This paper proposes a linear doubly-salient high-temperature superconductor (HTS) machine for wave energy conversion, which is composed of a tubular stator and a tubular translator. Since the translator is a simple iron core with salient poles, it is so robust that it can be directly coupled with the reciprocating buoy. The stator consists of an iron core with salient poles, DC HTS field windings...
In this paper, a new permanent magnet (PM) linear motor is proposed, in which both the magnets and armature windings are placed in the short mover, while the long stator consists of iron core only. Hence, this new PM linear motor can be called as primary permanent magnet linear motor, which exhibits the advantages of robust and simple mover, low cost, high efficiency, high power factor, and high thrust...
The hot compression experiments of roller steel Cr5 were carried out on Gleeble-3500 thermo-simulation machine to research on the effect of deformation on grain size distribution. And finite element models of compression processes were built to acquire the strain distributions in the deformed samples. The microstructures observed by metalloscope show that fine grain sizes were obtained in central...
A low-speed double disks type permanent magnet synchronous machine is proposed. The electrical machinepsilas stator slot number is close to the rotor permanent magnet pole number and the statorpsilas tooth width is close to a pole distance. The coils that belong to each phase are concentrated and wound on consecutive teeth, so that the end winding is minimal and the phase windings do not overlap....
A new type of three-phase permanent magnet synchronous machine (PMSM) with modular stator structure is proposed. Its structure and principle is introduced. The machinepsilas teeth width is equal to polar pitch, its stator winding is concentrated winding, each phase winding is wound up continuously and the ends of windings are shorter then conventional machines. Therefore, the machinepsilas efficiency...
