Abstract :
This paper analyzes static torque characteristics of a permanent magnet type stepping motor with claw poles. The analysis of this motor is a truly three-dimensional problem, and thus is performed by using three-dimensional finite element method with edge elements. We clarify detent torque characteristics by changing the magnetic situation in permanent magnets and by changing the shape of stator teeth
