What is KV?
kv : means the motor's rpm(speed) per voltage in no-load condition.
The speed of the motor is inversely related to the number of poles in the rotor. The relationship is explained by the following formula:
Where:
Ns = synchronous speed
f = frequency of three-phase power supply
And #p = the number of poles
How to Calculate Motor Poles?
Since the number of poles is equal to the number of permanent magnets in the rotor, the simplest way to determine the number of poles is to count the magnets manually. This is possible if you can see into your motor or if you are able to remove the outer casing. If you are unable to remove the casing this can be a challenging task as the magnets can be quite small and numerous.
