New technologies for high-efficiency motor systems in the manufacturing industry

In the manufacturing industry, there is a total savings potential of almost 20% through more optimal operation and use of new motor technology.

In the seven largest industries in the manufacturing industry, approx. 70% of electricity con-sumption for electric motor systems. The savings potential has been calculated at almost 20%. From 1 July 2021, there are stricter Ecodesign requirements for electric motors between 0.12 kW and 1000 kW. The next generation of technology for engine systems is on the way, based on PM technology or synchronous reluctance. The latter, unlike the permanent magnet motors (PM), do not use rare earths, about which there is generally a rift.

For the frequency converters and on the power electronics side, it is especially the WBG tech-nology that is focused on. WBG technology can provide up to 70% savings. In addition, the large savings lie in assembling the motor systems to suit the applications, i.e. the operating time, the loads and the transmission losses to which the engine systems are exposed.

The aim of the project is to identify applications with savings potential, where the new technol-ogies have a particularly positive impact, optimal motor system packages are put together that are tested, so that technologies can quickly become widespread in the market.

In addition, a customized software solution is being developed that adapts to the application based on known loss models from, for example, the big blue and the like.

The project will analyze savings potential and business cases compared to a business-as-usual scenario, where only standard technology is used.

The technologies that are tested and demonstrated are selected in collaboration with Danfoss and three additional manufacturing companies.

The project ends decembre 2023.
