Taiyo’s New Energy Saving System

OverHang Permanent Magnet Shaft Generating system

Our new OverHang Permanent Magnet Shaft Generating system have the following features and can contribute to energy saving for vessels.


1. Contributes to optimum hull design.
Increasing the vessel speed requires a slim stern shape so an inline-type SG has been obstructive to this hull shape, while the overhang-type SG is not.
2. Space-saving slim design
Our overhang-type SG is very slim and do not require a reduction in cargo space to make room for the SG.
3. Weight reduction by using permanent magnet
Fitting a permanent magnet to the rotor eliminates a significant number of parts and reduces weight.

4. Increased power generation efficiency.
Fitting a permanent magnet to the rotor eliminates excitation loss, SG efficiency improvement over the conventional SG.

s a leading manufacturer of electric equipment and machinery for marine use, we manufacture and sell electric equipment and machinery, including generators, various electric motors, ventilation fans, switchboards, starters and engine control consoles as well as system products such as shaft generating systems and inverter control systems.
We are the only company in Japan that can deliver a complete range of important electric equipment and machinery for marine use, ranging from rotary machines and their controllers to main marine engines and main auxiliary machinery control consoles.
Taking advantage of our wealth of experience and expertise as a total supplier, we provide equipment and systems tailored to each vessel environment, thus earning the trust of the marine transport and shipbuilding industries in Japan and around the world.
