Tips: How Much RPM Motor is Required for Drones?

The brushless drone motor used in a drone is defined by "KV". The general rule of thumb for finding the speed of a brushless motor at zero loads is RPM = KV * Volt. KV = the rating of the brushless motor & Volt = the total potential difference of the lithium polymer battery.

A wide variety of brushless motors are used in drones, ranging from 40KV to 1900KV. Quadcopters and triacopters use higher KV motors, and octocopters use lower KV motors. The lower KV motors run at slower RPMs, but they can generate more thrust by handling larger propellers. The higher KV is better suited to handle smaller propellers. As a result, low KV brushless motors can produce more thrust even at low speeds. They are also more expensive than higher KV motors.

The volts of a lithium polymer battery now depend on the "number of cells". (1 cell = 3.7 V) Typically, drones use 3 to 6 Li-Po cells. Therefore, the volts are between 11.1 V and 22.2 V. Now, you can calculate the speed (RPM) of the drone. The speed (RPM) of the motor ranges from 1000 to 20,000.
