NORD Drivesystems supplies individually configured drive systems in accordance with EU Directive 2014/34/EU and IEC Ex for application in potentially explosive atmospheres. The drive specialist has many years of experience with gas and dust explosion protection and for more than a decade has produced explosion protected motors which meet even the most stringent requirements. The explosion protected drive systems can be operated in category 2D or 3D dust atmospheres (Zones 21 and 22) as well as in category 2G or 3G gas atmospheres (Zones 1 and 2). A combined dust/gas explosion protection is also available.
NORD supplies application-specific drive solutions with individual configurations and equipment from its SAP-supported modular system with validated configuration processes according to ISO 9001. On the basis of customer specifications, NORD calculates individually by testing the ATEX conformity and also delivers the appropriately modified type plate. If required, the maintenance intervals which are determined for the specific application can be stamped on the type plates.
The company offers flexible drive concepts with motors which are optionally designed for use with inverters as well as the option of IEC or NEMA motor mounting. In many cases, it can be mounted directly on the gear unit for an especially compact solution. Depending on the explosion protection zone, various options can be integrated, e.g. external fan, backstop, brake. The explosion protection range by NORD includes systems for ambient temperatures up to +60 °C and is characterised by delivering world-wide with documentation in more than 20 languages.
In order to maintain the quality of production, inspection as well as the products, NORD Drivesystems works very closely with the Physikalisch-Technische Bundesanstalt (PTB) and the DEKRA EXAM GmbH. All Category 2 motors have type test certification. Explosion protected drives by NORD are used in almost all industry sectors in a wide variety of applications, e.g. to drive pumps, agitators or lifting gear.
NORD Drivesystems develops, produces and sells drive technologies with around 3.600 employees, and is one of the international leaders in the industry. In addition to standard drives, NORD supplies application-specific concepts and solutions, even for special applications, for example with energy-saving drives or explosion-protected systems. The company produces a wide variety of drive units for torques from 10 to 200,000 Nm, electric motors with powers from 0.12 kW to 1,000 kW as well as the necessary power electronics in the form of frequency inverters and servo controllers. Inverter solutions are available for classical installations in the switch cabinet and for decentralised and fully integrated drive units.
