This is the PTO stage 1 project summary report for the Ecosse Subsea Systems PECMAG project. The PECMAG PTO system is a modular all-electric system with magnetic gearing that is being developed to suit a variety of WEC devices. The system can be configured as linear or rotary PTO options that offer flexible installation and deployment possibilities. There is no physical contact between the magnetic gears and so the system is able to ‘slip’ at high loads without damage. This project aims to demonstrate enhanced availability, torque and rated power/£ ratios, combined with inherent efficiency and survivability improvements, to bring the technology closer to market.
