Marine Expertise
Nidec Power manufactures high-quality alternators built to endure both time and the harshest conditions. We carefully select premium materials and design with a focus on reliability and performance. The expertise of our skilled workforce ensures the highest standard of craftsmanship.
As a result, most of our alternators are inherently designed to meet marine specifications, with no modifications needed to comply with some of the world's strictest regulations. With a proven history of excellence, Nidec Power is committed to delivering top-tier performance. Our alternators power high-demand commercial and industrial sectors worldwide.
Product Features
Class H Insulation: Our alternators are Class H insulated, meaning we source top-quality materials from trusted suppliers to guarantee a product with superior heat-resistance. The entire rotor-stator system is carefully impregnated with a special insulating coating to protect it against dust and wear. The result: longer life, better performance.
Compact Design: Sometimes, gaining a few inches is critical, especially aboard vessels with limited space. Our alternators designed to provide maximum power with minimum footprint. Our patented cooling and AREP excitation technologies allow us to offer the most compact alternators on the market.
Robust Design: Vibration is the enemy of any rotating machine. In the design phase, our engineering teams analyze the impact of vibrations through finite element modeling, and we provide 3D models of our products to help their integration in gensets or on ships. Internal vibrations are reduced through anti-vibration mounts for sensitive components.
High Motor Starting Capability: Reliable motor starting is a key requirement for marine alternators, to ensure bow thrusters, winches, and rudders get the power they need, when they need it. Our alternators are optimized with digital regulation features allowing soft start and load impact adjustments, and their electrical and mechanical design allows them to sustain 300% nominal load for 10 seconds.

SAPMER’S -40°C deep freeze tuna purse seiner with a Diesel electric propulsion system.
In 2009, the Piriou shipyard delivered Franche Terre to SAPMER, first of a series of three -40°C deep-freeze Tuna purse seiners for Tuna fishing in the Indian Ocean with a Diesel Electric propulsion system.
The 90-meter long ship is equipped with 4 alternators LSA 53 M9 1875kVA 690V 1000rd/min, driven by Wartsila engines. The alternators provide all the energy needed to operate the ship (hydraulic, -40°C freezing holds, propulsion, lighting, various auxiliaries, etc.)
