Constructed with NEMA 5800 (368.5mm, 14.5inch shaft height) frames, the induction motors can deliver up to 1,750 horse power.
They have “high-strength welded steel frame construction usually reserved for larger motors reduces stress and vibration to ensure a long service life”, said ABB. The “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”.
Design life is 25 years or 20,000 starts, vibration is Grade A or B.
As well as new-builds, the motors have been designed as drop-in replacements for existing equipment.
“Its modular design in terms of cooling methods, bearings, shaft extensions and terminal boxes provides the flexibility to match the North American installed base,” said ABB UK sales manager Stephen Clabburn, adding: “From a UK perspective, for OEMs exporting to the North American market, ABB is now able to support you locally with this generation of NEMA designs. Further customisation will allow some models to operate above the IE4 equivalent level of energy efficiency while meeting NEMA electrical performance standards.”
Options include: 5810 – 5812 frames and operation from 460V, 2.3/4,16kV or 6.6kV, at 50 or 60Hz.
Maximum power depends on the number of poles selected: 1,500hp for two poles, 1,750 for four, 1,000 for six and 750hp for eight.
Its Class F insulation is suitable for starting high inertia loads direct-on-line (DOL), according to ABB, as well as via variable speed drives (VSDs). Service factor is 1.15 DOL or 1.0 via VFD.
