abstract = "The magnetic field modeling of the PM-pole rotor is presented. According to the magnetic characteristics of the three regions of the rotor space, Laplace{\textquoteright}s equations of magnetic scalar potential are derived. By using the boundary conditions in between neighboring regions as well as the spherical harmonic expansion of radial component of the residual magnetization vector, coefficients in the general solution of magnetic scalar potential are determined. The magnetic field flux density of the PM rotor is formulated analytically by taking the gradient of the scalar potential. The derived analytical magnetic field model can be used to formulate the torque output of the spherical actuator.",
