Abstract: This paper presents the electromagnetic
and thermal characteristics of a novel canned Switched Reluctance Machine
(SRM) as a hydraulic pump drive. Due to considerable loss generated from the
can shield in airgap, the characteristics are of fundamental differences
from an ordinary machine. To identify the can effect, the magnetic field and
heat transfer are respectively identified, followed by a coupled analysis
due to high temperature rise on the can shield that significantly affects
airgap flux. Specifically, improved thermal and electromagnetic models are
respectively proposed to enhance calculation accuracy with small
computation. Then, the coupling between airgap flux and temperature rise on
the can shield is studied. The electromagnetic and thermal features are
validated with measurements.
