Rpm vs mph???
 

I hv this 2 motors n want to know what's the diff between these 2 set up?

I am using 6s lipo n on a CRT.

1.neu-1515/3d with 16/50spur speed 37mph, 30192 rpm

2.medusa 1600kv with 13/50spur speed 35.41mph, 35520 rpm

i am confused do we measure by speed or rpm? so which setup is faster? less rpm means less torque?

Rpm directly corrolates to speed.but these two cannot be directly compared because they use different kv motors and differenent gearings.

Torque is based on Kt or oz/in per amp of power. In most cases Kt and Kv are directly related..


*in most cases*
-A motor with a higher Kv will have a lower kt

-a motor with a lower kv will have a higher kt.


So running a lower kv motor (with a higher kt) on higher voltage results in a torqueier power system.


hope this helped

Hey thx now I know:)

I wouldn't say that, a lower kv. motor will draw less current to do the same thing (torque), a higher kv. motor WILL draw more current to do the same thing as well. They will both be equally powerful and same torque levels for a given max rpm setup.(well, the higher voltage will be SLIGHTLY more powerful :smile: ) The only difference really is running temps, they will always be lower when you increase voltage and lower the kv. value.
