, it’s potentially dangerous. I’m sure the esc has a low voltage cutoff, just kind of sketchy to rely solely on that to keep the batteries within spec between voltage, overall current draw, and temperature. If interested, I’ll make some suggestions for some either modifications to your current lipos, or how to build an even bigger battery cheaply that’s safe, reliable, and can handle the power demands easily

I'd say first change the gear ratio. That will yield the biggest results and should limit how much current is needed, right? My guess is that the motor can spin much faster than ever needed, so changig gear ratio will not have any real downsides.

@@fluffigverbimmelt I'm not sure how much heat is generated that can be taken care of using the water cooling system, but dumping it into the chassis is probably not going to do it for two reasons first of all the chassis is made of steel which has pretty poor heat conduction. And second is that the chassis is made of round tubing. That means there's not much surface area to radiate or cool down through convection. And cool down it needs. Just because there's something like 50 pounds of steel to heat up doesn't mean you can just sink the heat into it. That would just accumulate the heat. No the water has to be cooled down. A 240mm PC radiator would probably perform decent but bigger is in this case better. But it shouldn't be to hard to find an old MC radiator which should provide ample cooling if it's needed. Now the expansion tank doesn't need to be all that big. All it's supposed to take care of is the difference in water volume due to thermal expansion. There's really no need to have the water flow through it if you got an inline pump. Just put the expansion tank somewhere high and connect it to the cooling loop at the highest spot using a T-connector and you're done.

I came here to say this too, its literally made for it

You need to use a VESC for this kind of use case instead of a regular ESC. VERY IMPORTANT! PLEASE research VESCs before buying any new ESC. When using this size of motors, the ESC/VESC has to be specialy calibrated to that particular Motor. Otherwise, the whole system will burn out at some point because of the high amp draw and voltage. You can do that with VESC, and not with ESC. a hobby ESC is made to output as many amps as needed to do whatever the PWM signal from the radio tells it to do. Even though it says 300A. That doesn't mean that it will cut or limit power at 300A draw to save itself from being damaged. with a VESC you can program an Amp limit draw, and it will adjust the voltage accordingly. Kinda like when you change lipo batteries. This will also save the ESC from amp draw spikes when starting up or doing hard accelerations. This is the key to not constantly burn out ESCs like you seem to do quite often :) Use the sotware called "VESC tool" program the VESC

Look up Fardriver or Kelly controller, they make "real" motor controllers (made for electric vehicles) which don't go up in flames as they have over current protection. The controllers are actually not more expensive than high power RC controllers, they are around 3000-5000 SEK. They are more tricky to set up, but they are sensored, have FOC and are just better and more reliable in every regard

Cool project. A number of years ago I modified a Kawasaki kz305 to electric with a Curtis controller and motor combo good for up to 72 volts and built my own battery from 18650 cells. It was fun but the range was limiting so I got an old quad and did basically what you did. I also hit the lack of torque you saw so I added a jack shaft to give me better gearing. (I could not go bigger on the back sprocket because I would have been hitting the ground and other parts of the sprocket grew larger. Now I can pull garden carts and I added a hitch ball on the nose and I move my homebuilt teardrop camper around with the quad. Nice little workhorse.

Max power of an BDLC occurs generally around 50% of no load RPM (peak efficiency at 80%). If you run the motors at say 20% of that you're not going to get anywhere close to the max power output (except heat).

For context in this case; For simplicity assume it's 100kv motor. No load RPM at 48v = 4800 rpm. Peak power at 2400 rpm or 40 rps . Gear ratio = 3. Rear axle will rotate 13 rps. Assume tire diameter of 0.5 m => ideal speed 21 m/s = 75 km/h. Discounting all losses friction, wind, resistance, rotational inertia. People often forget about the wheel diameter and just focus on gears (it's a 0.5 m wide gear!). A ATV tire is 5 times larger than a gocart tyre, can't size the gear ratio similarly. A proper gear ratio (10?) is better to focus on instead of a larger ESC since a lot of power with this design will just go to heat. Sure lower top speed (35 km/h?) but MUCH healthier for the system and range.

Awesome! That motor is insane! The problem with this project is cost. As you now know the ability of the controller to deliver ... say 500 Amps at 100 Volts is amazing. What it can't do is deliver 1000, or even 500 amps at 24 volts for 30 seconds. Once the HUGE investment in a battery that can actually deliver 500 amps at 100 volts is made the motor and controller will throw you forward so quickly it will only need to make that high amperage for a few seconds. And you will need to hold on tight. Be very careful playing with these current levels. You are dealing with more electricity than I use to weld 1/2-inch plate steel. You know what a MOSFET is, and now you know why we call them Metal Oxide Fire & Smoke Emitting Transistors instead of Metal Oxide Semiconductor Field Effect Transistors. P.S. You are not the only one to learn the hard way ... my collection of catastrophic fire controllers is quite impressive ... until you calculate the $$$.

I have experience building various electric vehicles and what I know is the gear ratio needs to be between 9 to 1 and 10 to 1 to the rear wheel from the motor. You need more reduction simply put.

Use a VESC for speed control. It has FOC control and current limiting which make it suitable for moving people around. VESC is also much cheaper than the speed controllers you are looking at. You can use gokart sprockets to get enough reduction. Use something bigger than #25 chain like #219.

Hello! You vitally need a step-down gearbox for this electric motor. The brushless electric motor has sufficiently high revolutions of its rated power. For its implementation, large revolutions are needed, which a direct drive to the sprocket and chain will not allow. You need a step-down gearbox with a ratio of at least 1 to 5, but it is better of course to calculate the optimal revolutions required by your electric motor. At the same time, the load on the motor control controller will also decrease and it will heat up less, as the operating current will drop. Good luck with the project!

Amazing dude! I enjoyed watching the whole video and waiting for pt2. Now i have to make one of this!

Good info. To fix your starting torque problem, you probably need rotor position feedback sent to your controller so it knows what firing angle to apply to the 3-phase motor windings, since your rotor consists of permanent magnets. Be careful not to over current the motor windings and demagnetize the rotor. It should have very good starting torque when integrated properly. Read the motor specs.

Great project. Waiting for part 2.

Everyone is yelling about the gear ratio… honestly that is just personal preference about how fast you want it to go and the torque you want to get. The real problem here was that he didn’t support the motor sprocket at all - and it hung out so far from the motor. That’s why the chain slipped at 9:50, you can hear it.

That hose sound was so good

great project! looking forward to next episode. One thing: between the motor mount and the sprocket you have a huge moment arm. as soon as you use some power/torque, the motor bearings are gonna suffer. maybe stabilize the shaft on the opposite side of the sprocket with a bearing. good luck!

It turned out too cool. Congratulations.👏👏👏

I’m looking forward to part two and all of the issues you run into because I am also trying to do the same project

great project, looks fun!

Fantastic start, dude! 😃 Looking forward to see more about the project! Stay safe there with your family! 🖖😊
