NORac Induction Motors
Please note that the NORac model is now only available as spares or as a replacement!
A Range of Induction Motors from 250kW to 20MW
Norac motors have proven reliability and cost effective operation in a wide variety of industries and environments. These include offshore, petrochemical, water and power generation, pipelines, mining, marine and both desert and arctic conditions.
The NORac concept is to satisfy the need of individual users economically, with a rationalised but versatile range of machines.
A 'Family of Parts' approach utilises modular construction and standardised manufacturing techniques, to produce machines of simple and robust construction with performance to meet the customers specific requirement.
All machines comply with the appropriate parts of IEC34: 1: 1994, IEC72: Part2: 1991, BS4999: Part 105: 1988, BS5000: Part 99: 1973 in respect of performance and dimensions, therefore meeting the requirements set by the majority of International Standards.
