1. XXXXX Ventilatoren was interested in substituting AC motors in their applications with more efficient EC motors. 2. Sunon focused their development efforts on the XXXXX fan insert XX NNN, which uses an AC motor, with the goal of replacing it with a smaller 62mm diameter EC motor from Sunon. 3. Testing showed the Sunon EC motor could achieve the same performance as the original AC motor while saving 45-50% in power consumption.

3. I . Commercial approach
XXXXX Ventilatoren met Sunon during Frankfurter ISH trade fair where Mr. Xxxxxxxx, its
product manager, has discussed about EC motors with Andreas.
This prospect was already a target focused on Schukat 2015 kick off action list to provide
EC motors on German market (as HELIOS for example).

4. II . Customer needs
Andreas and Yann went to XXXXX at There-Nswe (Germany) last 22nd
April.
XXXXX R&D submits different current projects.
In those different projects, among other needs, XXXXX would like to substitute its AC
motors by EC motors in its applications ranges.
To begin, Sunon decides to focus on 2 projects, those which are most similar with our EC
motor developments and other customer requests (like ATLANTIC for exemple)
