Over the past few decade, several novel linear motor topologies including switched reluctance linear motor (SRLM) and doubly salient linear motor (DSLM) have been extensively researched for long distance direct drive applications due to the increasing demand of low cost, low PM consumption and simple structure [1]–[2].
Due to the high efficiency and force density, linear switched flux permanent magnet machine (LSF-PMM) is gaining more and more attention in direct drive technology. For conventional LSFPPM, the structure enables the PMs and windings to be arranged on the same side, which largely reduces the manufacture cost [1]. However, with the insert of PMs into adjacent teeth, limited by the volume of primary,...
Tamping machine is one of the pivotal devices for coking plants. Most tamping machines are still driven by rotatory electric motors, through mechanical transmission components, leading to low energy efficiency, slow working frequency and huge maintenance fees. In fact the tamping machine can be directly driven by linear motors as shown in Fig.1. Directly driven system will be simpler with higher working...
In order to lower the cost, the switched-flux linear motor (SFLM) is proposed by combining both PMs and armature windings in short mover, which avoids long armature or long PMs as normal PMLMs. Moreover, SFLM combines the merits of linear motor and rotatory switched-flux motor, so they exhibit the advantages of bipolar flux-linkage and high thrust force density. It is more appropriate to be applied...
