            Abstract : 
This paper describes two alternative designs of a direct-drive permanent-magnet generator for use in a novel sea-wave electrical generator. The basic system is briefly described and the target specification is given from the wave device. The design for a fractional-slot high-pole number brushless permanent-magnet generator and a torus generator are sized and developed using the design packages SPEED PC-BDC and PC-FEA. The designs are compared. A diode bridge model is also tested using Portunus system simulation. A design for a switched reluctance machine is also briefly investigated.
