The article presents the results of a research of the influence of a ferromagnetic shunt (FMS) on the static and dynamic characteristics of the control electromagnet of the KTP 6000 series contactor by means of computer numerical simulation in the ANSYS Electromagnetic Suite software package. A computer numerical model of an electromagnetic actuator with FMS is proposed and verified, the influence of the geometrical dimensions of the shunt on the static and dynamic characteristics of the electromagnetic actuator of a low-voltage DC contactor is investigated. Recommendations are given for the selection of the FMS dimensions in the design calcu-lation of the valve-type electromagnetic drive, which will increase the dynamic traction force of the electromagnet and reduce its response time.

A method is proposed for calculating eddy currents in solid elements of magnetic systems of linear electric generators with permanent magnets. The method is based on the calculated analytical relationships for hypothetical contours of eddy currents released in solid conducting elements of magnetic systems. To check the adequacy of the proposed meth-od, a numerical calculation was carried out on a three-dimensional computer model implemented in the ANSYS Elec-tromagnetic Suite software package verified in accordance with GOST R 57700.11-2018. The studies carried out have confirmed the adequacy of the proposed methodology, the calculation error does not exceed 10 %.
