This invention discloses a transverse flux linear-rotary switched reluctance generator with an overall axisymmetric decoupled drive structure. The stator module is composed of upper, middle, and lower stators layered axially. Single-phase linear windings are evenly distributed on the outermost salient-pole stator teeth, while three-phase rotating windings are arranged on the innermost stator yoke. The moving parts include a centrally located double-sided segmented rotor and three external mover flux rings. The internal rotating stator is interlocked with the external linear stator, resulting in a compact structure. Based on the transverse flux principle, the rotor and mover movements are perpendicular to the air gap flux, and the linear and rotating magnetic circuits are relatively independent, resulting in minimal magnetic coupling and electromagnetic decoupling. The control circuit uses fewer power switching devices, supporting multi-mode drive including series, parallel, and hybrid series-parallel windings, thus widening the speed range. This motor features low-speed, high-torque characteristics, eliminating the need for a gearbox in hybrid power generation systems, and is suitable for low-speed direct-drive combined power generation applications such as wave energy and ocean current energy.

This invention discloses a multi-parameter collaborative design and optimization method for an induction coil transverse magnetic heating system, belonging to the field of induction heating technology for metallic materials. The method first clarifies verification indicators such as induction coil safety and system power consumption, as well as optimization objectives related to workpiece temperature. Based on the electromagnetic-thermal coupled finite element analysis method, a finite element simulation model is constructed, integrating parameters from three aspects: electrical, coil, and heat dissipation. Through multiple rounds of iterative optimization, the parameters are collaboratively adjusted to meet the requirements of workpiece average temperature and temperature uniformity. Simultaneously, the induction coil current density, voltage, temperature, and system power density are verified. This invention overcomes the limitations of isolated design parameters in traditional methods, realizes visualization of the heating process, reduces design errors and costs, balances system reliability and low operating costs, and has strong universality, adaptable to different workpieces and production needs.

The present invention relates to linear permanent magnet synchronous machines equipped with a device for minimizing the longitudinal edge effect. Intrinsically, this phenomenon gives rise to several limitations, such as: (i) a fairly marked amplification of the tooth force, which affects the quality of the force developed, (ii) an imbalance of the fluxes cut by the phases, resulting in unbalanced electromotive forces, and (iii) a local increase in transverse magnetic forces, which generates a vibration of the slider and annoying acoustic noise. The present invention proposes a device for minimizing the longitudinal edge effect in the case of long-stroke machines, whether tubular or planar in topology. It consists of two laminated ferromagnetic pieces having an "L"-shaped cross-section, mounted near the ends of the stator ferromagnetic circuit. Such a device allows for the collection of a portion of the flux generated by the slider poles located at the stator ends and its injection into the extreme stator teeth. The shape and location of these components are determined using a numerical dimensioning procedure. The proposed device improves the performance of long-stroke permanent magnet linear synchronous machines. Their integration into various sectors, such as energy, mobility, and robotics, is at stake.

The application provides a polarization separation end face coupler and a linear design method thereof. The coupler comprises a bottom silicon substrate, a silicon oxide under-buried layer, a waveguide structure and an upper cladding layer. The waveguide structure is composed of two groups of waveguides in the same horizontal plane. One group of waveguides has two thicknesses and is used for coupling with an optical fiber and transmitting a transverse electric mode (TE) mode optical signal.

Based on the planar waveguide coupling structure, a waveguide linear design method is provided. The linear design of the coupling waveguide is optimized for different wavelengths, and the high-efficiency, large-bandwidth mode field coupling and polarization separation function of the optical fiber to the optical chip optical field are realized.
