Several important parameters of brushless motors:
KV value: The running speed of the motor. The larger the value, the greater the motor speed. Motor speed = KV value * working voltage.
No-load current: The operating current of the motor without load under the specified voltage.
Phase-to-phase resistance: The resistance value between the two phase ends after the motor is connected.
Torque: The driving torque generated by the rotor in the motor that can drive the mechanical load.
Slot pole structure: (N: number of slots, P: number of poles) Common internal rotor brushless motor structures of models include 3N2P, 6N4P, 6N8P, 9N8P, 9N10P, 9N12P, 12N10P, 12N14P, 12N16P, 18N16P, 18N20P, 27N24P, 27N30P , 36N32P, 36N40P (commonly used in inductive motors); Common models of external rotor brushless motor structures include 9N6P, 9N12P, 12N8P, 12N10P, 12N14P, 18N16P, and 24N20P.
In the model the external rotor motors are all fractional slot motors:
1. N must be a multiple of 3, and P must be an even number (magnets are in pairs);
2. The smaller P is, the higher the maximum speed is;
3. If N is larger than P, the relative speed will be higher;
4. The N value is the same, the larger P, the stronger the torque;
5. N and P are not divisible.
