Overview of SIEMENS Industrial Low-Voltage Marine Motor Solution

The SIEMENS Industrial Low-Voltage Marine Motor Solution stands out as a robust, marine-specific power system, tailored to meet the rigorous demands of maritime operations. A key advantage is its exceptional environmental resilience—built with corrosion-resistant cast iron housings, IP55+ protection, and special anti-salt fog treatments, it withstands high humidity, extreme temperature fluctuations (-20℃ to +40℃), and harsh saltwater environments, ensuring long-term reliability on both inland and seagoing vessels. Covering 0.55–4000 kW power range, it integrates seamlessly with SINAMICS drives, delivering stable performance for diverse maritime tasks.

Compliant with IMO Tier II, CCNR, and other global marine regulations, it features IE2+ high efficiency and copper rotor technology, reducing fuel consumption by up to 15% and lowering carbon emissions—critical for marine sustainability goals. Multiple built-in safety protections (overload, overheating, short circuit) enhance operational safety, while its modular design simplifies on-board maintenance, minimizing downtime for vessels where every hour at sea matters. 360° rotatable junction boxes and flexible mounting options adapt to limited cabin space, optimizing installation efficiency.

Widely used in commercial ships, offshore platforms, and inland watercraft, it excels in main propulsion, bow/stern thrusters, and auxiliary systems (pumps, compressors, ventilation). It supports diesel-electric propulsion setups, ideal for cargo ships, ferries, and offshore supply vessels. Its compatibility with marine control systems ensures seamless integration into existing ship architectures, while global certification coverage simplifies cross-region deployment. Combining ruggedness, energy efficiency, and regulatory compliance, it becomes a trusted choice for maritime operators seeking cost-effective, low-maintenance power solutions. (Word count: 398)

OVERVIEW

On basis of the known and proven platform 1LE1, 1LE5 and 1MB1 certified INNOMOTICS DP ship motors are now available.

As consequent continuation of the spectrum motors with aluminum housing and with cast iron housing can be chosen as standard versions as well as versions for hazardous areas.

Specially designed for use on ships below deck and for the offshore industry, our marine motors meet the requirements of the leading classification authorities and have type-test certificates up to 500 kW output.

Especially for on-deck use on ships, we offer our special range of motors for on-deck applications; these continue to run perfectly even after being completely immersed by a wave.
