AB  - Efficiency of induction motors is very much debated these days. Different standards are used in the world, making actual manufacturer numbers hard to compare. Therefore, many motors of 11, 55 and 75 kW have been tested in the machine laboratory of the Electromechanical Engineering department. Special attention was given to the various standards, mainly IEC 60034-2 and IEEE 112 B. The aim was to compare the various motors and to rank them according to their efficiency. Based on these measurements, it was determined that the present IEC standard is not reliable and does not offer the possibility for consumers to make an instructed choice. The reason for this is that the additional load losses, formerly referred to as stray load losses, are not properly taken into account. Comments on the new proposed IEC 61972 standard are included.
