In addition to the described problem, the paper also deals with the solution of the problems of
minimization of the turn material mass and determination of the turn parameters with
maximum strength at the assigned distance for three cases: the turn wire diameter is assigned;
the turn medium radius is assigned; the voltage of direct current source is assigned.
Relations among geometrical and electrical parameters have been obtained for all these
problems.
It has been demonstrated that the known tendency to increase the heat dissipation from the
surface of electric devices makes it possible not only to improve power characteristics of
these devices, but it also provides the possibility for increase of the range of solutions to
optimization problems.
VI. Conclusions
1. Optimization problems for an electromagnetic system in the form of a one-turn coil
are brought to the problems to find the function extremum of one variable if thermal
processes in the turn are taken into account.
2. Intensification of heat dissipation of electromagnetic systems enables optimization of
their power characteristics due to enlargement of the range of existence of solutions to
respective optimization problems.
