APPLICATION OF A HIGH-ENERGY-DENSITY PERMANENT-MAGNET MATERIAL IN UNDERWATER SYSTEMS

This paper addresses the application of high-energy-density permanent magnet (PM) technology to (1) the brushless, axial-field PM motor and (2) the integrated electric motor/pump system for underwater applicati ons, Finite-element analysis and lumped parameter magnetic circuit ana lysis were used to calculate motor parameters and performance characte ristics and to conduct tradeoff studies. Compact, efficient, reliable, and quiet underwater systems are attainable with the development of h igh-energy-density PM material, pow er electronic devices, and power i ntegrated-circuit technology.
