摘要
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.
