Zusammenfassung:This paper describes the operation of a direct-drive brushless generator for a Bristol Cylinder ocean wave device. This is a very low-speed device; thus, the pole number and diameter are very large. Although the machine may be large, its pole pitch and axial length is low. The application is described and simulated using analytical and finite-element analysis techniques. A 248-pole design with surface rotor magnets is developed with both surface and slotted windings. An analysis of the control is put forward.
