Explosion-proof servo drive
NEW: Servo drive technology for potentially explosive atmospheres
There are many areas in industry that are subject to the European directive 94/9/EC (ATEX 95). This directive and the respective standards must be observed in the chemical industry, the timber industry, or the food and beverage industry for example. Some sectors such as the printing industry and the pharmaceutical industry where this is less obvious are also affected by this directive. Adequately safe drives are also required for sectors where potentially explosive air/gas or air/dust mixtures develop only occasionally (zone 1/zone 21), or rarely or briefly (zone 2/zone 22).

Especially for these tasks and in order to be able to use servo drive technology in these areas as well, SEW-EURODRIVE has qualified servo gear units and servomotors in conjunction with SEW-EURODRIVE frequency inverters according to this directive.
