Abstract

To optimise coil design for creating an efficient electro-magnetic system characterised by high precision, the present study investigates the impact of varying coil geometry on the electromagnetic force generated bet-ween a pair of coaxial cylindrical coils. The study utilises a multifaceted approach to identify the rela-tionships between axial magnetic force, air-gap dis-tance and coil radial thicknesses. Systematic changes in coil geometry are made to understand the sensitivity of electrical power consumption to the generation of magnetic force, and an analytical model is used to un-derstand the relationships. In this article, limitations on the conventional magnetic force computation meth-od established by previous researchers are identified. Additionally, the results indicate that using thicker coils significantly increases magnetic force production. This advantageous amplification is counterbalanced by increased coil resistance, inevitably leading to reduced efficiency of electromagnetic force production. A mathematical model is developed here for computing the coil efficiency, and methods are proposed to simul-taneously optimise the generation of magnetic force by coils while ensuring.
