WebJun 17, 2024 · BLDC drives. Due to its slot/pole combination, the studied claw-pole motor inherently suffers from particularly high cogging. torque and hence output torque ripple. The proposed cogging. WebB. Selection of Slot number for a given number of poles The number of poles in a permanent magnet Brushless DC motors must be even values for any number of slots. But one cannot assign any number of slots for the desired value of poles; there is a certain combination of slots and poles, which lead to efficient torque production.
