Hello issong,

0 order (0 Hz) means we have DC component in cogging torque.

Could you enter more value in “points per cycle” of cogging torque calculations of input data -> settings -> calculation?

The cogging torque frequency is the LCM (least Common Multiplier) of rotor pole and stator pole number, so we may need a good number for the points per cycle, to present correct cogging torque frequency.
