Abstract :
When the claw-poled stepping motor is rotated at high speed, the torque remarkably deteriorates because of the eddy current generating in the stator core. In this paper, the influence of the stator core materials on the dynamic characteristics of a claw-poled stepping motor is evaluated using the 3-D finite element method. The validity of the calculated results is clarified through the comparison with the measured ones.
