The paper deals with the problem of electromagnetic field analysis for linear, cylindrical and spherical electromechanical converters at synchronous state of work. There are considered synchronous motor with windings on moving part (rotor, carriage) and with permanent magnets thereon. The electromagnetic field is determined analytically with the help of separation method proposed for each problem. The boundary conditions are formulated for electromechanical converters linear, cylindrical and spherically shaped. The results obtained can be used as benchmark for electromagnetic field numerical analysis and force/torque calculations.
The paper deals with the problem of force and torque calculation for linear, cylindrical and spherical electromechanical converter. The electromagnetic ﬁeld is determined analytically with the help of separation method for each problem. The results obtained can be used as test tasks for electromagnetic ﬁeld, force and torque numerical calculations. The analytical relations for torque and forces are also convenient for analysis of material parameters inﬂuence on electromechanical converter work.
