LN-motor FS2812 and FS2306 brushless motors for FPV drones
Commonly, the product name of FPV motors is formed by a group of two numbers. The first one refers to the dimensions of the motor and the second one to the speed of the motor. Brushless motors have two main parts: the rotor with permanent magnets and the stator with copper coils. After learning to decipher the numbers on FPV motors, we will analyze two motors from LN-motor in detail.
The first number has four digits (DDHH) and represents:
- “DD” is the stator’s diameter (or width) measured in millimeters.
- “HH” is the stator’s height in millimeters.
For example, the LN-motor FS2812 has a stator with 28mm diameter and a stator height of 12mm. Bigger motors have larger magnets that are capable of generating more thrust.
The second number is “KV” and represents the number of revolutions per minute (RPM) with no load when a one-volt is applied to the motor’s terminals. Therefore, theoretically,…
