ABB's Motor Guide provides basic technical information about low voltage (LV) standard electric motors:

ABB's General purpose motors are readily available from central stock locations and distributors throughout the world. While designed for standard and straightforward uses, the motors can be modified to meet most specifications. Built to the highest manufacturing standards, general-purpose motors use the best materials sourced from around the world. This brings a quality and reliability that can see motors operating for over 30 years. Competitively priced, the motors meet EFF2 energy efficiency classification, with EFF1 as option.
This Guide explains the product offer, quality standards and other standards met, technical and design aspects, IT support, energy saving and environmental aspects, the benefits of high efficiencies, and the motors within ABB's Environmental Management Program.
