Loher Motor... Ex?
Loher Motor... Ex?
(OP)
I have to find out if a motor is Ex proof. But I cannot find a Datasheet. The motor is a Loher ENGV132MB-42. On the plate there is a marking saying: E Exe II. Can someone confirm or guide me to the manufacturer datasheet to verify if this is a Ex Proof unit?

But other info (German Wikipedia) indicates that they're now part of Siemens. See this page.
Try poking around on the Siemens page. Good luck.

While DRWeig is correct saying “Ex d” is closer, it still isn’t explosionproof; it is IEC “flameproof”. While they are similar in concept, they use different test standards.
The mark as you indicated appears to be ATEX. The first “E” means it is marked for (EU) Zones. The Ex e is “increased safety” suitable for Zones 1 and 2 and the “II” alone is means suitable for all gas and vapor Groups.
In the US, “Ex-anything” is meaningless; it must be AEx. See NEC Section 505.9(C)(2)(3). Again the US domestic test standards are different.
