Motors and generators for marine applications
Marelli Motori offers one of the most advanced and comprehensive ranges of purpose-built rotating machines suitable for marine applications.
Our water-cooled motors are designed for heavy-duty applications where space and natural ventilation are limited. They provide an excellent power output for the compact motor size, compared with traditional heat exchanger designs. They are typically used for main propulsion and thrusters. Powers are available up to 6,400kW.
Hybrid synchronous electric propulsion
An innovative hybrid synchronous machine has been developed and certified by Marelli Motori and is currently patent pending.
This latest technology is a hybrid synchronous motor-alternator with dual AC/DC excitation system for shipboard generation and propulsion applications.
Testing facilities for the maritime industry
Marelli Motori has a state-of-the-art test facility capable of testing motors and generators in their original mounting arrangement (vertical and horizontal). Testing can be conducted at 50Hz / 60Hz and variable speed, as the facility houses a large-power high-frequency AFE inverter (regenerative). Testing is carried out in compliance with all major international standards (IEC and IEEE), customer specifications, marine / navy and ATEX rules.
Marelli Motori marine solutions for essential and non-essential duties are approved by or compliant with all major classification societies.
Maintenance, repairs and training services
Continued customer satisfaction remains the number one priority of Marelli Motori after our products are delivered to the end user. To that purpose, our Marelli Motori service team is able to offer worldwide support and professional advice on maintenance, performance enhancements, commissioning and repairs, as well as training courses.
Marelli Motori has more than 120 years of experience in the design and manufacture of electrical rotating machines to meet the needs of an ever-changing market, through a global support structure of sales, service and distribution offices worldwide.
