The paper outlines new concept of effective and optimal composite structures. For design and manufacturing stages, main issues and possible approaches to solution are presented in several aspects. Main attention is given to describing an automated data processing system for layup planning, which is to be used for preparation to fabrication process.

the method of field weakening, which provides constant power at a constant current, is examined. This method is based on maintaining constant steady-state values for projections of stator current on the longitudinal and transverse axes of a synchronous motor. The projection of stator voltage on the longitudinal axis remains unchanged, but the projection of stator voltage on the transverse axis depends on speed. To assess the effectiveness of this method, a mathematical model of the electric drive was developed with vector control and a field-weakening module. From this model of the working of the electric drive, the mechanical characteristics and dependence of efficiency on the speed of the motor were established using the program Simulink.
