This paper analyzes the static characteristics of a permanent magnet-type stepping motor with claw poles. The analysis of this motor is a truly three-dimensional problem. First, the authors clarify the distribution of magnetic flux density in the motor. Then, they calculate static torque characteristics of the motor and show the good agreement between calculated results and measured data. Moreover, they show the difference of torque characteristics developed by two types of magnetic situation of the permanent magnet
