Electric tools have become indispensable in various industries owing to their convenient portability, high energy efficiency, and capability to operate without being constrained by power cords when using batteries. Referring to the currently marketed ST-64 specification gas-powered or compressed-air-powered nail guns commonly used for concrete and steel beams, we propose a linear motor design with superior output power and operational speed for use in electric nail guns. The design process begins with designing and simulating the stator and mover of the motor using Altair Flux 3D finite element analysis software. The stator is a combination of permanent magnets and electromagnetic iron and designed to possess magnetic field properties similar to those of the Halbach magnet array. On the other hand, the mover utilizes permanent magnets with different magnetic field directions to achieve a Halbach magnet array design, resulting in a magnetic field direction opposite to that of the stator. The linear motor, formed by a combination of the stator and mover, is then analyzed and adjusted through Flux 3D finite element analysis to design a short-stroke, high-thrust linear motor leveraging the concentrated magnetic field characteristics of the magnet array. Finally, it is experimentally verified that the linear motor designed in the experiment can achieve an output force of up to an average of 90 N even when using an inferior core, reinforcing the potential and reliability of this design for practical implementation.
