2. Guide to motor choice dpcm First step is the classification of hazardous places in zones. The end user shall classify the hazardous areas under his own responsibility. Directive 1999/92/EC provides information regarding 'Classification of places where explosive atmosphere may occur'. The corresponding standards of reference are EN 60079-10-1 for gas and EN 60079-10-2 for dust. Here below we give you a synthetic step by step guide to the choice of the motors. DUST group IIIC Conductive dust IIIB Non-conductive dust IIIA Combustible fibers (1) Group II Comprises equipment intended...

Motor characteristicsRange of motors dpfcm Ex Elprom motors are manufactured in compliance with all the European standards concerning equipment and protective systems for potentially explosive atmosphere in compliance with the European Directive ATEX 94/9/CE (better known as ATEX) and IECEx Scheme. Here below in the table we show you the range of motors for each type of protection. In the following pages we will talk about testing and certificates, main features of these motors and possible options always depending on the type of protection. (*) If provided of Thermal Protection (normally...

The dimensions of the motors comply with EN 50347 and IEC 60072-1, the mounting arrangements B3, B5, B14 comply with EN 60034-7. All the geometrical dimensions are unified according to the tables UNEL 13113-71; 13117-71; 13118- 7; IEC 60072-1. The IP degrees of protection of the motors comply with IEC/EN 60034-5 and EN 60259. Insulation class All the motors have an insulation class F in compliance with IEC/EN 60034-1. Insulation class H on request. The bearings are single raw deep grooves ball bearings, preloaded by a wave spring. Duty The motors are normally made for S1 duty; otherwise...

Main Options Axially locked shaft Motors with a locked bearing on the font shield using an elastic metal ring. This solution is necessary in case of alternative axial stress (ie. Bevel gear pinion with alternative load or motion, frequent start-up under load or with high inertia) so to create axial movement of the shaft and bumps on the bearings. Low temperatures motors (-40 °C) They have to be fitted with special bearing, metallic fan, metallic cable gland and plugs or made with special plastic materials. In these cases, if there is a risk of condensation, it is better to fit the motors...

4. Terminal box, cable entries and connections dpnm As the feet can be mounted on the frame, it is possible to fix them in 3 different positions so to have the possibility to have the terminal box on the top or on the right and left sides of the motor (see picture 1). At the same time the terminal box can be mounted on the motor so to have the cable entries where it is necessary. So the cable entries can be in the four different positions (see picture 2). Motor size Cable connection on the terminal board Motors 'Ex de' (only ATEX approved) The flameproof motors with increased safety...

dpfcm Motor size The motors are normally fitted with permanently greased bearings of type 2Z, lubricated with a special grease G-15 and have a service max temperature of 150°C. The bearing life time for aluminium motors is approximately (depending on application and load conditions): • 2 and 2/4 pole motors, 10 000 - 20 000 duty hours • 4 to 8 pole motors, 20 000 - 40 000 duty hours Both on drive end and non-drive end are mounted V-ring seals in order to have the IP66 protection. 5.1 Permissible radial and axial forces on the shaft end The following tables give the permissible radial and...
