Analysis of flux leakage in a brushless permanent-magnet motor with embedded magnets

This paper analyzes the magnetic characteristics of brushless permanent-magnet motors with embedded magnets. It shows that the flux leakage has a substantial effect on the air gap flux density interacting directly with the armature current to produce torque. The flux leakage parameters /spl eta/ and...
