A Ferromagnetic Mass Flow Technique inside a Cylindrical Surface

摘要

Theoretical backgrounds of magnetic field flow inside stable objects, for example, inside a cylindrical surface, are considered. A cylindrical surface is used in the form of dielectric bushing. Three (or a multiple of three) coils are placed outside the bushing, and a three-phase voltage is supplied via crystal diodes to the coils. Coils generate a magnetic field sequentially inside the bushing with shifts in space and time. The magnetic field is coupled with a ferromagnetic body of a certain size placed inside the bushing and moves it. The proposed ferromagnetic mass flow technique inside a cylindrical surface may be used for shot peening of a part's surface after removal of the shot damping effect at the final stage of the flow. The proposed model of the magnetic engine may be in demand in the case of a low rotational speed of mechanisms or working machines.
