Polyfunctional electromechanical energy transformers for technological purposes

详细

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.
