kV of an electric motor?
 

Hello,
I was wondering what the difference of a 4100kV, 5600kV, and 5800kV motor was?

Thanks

300:

The 5800 kv motor is 1700 kv more than the 4100. He he he

basically the way i understand it. KV has to do with the amount of RPMs per volt of power. so a 4100kV motor would spin 4100rpm per volt from the battery pack. That's how I understand it.

Ah, but there's more...

you also need Kt, or the torque per volt...+ other parameters too.

Basically, you can have many motors with the same Kv, but they will not all have the same torque. You'll still need to match the power (watts) that you want for your application with the appropriate motor size (rated power of the motor).

Gear boxes will allow a lot of fine tuning but most find it easier to change props to work with what they already bought.

For most speed applications, direct drive is the preferred method.

For HIGH POWER setups, go with as high a voltage as you can to keep the amps low, things stay cooler and less chance of leaving a smoke trail[:@]

That's true. We all know that you want to keep the smoke on the inside. Once you let the smoke out of electrical components, they don't ever work the same any more.
