Speed Calculator

Thanks. What I'm trying to understand is this:

For example: A Aveox 1415/2Y has a Rt of 0.022 Ohms and a Io of 1.8, now a 1415/1.5Y has a Rt of 0.010 Ohms and a Io of 2.5. I have tried the 2 motors above with 6S both geared for the same speed and the 1.5Y was always warmer and pulled more AMPs then the 2Y.

You can get two motors from the same series (neu 1515) and run them both on 6s. The lower kv motor would need higher gearing and the higher kv motor will need lower gearing to achieve the same speed. Why will one motor run cooler and longer than the other?

My assumption was that both motors would produce the same amount of watts and therefore the same amount of amps. But if the runtime on both motors is different, one will actually pull more amps&watts...

Cheers BrianG!

Where can I find the Keda Model 1900kv motor ? When picking motor, I thought it would put in the resistance as well but it doesnt. also about that 'enter current draw' should i put in 3.9A or 55A? under the ?-sign is says 'motor current draw'. even my medusa motor wouldnt draw 200a ? it continue about weight of truck.. i dont understand this.

i was hoping it put in the right specs of motors in the right field(s).

Section two, in 'gear diameter calculator' would be nice to have 2 or 3 of that next to eachother(sidebyside) so one can compare different gear sets.

brilliant work again!
