Hey guys, I’ve just started to transform my foilboard. And was looking for a motor.
But it’s been quite overwhelming going through all the threads on this forum. People are talking about different motors, but all seems to be not sure whether their motor is sufficient or not, whether it’s cost saving enough.
After days of searching, here’s some of my humble opinion on what kind of motor we should be looking for, what critia, and how should we navigate to the ideal motor.
We are all here to DIY, so cost saving is one of the priorities. That is, we should be looking for the cheapest motor that is sufficient of our mission. That is we don’t need an expensive super motor. The motor should have parameters that are ‘just enough’.
Sufficient parameters to power the hydrofoil.
motor parameters: (help me priortize)
c. output Power
d. Voltage rage (works with the most commonly used 12S)
e. Amp at work (would like to keep it low for safety reason)
f. KV (almost equivalent with RPM, for given Voltage at 12S ?? )
g. dimension (fits the Al tube, natural water cooling)
to navigate to the right motor parameter, we need to think about this sport itself.
a. how much Thrust (in Newtons?) do we need at launching stage for person of different weight (say 100kg)
b. how much Thrust (in Newtons?) do we need in cruising for different weight (say 100kg)
to find the relation between Thrust and Motor Parameters (RPM, torque, Power), we should look at the parameter of the propeller. (seems unavailable?)
That’s what I think so far… But It seems I am stucking at finding the thrust…
Help me, forum.
