| Summary: | Relevance of the work is caused by the need to develop electromechanical energy converters and drives using new active materials. The main aim of the research is to derive the equation of the electric drive system inductive capacitive type, taking into account the mutual magnetoelectric effect in the active ferroelectromagnet of electromechanical transducer to analyze its electromechanical characteristics. Methods: control mathematical analysis based on classical mathematical model of the generalized electromechanical energy converter. Results. The author has obtained the equations of static electromechanical and mechanical characteristics of the electric drive with induction-capacitive components, ferroelectromagnet as an active material and determined the type of their characteristics. It is shown that in such devices with ferroelectromagnets as an active material magnetoelectric effect occurs. Its influence is manifested in strengthening or weakening of magnetic fields by the electric ones, and vice versa. As its impact can be substantial - up to 30 %, it must be taken into account in calculations. The author proposed to take into account the impact of magneto-electric effect by introducing additional emf arising in inductive windings and capacitive plates of the tanks in the machine rotor. The mathematical model of the motor in the drive of inductive capacitive DC motor with convection capacitive part of conductive type contains classical equations of inductive and capacitive parts, but with additional voltage in both parts arising due to magneto-electric effect. To obtain the mechanical characteristic equations of the engine it was proposed to use the known equations of the generalized machine adding the above mentioned component. |
