Abstract

In this paper we will review two special grades of Sm-Co magnets: the ultra-high temperature grade and the sequentially laminated grade, and the advantages of their use in shipboard propulsion systems for Navy electric ships. Three particular major applications of these magnets are discussed: 1) high temperature motors, 2) high temperature magnetic bearings and 3) high speed motors.
