Abstract
This paper presents comparative studies of magnetic characteristics and dynamic performances for two mutually coupled dual-channel switched reluctance machines (DCSRMs) with the same properties and different winding connections. A 2D/3D finite element method (FEM) is used to analyze the magnetic field distributions and calculate the static inductance and torque characteristics of these two DCSRMs. The different static magnetic characteristics, details of mathematical models and dynamic performances prediction at transient and steady states for these two DCSRMs under single- and dual-channel operation modes are presented and compared. Finally, an experimental setup for two high speed 12/8-pole DCSRMs with different winding connections is built. The experimental results of these two DCSRMs such as phase current, average torque, copper loss, iron loss and efficiency under different operation modes are presented and compared to verify the analytical and simulation results.
