Hello!
I have been reading this thread for a few days and now I’m 80% confident in the specs of my build but I need some advice to choose the right motor and gear ratio. I am 240lbs but I’m in the process of losing weight so hopefully in a few months I will go down to about 200-210. I’m planning to order everything from @torqueboards and esk8.de
Updated plan:
Single motor setup with torqueboards’ kit with 83mm wheels
Single motor at your weight I’d go with a 6374 motor instead. If you want to only go 30-35km/h drop the gearing to 14/36 for increased torque. Make sure you’re using at least 12mm pulleys and belts.
Dexter is good man at torqueboards im a big bones guy mysefl at 200 lbs and recently finished my first build , i haven ridden a different board besides mine but im loving it its been very reliable so far i would say a turnigy sk3 6374 149kv would be a better choice considering the load (240 lbs) im running a single 149kv and this motoris a beast another thing you hae to consider is top speed you are trying to achieve, as with a higher kv motor u can reach higher speeds but less needed torque for our case, wich can be remedy with the righ gearing i did the calculations for my build when i was building it and i think the top speed was 21 or 22 mph wich at first i was like i want to go faster but believe me 20 mph on a longboard its hella fast and also when i was testing my board for the first time i got up to 20 mph really quick and ran out of balls i had a lot of throthle and momentum left i say judging on how much throtle and how quick this thing is close to 30 mph
Well, then I just have to find a source which has the 149kv motor in stock I can’t find it anywhere but I agree with you, I don’t want to go faster than 20mph and more torque would be better for me.
But when I do the calculation the rpm goes very low. It should be around 7-8000 at 3.6 volts, right? @Pablo_702
on the i dont remeber how to manually do the calculations its in the forum somewhere but yes i remember when i was doing my homework the the erpm were crazy low, have you thought about going 12s? it will be more powerfull and less heat, are u planning to use a vesc?
see thats what i got it says 22.87 weighted but im sure its more like the top speed of 28.58 mph maybe if @Michaelinvegas wants to test its final speed hes more than welcome to gps it for science of course
Hm, as this will be my first build I don’t know what to expect with a 149kv motor at low rpm. Even with a 12s battery it works way below the recommended 8-9000 rpm. What effect does it have on the vesc, battery or the motor? and how important is it to reach the recommended rpm?
Hi
I am ± 200lbs and use the 6374 170KV motor on 8S.
15T x 44T gearing and 97mm wheels.
Speed is fine for me and it goes up all the hills in my area without a problem.
VESC did get to warm though on steep hills so now use a ESC very similar to TB 12S ESC.
Actually prefer this board to my dual 6355 240KV 8S board with VESCs.
Looks like I will able to source almost everything, the only part missing is a custom 10S3P - 18650 battery pack. Is there anyone in europe who would build it to fit this layout that I have planned here?:
