“…In the article [9], a mathematical model of a highspeed drive based on an IDM and a bistable mechanism was developed, which includes the equation of the electromagnetic field of an electric circuit and the equation of motion. The model correctly describes physical processes and can be used to develop and study the design of highspeed wires.…”

Purpose. Development and analysis of the operation of an electrical circuit for controlling a 700 W direct current electric motor using a contactor on IGBT transistors for operation in diesel locomotives. Methodology. Analytical and computational methods for developing and analyzing the operation of an electrical circuit using a contactor on IGBT transistors. Findings. An electrical circuit for controlling a 700 W DC motor using IGBT transistors was developed. The circuit allows you to replace electromagnetic contactors with IGBT transistors to improve the technical characteristics and performance of the electric motor. The use of IGBT transistors allows you to avoid burning of contact groups in comparison with an electromagnetic contactor. A graphical analysis of the transient processes during switching on and off of the electric motor using a circuit based on IGBT transistors was carried out. The analysis of the load characteristic of the electric motor at start-up shows that in the initial section the voltage increases according to a linear law. After the initial increase in voltage, it reaches the set value and the electric motor operates in the operating mode. The analysis of the load characteristics of the electric motor when it is turned off shows, that when the power is turned off, the motor can’t stop immediately, as the phenomenon of self-induction occurs. When the external voltage is turned off, its change on the electric motor occurs according to the exponential law. It is shown that for controlling the operation of the electric motor, it is more appropriate to use an electric circuit based on IGBT transistors, which provides conditions for more stable and safe operation of the electric motor. Using the electrical circuit allows you to find quickly malfunctions for their further elimination. The electrical circuit allows you to avoid physical wear of its electrical elements. Originality. An electrical circuit for controlling an electric motor based on modern electronic components has been developed, which allows the use of IGBT transistors instead of electromagnetic contactors. On the basis of the analytical and calculation method and graphical analysis, the expediency of using IGBT transistors instead of electromagnetic contactors has been proven. Practical value. The developed electrical circuit can be applied to control a 700 W direct current electric motor for operation in diesel locomotives. The proposed electrical circuit allows to increase the mobility of repairs in the event of a malfunction by replacing the corresponding unit.

“…The second problem is solved through the use of bistable mechanical latches, known for a long time [3][4][5]. A mathematical model of the drive with optimal control of the IDM armature speed and mechanical bistable latch was considered in [4] and investigated in [6], where the main disadvantages of such a model are shown. In [7], a Thompson-drive was considered, and an electromagnetic latch is used as a position latch.…”

“…The software allows optimization calculations with a change in the cross section of the winding wire. One of the main parameters to be set is the full stroke of the system's armatures equal to 7 mm [6] and the stroke to the contact touch of 5 mm. The force of contact pressing was assumed to be constant and equal to 200 N, the initial mass is 0.9 kg (see Fig.…”

Introduction. Recently, in the literature, inductive-dynamic mechanisms (IDMs), known in foreign literature as a Thomson-drive, as a drive for various electrical devices are often researched and developed. The simplicity and reliability of the design, high speed make such devices indispensable in high-speed electrical devices standing in DC networks, in which emergency overcorrects are not limited by the reactance and can reach significant values. The novelty of the proposed work consists in the development of a mathematical model and the study of the Thompson drive, in which a bistable two-position mechanism consisting of a magnetic system with permanent magnets, is used as the final position latches. The movement of objects is carried out by deforming the computational mesh. The problem is a multiphysical one, in which a parallel solution of several tasks of different nature is considered. Purpose. Analysis of the fundamental possibility of creating a switching device with an induction-dynamic drive on the basis of a mathematical model which allows to increase the reliability of the entire mechanism operation and significantly simplify the design. Methods. The solution of the problem was carried out by the Finite Element Method in the COMSOL package in a cylindrical coordinate system. Results. A mathematical model of a new fast-driven induction-dynamic drive with a bistable mechanism, based on the equations of the electromagnetic field, electric circuit, equations of motion, was developed and partially studied. The model allows to calculate the dynamic parameters of the drive based on the initial data. Conclusions. The principal possibility of creating a high-speed actuator of switching devices based on an induction-dynamic mechanism and a polarized bistable mechanism based on permanent magnets is demonstrated. The research directions of the model were determined for the subsequent implementation of the results in experimental samples. References 11, table 1, figures 13.
