Energy Efficiency Safety, longevity and eco-friendliness have always been deeply rooted in our corporate philosophy. This has led us to develop energy-efficient motors a long time ago, independent of the latest European directives regarding responsible use of energy and resources. controls with respect to placing them on the market and commissioning them. IEC 60034-30 In an effort to harmonize the many different national efficiency requirements, the international standard IEC 60034-30:2008 is a first step to achieve consistent international efficiency standards for three-phase low voltage...

7 Identification These types of motors have the letter Y in their designation and are labeled with the associated efficiency class IE and the rated efficiency, e.g. CD 80M1-2Y3 IE3 - 82.8%. Depending on the design, our energy-saving motors are conform with the following efficiency requirements: 1. IE2 Level - High Efficiency according to IEC 60034-30 for international use (introduction on 16 June 2011). 2. IE3 Level - Premium Efficiency according to IEC 60034-30 for international use (introduction on 1 January 2011). 3. Minimum Energy Performance Standard (MEPS) according to AS/NZS 1359.5...

We apply the most stringent quality criteria, which are checked annually by official government agencies. The certification of the quality assurance was implemented for the first time in 1992. Today we have certifications in accordance with: • DIN EN ISO 9001:2008 for the Quality Management System • ATEX according to 94/9/EG, Appendix IV for the production of totally-enclosed flameproof motors. The conservation of our environment through the promotion of non-polluting manufacturing methods, materials and chemicals in energy-saving motors and drives was identified at an early stage and has...

9 All motors meet the following international standards and specifications. Apart from these guidelines, the motors also meet many customer specifications from the chemical and petrochemical and machine building industries. On request, motors can also be supplied according to the recommendations of the VIK (German association of industrial energy businesses). This makes our motors particularly suitable for the special service conditions of the basic materials industry or refineries. These motor types are labeled with VIK on the rating plate.Note Standards Country Title International IEC -...

Explosion Protection Types of Electrical Machines Explosion protection Protection type letter symbol Construction requirements Protection concept Application of type of electrical machine All potential ignition sources are housed inside a flameproof enclosure whose unavoidable sealing surfaces are therefore designed as flameproof joints, so that, in case of ignition of an explosive atmosphere inside the enclosure, the explosive atmosphere is not transferred to the potentially explosive atmosphere surrounding the enclosure. ! squirrel-cage motors ! slipring motors ! commutator motors. For...

11 Explosion protection of flameproof motors The motors have been tested and certified in accordance with the new European Directive 94/9/ EC (ATEX) by the German Federal Institute of Physics and Metrology (PTB). They therefore comply with the latest European regulations. The directive regulates the type of devices and protective systems suitable for use in hazardous areas and has been applicable throughout Europe for the marketing of this equipment since 30 June 2003. IECEx scheme certifications are available for all motors for international applications. The three-phase motors of the...

Explosion protection and categories of electrical machines Protection against dust entry acc. to EN 60079-31 Equipment-group Conductive dust IIIC Non-conductive dust IIIB Lint IIIA Dust explosion protection Dust-explosion-protected motors are certified by PTB according to the new Directive 94/9/EC and meet EN 60079-31. A significant feature of the dust explosion protection is the IP protection type. Depending on environmental conditions, different requirements are placed on the dust sealing of the motor. The limitation of the surface temperature of the motors to a value which is below the...

13 Permissible temperatures for electrical equipment The external CE mark and the device group specified on the rating plate, such as ”II 2G” for Zone 1 apparatus in explosive atmospheres consisting of gases, indicate that the motors are compliant with the requirements of the new directive. The affixing of the CE mark and the issuing of the relevant declaration of conformity by the manufacturer are subject to the following requirements: ! The manufacturer must have a certified quality assurance system in accordance with ISO 9000, with an additional certificate for quality assurance in the...
