“…Such an IDD drive model was implemented and described in detail in [9,15]. Due to the fact that the implementation of the circumferential part of the model existing so far makes it impossible to simulate discontinuous energy transfer, appropriate modifications have been made.…”

Abstract:The paper deals with a key issue, how to limit the hazard and assure reliability, safety and repeatability of operation of selected critical devices protecting electrical power systems. The main research is focused on the incorrect operation of hybrid switches caused by random disturbances of the thyristor gate signals in the electrodynamic drive coil power supply circuit. Firstly, a pilot experiment on the operation of hybrid circuit breaker actuators under random disturbance conditions was carried out and the results are presented. Next, an in-depth operation analysis, based on experimental and simulation research, according to setting conditions of the circuit breaker actuator parameters such as capacitance, voltage and switching time was performed. A simulation study with the use of a field-circumferential model in the Ansys Maxwell program of electrodynamic propulsion of rectilinear motion, which enables energy transfer from the capacitor bank to the actuator coil power supply at selected time intervals, was executed. The study analysed the impact of the discontinuity of energy transfer on the dynamic properties of the actuator and some recommendations for designers and users on how to limit this hazard are formulated.

“…It follows that the electrodynamic actuator must be characterized by repeatability and a suitable duration of action [7][8][9]. The necessity of complying with these requirements is a reason for the continuous research and study of the impact of influencing disturbing factors for electrodynamic actuator-propulsion operation.…”

“…For analytic estimation, in order to investigate the correctness of the model, the coil's self inductance was calculated using analytical equations [15][16][17][18][19][20]. It is assumed that the coil contains N circular turns, and the turns themselves are circular in cross-section (Fig.…”

Abstract. The paper describes an efficient method of magnetization of permanent magnets, mounted on synchronous and BLDC motor rotors, which employs an air coil. A developed mathematical model of an electromagnetic circuit is presented, which was simulated in an ANSYS-MAX-WELL environment. The performed simulations and experimental tests allowed optimization of the physical process of magnetization of permanent magnets mounted on an electrical machine rotor. The adopted method allowed achieving more favourable conditions of magnetization -less financial expenditure allowed to achieve the same results.

“…As a result of the dynamic capacitor discharge, strong electrodynamic interaction takes place between the coil and the disc causing not only the movement of the disc but also its deformation. Therefore there was a need to create more accurate IDD model than hitherto, which would designate not only the distribution of electrodynamic forces acting on the disc [4], but also the mechanical behavior of the system including the stress distribution under the influence of these forces. A comprehensive model will allow for such a design of the physical actuator, which will operate in a reproducible manner which is a condition of a synchronous operation in a circuit breaker.…”

-Inductive dynamic drives (IDD) are ultra rapid actuators where the moving part (disc) is subjected to impulse force. This paper presents the second model of inductive dynamic drive -a mechanical model where analytic-numerical approach was applied. The magnetic pressure, which was determined on the basis of the results obtained in the electrodynamic model, becomes the input data for mechanical model. Research with application of the mechanical model is necessary in order to determine the proper disc oscillation frequency and to obtain the stress state control for drive elements to be designed. Also, the selection of drive parameters to keep the disc deformation insignificant (while oscillating) is a condition under which these models do not need to be coupled together.
