# Horsepower

Measure of a Motors power.

$HP=5252Torque∗RPM $

From this video power = voltage * current power = RPM * torque

So

- voltage <-> RPM, the higher the voltage the higher the RPM
- AHA, where did I see this from? ahh yes, this is what the KV Rating is about: how many RPMs are you getting per volt that you put into it

- current <-> torque
- BUT, you don’t necessarily need a lot of current to get a lot of torque.

Also, $1HP=745.7W$

A motor’s power is constant

- if you increase torque, you gotta decrease speed. You can’t increase both (will result in motor overheating and getting damaged).

So the question is,
