The 4E Electric Motor Systems Annex (EMSA) provides a platform for an in-depth technical and policy exchange between members and is a vehicle for collaborative projects. Some of its research results are made publicly available.

Up until 2019, EMSA had 6 member countries: Australia, Austria, Denmark, Netherlands, Switzerland and the USA. In 2019, Sweden joined the collaboration and just recently the European Commission also decided to join EMSA.

EMSA welcomes the latest two new members!
