Optimal Design of Uni-Directional Linear Solenoid

The solenoid can be used as a much simpler control operation than a motor in its simple operation. In particular, the latch requiring uni-directional is more useful than the motor. In this paper, a solenoid for operating a latch that moves when a force of more than 5kgf is applied is optimized and designed, and an optimal design proposal is presented by comparing the actual operation characteristic waveform through FEM analysis through coil selection and change of each dimension.
