Abstract :
The model of a magnetic field inside the permanent magnet spherical stepper motor is developed using the integral equation method (IEM), and discrete expressions for field distribution are also derived. The results of the IEM and finite-element method show the effectiveness and advantages of IEM for the magnetic field computation on the permanent magnetic spherical stepper motor
