Description

Compact design, flexible interfaces and low noise make NMI motors easy to integrate into industrial processes. In addition to horizontal mounting, the motors can be supplied for vertical mounting in pumping applications. A special bearing design enables vertical motors to withstand the extra axial force produced by the pump.

High reliability is ensured by the motors’ proven core technology and low vibration levels. ABB’s global service network, providing services that cover the entire life cycle and fast availability of spare parts, helps to keep downtime to a minimum.

NMI motors belong to the N-series of industrial duty motors that are configured to order. The other N-series product families are high voltage rib cooled TEFC (totally enclosed fan cooled) motors, type NXR, available as IEC and above NEMA options. N‑series motors complement the A-series of engineered motors intended for applications where a highly customized product is needed.
