Motor kV ratings being off, how much is tolerable?

[Gamer43]

Manufacturers specify a ± 10% tolerance on the Kv rating.
Here’s how to calculate the Kv from the measured flux linkage

Wiki: What Motor Parameters Mean

Quick run down on what the hell motor parameters mean during detection, and how you can use them to help in your calculations Resistance: The line to neutral (from ESC terminal to center tap of motor windings) resistance of each phase of the motor. This determines how much heat per ampere is dissipated inside the motor. The equation is approximately: For FOC: [image] For BLDC it’s : [image] Where I is motor current, R is phase resistance. This does not include things like bearing losses, …
