Spherical electromechanical converter - Electromagnetic field distribution, electromagnetic torque, power losses and power balance

The paper deals with the problem of electromagnetic field analysis for spherical electromechanical converter taking into account its magnetic anisotropy in analytical way. The electromagnetic field is evaluated analytically with the help of the proposed separation method for magnetic vector potential. Power balance, power losses and electromagnetic torque balance are checked over. The results obtained can be used as benchmark for electromagnetic field numerical analyses and they can support design process of electromechanical converter.
