Abstract: Electromagnetic vibration actuators play a crucial role as the drive elements of industrial vibration conveyors, which are used to transport granular and bulk materials in various process industries, including the food, pharmaceutical and agricultural sectors. The electromagnetic force generated in these actuators significantly depends on the magnetic properties of the actuator core. The magnetic circuit of the actuator consists of an air gap and a ferromagnetic core, which is usually composed of iron sheets with a non-linear magnetic permeability, which is directly dependent on the excitation current. This paper analyses two characteristic cases related to the generation of electromagnetic excitation force: (1) when considering only the air gap in the magnetic circuit and (2) when considering the complete magnetic circuit, including the material with nonlinear magnetic permeability. The influence of magnetic nonlinearity on the excitation force was estimated using the finite element method (FEM) in the Maxwell software package. In the final part of the paper, the key results of computer simulations for both considered cases are presented and analysed.
