Baldor Electric Company offers an expanded line of high voltage rib-cooled motors, type NXR, with higher power ranges and increased ingress protection. The NXR motor platform is based on the established HXR range.
The platform is available in frame sizes 355 – 450 and in the power range of 100 – 1250 kW. The entire power range is enhanced with optional increased protection ratings up to IP66, important for applications where dust is present, such as in the mining and cement industries. The enclosure is completely dust tight and will withstand powerful water jets
Pre-engineered fixing points make it easy to install accessories on the outside and ensure that airflow over the cooling surfaces is not affected, according to the company.
Easy access to the coil ends and bearings simplify maintenance. The parts can be inspected with an endoscope without the need to remove the end shields. A wide range of standardized accessories includes two advanced condition monitoring systems – ABB MACHsense-P and ABB MACHsense-R – that can detect potential problems early before they become serious.
