Tugboats to reap the benefits

A prototype electric motor unit that will achieve the industry's highest class output density for Z-type tugboat propulsion equipment has been commissioned from Yamaha Motor Co. by Tokyo-based IHI Power Systems Co. Ltd.

Yamaha Motor has been developing prototype electric motors for automobiles and other mobility applications since 2020, but this is a first for an electric motor for a Z-drive marine propulsion unit destined for marine tugboats. Using the Yamaha electric motor for the IHI Power Systems electric propulsion will result in a more efficient propulsion system than those using a conventional internal combustion engine and will reduce the environmental footprint overall.

For trial development contracts, Yamaha uses production technology and trial production facilities centred on casting, processing, and assembly, etc.  This approach supports a wide range of products operating across sectors and enables rapid further development according to customer requirements.

Yamaha is expanding its use of electric motors beyond motorcycles and automobiles into marine products and other sectors, keeping the company on track to achieve the goals in the "Yamaha Motor Group Environmental Plan 2050", revised in 2021.
