your budget will be tight if possible at all especially since shipping to aus is crazy high.
but at least use diy pulley 12mm kit because enertion’s requires truck mod.
running your motor at lower voltage is fine. it will just be slower.
if you can I would say up the budget to get a vesc and 9-12s battery because it is worlds better than the 6s esc.
Strange- calculator says 55km/h when weighted at 80% efficientcy,. btw, made a new thread with a whole lot more newb questions. no pressure, u have allready done a lot for me
thanks
no problem. i’m working on a wiki to help avoid these types of questions so its good to see what people are confused on…
for the calc i think you left the battery at 10s?
16/36 is actually a lower gearing ratio.
1: 36/16 = 2.25
2: 36/14 = 2.57
i guess writing them backwards doesn’t help lol.
so 1 would have higher top speed. 2 would have more torque(acceleration).
range depends on many factors. gearing will only change this by a bit.
it really comes down to how/where you ride. the faster you go the less range. the more hills less range. heavy rider less range. opposites of these give more range.
efficiency - the ratio of the useful work performed by a machine or in a process to the total energy expended or heat taken in.
in english, something like mpg for a car. more efficiency means more range with the same amount of energy.
erpm is the rate the esc is switching the motor phases.
similar to kv of motor. where kv = rpm per volt. but since bldc motors that we use have 14 poles in pairs we multiply kv by 7.
so erpm = kv * 7 * voltage
voltage = 4.2(full charge li ion/lipo) * 6(s in your case).
erpm is really only important with vesc because there is a 60,000 erpm limit. above this causes problems.
this is why as voltage goes up we use lower kv motors.
