Summary: | High-speed machines exhibit the advantages of super-high-power density, high efficiency, etc. and have been gaining more research attention in recent years. This article proposes an elaborate high-speed vernier reluctance machine (HSVRM) topology. The main advantages are as follows: (1) the stator adopts the so-called half-quasi-squirrel cage winding so that one side of all conductors is short connected and the other side is powered by modular inverter, (2) dc-biased current is fed into each conductor independently so that the machine can operate with the principle of magnetic field modulation, and (3) ladder rotor is equipped to weaken the torque ripple of the machine. Obviously, the machine topology significantly resolves the shortage of overlong end length and improves the fault-tolerant ability. In this article, the basic principle and electromagnetic characteristics of the machine will be analyzed by finite element analysis (FEA). |
