Polyfunctional electromechanical energy transformers with a ferromagnetic rotor are considered that allow full use of dissipative energy and structural, functional, and thermal integration. The combination in one machine of several technological functions is a feature of such devices. The rotor is cooled with raw material, which is processed. Air and low-melting materials with high thermal capacity and latent melting heat can act as an additional coolant. It is shown that almost all the conditional loss of active power comes from one of the components of net power, this being is heat power, which is used in the technological process. An implementation is presented of the principle of self-regulation in the division of electromagnetic power into two components of the net power: mechanical power flow and heat power. A gearless provision is discussed of low rotation speed and multiple enhancement of transformer torque based on the use of the interaction of direct and reverse fields of master and slave modules, changing the direction of rotation of the field of the slave module and duration of its action. Reverse moment is positive and leads to increased flatness of mechanical characteristics and, consequently, to increased instability of the transformer under load. The delay time of switching on the braking module needs to be chosen on the basis of the necessity of achieving a necessary result of torque of the transformer.

Purpose. To develop the theoretical basis of electrical machines object-oriented design, mathematical models and software to improve their design synthesis, analysis and optimization. Methodology. We have applied object-oriented design theory in electric machines optimal design and mathematical modelling of electromagnetic transients and electromagnetic field distribution. We have correlated the simulated results with the experimental data obtained by means of the double-stator screw dryer with an external solid rotor, brushless turbo-generator exciter and induction motor with squirrel cage rotor. Results. We have developed object-oriented design methodology, transient mathematical modelling and electromagnetic field equations templates for cylindrical electrical machines, improved and remade Cartesian product and genetic optimization algorithms. This allows to develop electrical machines classifications models, included not only structure development but also parallel synthesis of mathematical models and design software, to improve electric machines efficiency and technical performance. Originality. For the first time, we have applied a new way of design and modelling of electrical machines, which is based on the basic concepts of the objectoriented analysis. For the first time is suggested to use a single class template for structural and system organization of electrical machines, invariant to their specific variety. Practical value. We have manufactured screw dryer for coil dust drying and mixing based on the performed object-oriented theory. We have developed object-oriented software for design and optimization of induction motor with squirrel cage rotor of AIR series and brushless turbo-generator exciter. The experimental studies have confirmed the adequacy of the developed object-oriented design methodology. References 12, figures 2.
