The brake roller is one of the elements for the safe operation of gravity flow pallet racks. The brake roller of the magnetic (eddy current) type magnetic brake roller (MBR) is the most promising brake type. The working principle of the MBR is based on electromagnetic induction laws, according to which the braking of a conductor moving in the magnetic field is caused by the interaction of the conductor's eddy currents with the external magnetic field. In the paper, a mathematical model of the pallet motion on an MBR was developed. The equation of motion of the pallet on the MBR was derived. The calculation results were compared with the results of experimental studies of the pallet motion velocity on the MBR. For pallet speed under “drag peak” speed, the error of the mathematical model is <7.7%, and the error starts increasing once over the “drag peak” speed. Additional investigation of the coefficient of magnetic viscosity for speeds greater than the “drag peak” speed is required.
