Sources and licences

As of 12 November 2026

From the sources listed below SpecCodex takes facts only: figures, designations, part numbers and dimensions. We do not copy texts or images from these sources. For every record in our source database we store the source, address, licence and retrieval date. Where a licence requires attribution, it is given on this page. Model pages additionally name their own sources.

On the area pages (engines and motors, components, standard parts)

  • GEMS electric motor register, Australia – dataset “Historical Energy Efficiency data – Electric Motors” (as of February 2021), energyrating.gov.au. Licence: Creative Commons Attribution 3.0 Australia (CC BY 3.0 AU), licence text. Taken for electric motors: power, number of poles, voltage, efficiency (values for 50/75/100 %), weight, torque, frame size, degree of protection, mounting type, registration status, country of manufacture. The values were selected and processed.
  • European Environment Agency (EEA) – CO2 monitoring of heavy-duty vehicles. According to its legal notice the EEA publishes its content under a CC BY licence; source: European Environment Agency. Used to link truck models to engines, and for transmissions and axles.
  • U.S. Environmental Protection Agency (EPA) – certification data for nonroad diesel engines, heavy-duty highway engines (including model years 2012 to 2016) and marine engines. Works of the U.S. federal government are in the public domain (17 U.S.C. § 105). Used for engine key figures and part numbers (e.g. turbochargers, injection, sensors) with the statement “fitted in engine”.
  • Manufacturer documents – manufacturer PDF catalogues, for electric motors 196 catalogues from 78 manufacturers; also Deutz (Engine Finder), Hatz (data sheets), SKF (catalogues of rolling bearings and radial shaft seals) and Optibelt (product catalogue). Only key figures are taken, no texts or images. We do not claim an open licence for these documents. For every electric motor taken from a catalogue the catalogue and PDF page are given. Trademarks belong to their owners.

What an entry does not mean

A catalogue or register entry does not show that a product is available today, that it is approved for a particular use (for example on board a ship), or that two motors are directly interchangeable.
