Abstract

Permanent magnet machines have become an attractive topology for several applications due to their high power density and brushless qualities as compared to conventional wound field machines or squirrel cage machines. The presences of permanent magnets provide distinct advantages, but at the same time unique behaviors that must be accounted for. Recent work has developed permanent magnet machines for high-power and high-speed applications such as may be found in the petro-chemical industry, naval ships, and energy storage systems.
