Both mechanical and electrical standard versions of Rotor NL® electric motors can perform in marine and offshore applications.

Rotor has adapted and produces electric motors for lower and upper deck use. If necessary, these motors can use a fitted break or an encoder. Depending on the requirements of the application, motors can use IC410, IC411, IC416 or IP23 enclosures. We specialize in special coating systems and elevated IP class designs improving the reliability of the motors even under the harshest conditions.

Specifications

• kW: 0.18-2500

• IEC frame size: 63-355

• Protection class: IP23-IP66

Cranes, hoists and winches for the oil and gas industry

The oil and gas industry uses cranes, hoists, winches and other special handling equipment, particularly on oil rigs and platforms. To withstand rough environmental conditions, these applications need very high reliability and robust design features.

• To enable operation across a speed range, you’ll see variable frequency drives on motors powering cranes, hoists and winches.

• Rotor NL® motors typically feature excellent torque speed characteristics, efficiency, reliability, sustainability and compliance with applicable standards for use in hazardous areas.

• Rotor can make special designs to suit the exact application needs for customers

• End users can expect after-sales support.

Rotor supplies reliable, energy-efficient motors for complex applications such as winches and cranes for the oil and gas industry. Discover our world-class IE4 and IE3 industrial and ATEX motors.

Port Cranes play an important role in container terminals or yards by stacking containers or loading them onto waiting vessels.

• Along the quay side of the port, you’ll find Quay Cranes or STS (ship to shore) Cranes, located there for easy access for container ships.

• Deeper in yards, you’ll find Yard Cranes (commonly RMG or RTG cranes), used to move containers from the yard onto trailers.

• Rubber Tired Gantry (RTG) cranes

• Rail Mounted Gantry (RMG) cranes

Typical applications are Boom, Gantry, Trolley and Hoist.

Offshore cranes play an important part in heavy duty lifting under extreme conditions for deep sea or oil and gas environments. If mounted on a vessel, a crane’s operational temperature may vary from tropical heat to polar cold situations. High waves on the open sea add another challenge, requiring robust engineering.

Rotor NL® motors are used in other important offshore applications such as:

• Lifesaving davits

• Jack-up systems

• Fixation systems

• Winches

• Skidding systems

Water treatment is any process that improves water quality to make it appropriate for a specific end use. End uses include drinking, industrial water supply, irrigation, river flow maintenance, water recreation and others, including safely returning the water to the environment. Wastewater treatment (or sewage treatment) is the removal of impurities from wastewater (or sewage) before it reaches natural bodies of water (such as rivers, lakes, estuaries or oceans). In order to meet water specifications, utilities and OEMs can specify a motor for any pump (or compressor or fan application) used in the water and wastewater sector. Applications powered by electric motors are found at every stage of water treatment. Another energy-saving factor coming into common use is variable frequency drives. Any motor used in water treatment must deliver high-class performance.

While energy efficiency is the key buzzword, other factors such as safety, reliability, sustainability, close adaptation of the solution as well as after-sales support are considered key to end users.

Mechanical systems not only ventilate indoor spaces, but they also heat, cool, humidify and dehumidify. Forced ventilation systems powered by electric motors create pressure difference to move air in the desired direction and keep air quality at an acceptable level. In order to meet fan requirements, utilities and OEMs can specify motors to be used in a ventilation system. Specifications feature required input parameters such as load inertia when used with DOL /Star Delta/Reduced Voltage fixed frequency supply system. Another energy-saving factor coming into common use is variable frequency drives, which makes selection of the motor easier. With a variable frequency drive, the starting time does not affect the size of the motor. Any HVAC motor must deliver high-class, reliable performance to ensure the performance of the fan and consume less energy and reduce carbon dioxide emissions.

• HVAC systems are used in commercial and residential buildings, as well as data centres and in tunnel ventilation systems.

• While energy efficiency is the key buzzword, other factors such as safety, reliability, sustainability, close adaptation of the solution as well as after-sales support are considered key to end users.

Industrial-grade air compressors are the workhorses of manufacturing plants and a reliable power source on oil rigs. They provide a steady flow of compressed air for long periods of time but also can withstand fluctuating surges in use that are typical in major manufacturing plants. These compressors require high-quality, efficient and reliable electric motors that allow for environment-specific customization to improve performance, energy efficiency and reliability. Compressors are used across numerous manufacturing sectors like chemical, petroleum, utilities and water management. With that in mind, demand for compressors is tied to the broad macro-economic environment.

• Variable frequency drives are also commonly used for energy conservation.

• While energy efficiency is the key buzzword, end users consider other factors like reliability, sustainability, mechanical adaptation of the motor for stable system design and performance as well as after-sales support.
