“…Design analysis was carried out using ANSYS MAXWELL software, which allowed for the simulation of the thrust force, linear speed, and other parameters of the motor. In paper [25], the authors presented the design optimization of an LIM. The objective function of the optimization problem includes power efficiency, output thrust, and the total weight of the device.…”

Standard hydraulic breaking hammers are widely used for crushing oversized blasted materials and concrete structures demolition in industry. These hammers, installed in on-surface working excavators or stationary manipulators at the dumping points of underground conveyors, provide the required limited sizes of bulk materials and enable the safe operation of other equipment (screens, crushers). In parallel, hydraulic hammers have an alternative—fully electric hammers. This paper aims to review existing linear electric motor (LEM) hammers as an energy-saving and eco-friendly solution in industry. Global market analysis is presented with potential branches of LEM hammers. Several aspects for implementation—design optimization, dynamics simulation, machine control, and performance estimation—are considered. Different case studies for LEM-hammer application are given. The preliminary measurements are demonstrated on the electric hammer of Lekatech Company, which is intended for the mining industry and construction demolition. Experiments showed that depending on the impact frequency, type of rock, and shape of the crushing tool, the time to fracture varies significantly. Optimal parameters exist for every case, for which adjusting requires online hammer control.

The low-speed Maglev train adopts single-sided linear induction motors (SLIMs) as traction part. Although the phase winding normally adopts single-branch in order to avoid circulating current caused by longitudinal end effect, the influence of circulating current is not investigated in detail. This paper calculates the circulating current and force performance of SLIMs with dual-branch by 3D finite element method (FEM). Firstly, two kind connections of dual-branch phase winding are introduced, called continuous connection or interval connection respectively. Secondly, the circulating current and force performance are obtained at both starting and steady state, and then the effect of circulating current on force performance is deduced. Thirdly, the contribution to force performance by each coil assembly is studied. Finally, the circulating current, force performance and efficiency under different air gap length are analyzed. It is demonstrated that the dual-branch connection has better force performance than single-branch one, but also bigger current unbalance and lower efficiency.
