Electromechanical converter with anisotropic spherical rotor - Analytical solutions for electromagnetic field, torques and power losses

The paper deals with the problem of electromagnetic field analysis for spherical electromechanical converters, taking into account magnetic anisotropy in analytical way. The electromagnetic field is evaluated analytically with the help of separation method for magnetic vector potential. The electromagnetic torque and power losses are also calculated analytically. The results obtained can be used as test tasks for both electromagnetic field numerical analysis and torque calculation.
