ABB’s new AMI 5800 induction motor features innovative modular mechanical construction and flexible electrical designs
-
Pioneering use of high-strength welded steel frame construction usually reserved for larger motors reduces stress and vibration to ensure a long service life
-
Motor is tested to meet or exceed North American standards for energy efficiency while bringing high performance to pumps, compressors, fans, extruders, conveyors and crushers
ABB has developed the new generation AMI 5800 NEMA modular induction motor to offer exceptional energy efficiency and reliability in demanding applications such as pumps, compressors, fans, extruders, conveyors and crushers. Rated for a power output of up to 1750 HP, the AMI 5800 offers the capability for a high degree of modularity and customisation to suit both new-build and upgrade projects in a wide range of industries including chemical oil and gas, conventional power generation, mining and cement, and metals. The motor opens up new options for UK OEMs looking to export customers in North America.
The AMI 5800 motor is a true NEMA design that builds on ABB’s technology leadership in the North American market to meet both electrical performance requirements and mechanical mounting standards. A key feature is a high-strength welded steel frame typically found only in motors with larger frame sizes. This lowers stress on the motor while mitigating vibrations and resonance to ensure reliable operation in harsh conditions with a design life of 25 years or 20,000 starts.
A further important advantage of the AMI 5800 is a shorter bearing to bearing span compared with previous models. This innovative feature improves performance at high speeds and enables the motor to be used as a simple drop-in replacement to upgrade existing equipment.
According to ABB’s Stephen Clabburn, UK Sales Manager, Large Motors & Generators: “We have engineered the AMI 5800 motor to meet customer requirements for high energy efficiency and reliability, as well as sustainable manufacture and use. Its modular design in terms of cooling methods, bearings, shaft extensions and terminal boxes also provide the flexibility to match the North American installed base. This makes the AMI 5800 ideally suited for both upgrading existing installations and next generation designs no matter how harsh the environment it will be operating in. From a UK perspective, for UK OEMs exporting to the North American market, ABB is now able to support you locally with this new generation of NEMA designs that build on our already extensive NEMA range.”
The majority of regular AMI 5800 designs not only meet but exceed North American standards for energy efficiency. Further customisation will allow some models to operate above the IE4 equivalent level of energy efficiency while meeting NEMA electrical performance standards.
The new motor is configured for optimal airflow, meaning that it will run as cool as possible, whether in an open-air installation or completely enclosed with a cooler. The time-tested MICADUR® insulation system makes the motor suitable for starting high inertia loads direct on line (DOL), while it is also an ideal partner for variable speed drives (VSDs).
