Analysis and loss reduction of a canned switched reluctance drive from the windings perspective

The can loss is the biggest constraint for canned drives at high speed. In this paper, the can loss of a canned switched reluctance machine (SRM) is analyzed. Then, the can loss is reduced by investigating topology of windings based on the spatial winding distribution theory. A new mathematical model is built up by considering arrangement of wires within a coil. The proposed winding topology is verified by simulation that not only can loss but iron loss can be suppressed at any speed and meanwhile the active torque is enhanced.
