Hey everyone!
I'm curious to know what the most efficient RPM range is for brushless motors. I am trying to build a big rock right now, and I want it to run cool on grass with a top speed on packed dirt/pavement of 60+mph. I've done some research, and I've realized that the more watts the motor can produce, the cooler the setup will run as long as the watts are mostly produced by higher voltage and not higher amp draw. I have also read that to run a motor at close to it's max watts, you need to be close to the maximum amount of voltage
In my case I am looking at 2 motors, a TP 4050 2100kv and a Tp 4050 1550kv. I am trying to choose one to run on 6s... the 2100kv will be around 52-53k rpm when it has a maximum of 60k and the 1550kv will be producing somewhere around 38k. Logically speaking, it seems like the 1550kv on 6s would be better, but since the 1550kv has a max volt of 40 it wouldn't be running close to it's maximum watts whereas the 2100kv would be very close to it's maximum watts. Will the 1550kv run hot because it isn't producing a lot of power on 6s, or will the 2100kv run hot because of it's high rpm?
So this puts me in a dilemma trying to figure out which motor to get.
Thank you for all your help,
Have a great day!
