Hi Dear Forum-ers,I am writing in to seek your kind advice on electric motor selection for fuel cell (in my caes, Aeropak).I presume that the RC motors are mostly designed for Lipo or NiCd batteries,…Continue

Calvin Lee replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"Hi! May I understand the relationship of high voltage with slower motor..?
meanwhile, i will check out geared motors and hopefully thats increase my efficiency..!"
Calvin Lee replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"The 200W would be continuous output. The peak output is 600W.
The design comes with an inherent lipo battery attachment to cater to the purging of the fuel cell to remove the generated water. We are in view of using another lipo battery for the…"
Calvin Lee replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"Yes, I reckon that I need good motor and propeller efficiency but I am could not find materials on motor sizing for this application. Thus, I am hoping to gather some good resources or experience from fellow forum-ers..
For the…"

"200W / 7kg is 28W a kilo, low powered efficient gliders can fly on as little as 60W per kilo, 28's going to be pushing it a bit. You'll need a highest quality competition motor with 6:1 (or higher) gearbox and massive propellor to get any…"
Jose Luis Cortes replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"It seems Aeropak is a "pak" with all included, it seems it comes with stack controller, valves and a small lipo battery (1350mAh), seems to be nice product, but very expensive for me."
bGatti replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"motors are rated at RPM per Volt. as you have High voltage, you'll generally want a slower motor; I'd also consider a geared motor to help reduce speed and increase efficiency.
Here is an interesting…"
Ground Loop replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"With the heavy plane and 200W peak output, you might want to consider pairing the fuel cell with a LiPo battery. The idea would be to use the LiPo to supply additional current during peak draws (climb) and then recharge off the fuel cell…"
Jose Luis Cortes replied to Calvin Lee's discussion Fuel Cell (Aeropak) Electric Motor Selection"Hello Ying, you need good controller-motor-propeller efficiency to keep a plane in flight with 200w and 7kg, I think this motor is big, it get maximum efficiency with more than 15A."

I do understand on this. Could you advise which forum would be more applicable for Selection of Motor for Fuel Cell? I will only focus on that. =)
Thank You!

Hi Dear Forum-ers,I am writing in to seek your kind advice on electric motor selection for fuel cell (in my caes, Aeropak).I presume that the RC motors are mostly designed for Lipo or NiCd batteries, which has relatively lower voltage and higher current ouput as compared to fuel cells.For my case, my fuel cell has a continuous output of 20V, 10A and output power of 200W.Some other parameters: The weight of the fuel cell is 2kg and the overall takeoff weight is estimated to be about 7kg.
