Build help with size of belt


#1

Okay so I am gathering parts for my build I want to order the enertion motor mount and the TB 16mm 36mm flywheel gearing I have a 6374 190kv motor on its way how do i know which size belt to get 12mm wide but don’t know the size of the belt. Any help would be appreciated.


#2

You will need 265mm htd5 belts.


#3

Thank you @flatspot


#4

Also with a 6374 190kv motor which would be better all around 13 tooth or 16 tooth with a. 36tooth drive wheel? I’m 225lbs if that matters.


#5

Depends on how fast you want to go. I would start with 13 which might require a smaller belt. What size wheels? My board does almost 30mph on 80mm Kegels w/ 14:36 drive. 16:36 will be crazy fast.

You can play around with some numbers there:

To find out what speeds you can expect for different pulley sizes.


#7

I have 90mm flywheel clones


#8

How many cells is are you planning for battery?


#9

I was thinking 10 its my first board by no mean do I care about speed. Is that overkill?


#10

More cells mean more voltage and less amperage. I say the more voltage the merrier, because amperage is what causes most problems.

On 90mm wheels and 10S I would go 13 tooth drive especially if this is your first go.


#11

That’s partially true. If you have 10 cells and you put all 10 in series (end to end) then you’d get a higher voltage, but fewer amps. If put 5 cells in series and 2 in parallel, so you’d still have 10 cells total, but double the current and half the voltage.

Basically I’d choose your battery voltage based on the motor (or vice-versa), and then chose the number of those in parallel based on how many amps you plan on drawing and how long/far you want to ride.


#12

What kind of range would you expect out of a 10s 5000mah set up 25mph is top speed I would like to go


#13

It all depends on conditions. My board on 12S 5000mAh lipos w/ 6374 gets about 9 miles stop and go averaging about 18mph. Not sure if that helps at all.


#14

So I would be goof running say 2 5000mah 5s lipos in series with 190kv 6374 mono drive and expect 20mph and say 7 mile range?
