Polyfunctional electromechanical energy transformers for technological purposes

Abstract

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.

“…The use of electromechanical converters as the links in the technological chain for the processing of bulk and viscous materials is among the current trends in the field of scientific research of the 21 st century. A promising class of Polyfunctional Electromechanical Energy Converters (PEEC), designed for the direct technological processes implementation, is distinguished by an enhanced concentration of functional and energy properties, as well as the almost complete use of electric energy coming from the electrical power network (Zablodskiy, Plyugin, & Gritsyuk, 2014;Zablodskiy, Plyugin, & Gritsyuk, 2016).…”

Complex Design Tools for Improvement of Electromechanical Systems With Induction Motors

“…In foreign literature, mechatronics is a definition that often combines both of the above terms. Another direction in the science development based on the integrated design principles, is the design of multifunctional induction motors [12] (for example, the simultaneous realization of mechanical work to move liquid or bulk media and their heating). In this case, the synergistic effect is in useful use of losses in induction motors and intensification of their cooling [13].…”
