Yaskawa Environmental Energy/The Switch has clocked up over 100 permanent magnet machines (PMMs) for in-line shaft generators of various frame sizes since 2014 and has a large order backlog for large LNG and LPG carriers. “Using PMMs for electrical power generation is a game-changer in terms of greater efficiency, reliability and flexibility especially where slow steaming is a desired function,” says Head of Product Line, Electric Machines, Jussi Puranen.
