BN - BE - BX series - Three-phase asynchronous motors IE1-IE2-IE3 - 5

INTRODUCTION Efficiency classes and test methods Efficiency classes characterise the efficiency with which an electric motor converts electrical energy into mechanical energy. In Europe, the energy efficiency of low voltage electric motors used to be classified using the voluntary Eff1/Eff2/Eff3 system. Outside Europe, other countries used to apply their own national systems, often very different to the European system. This uncertainty in standards led manufacturers to develop a harmonised international standard, and push for the issue of IEC (International Electrotechnical Commission)...

BN - BE - BX series - Three-phase asynchronous motors IE1-IE2-IE3 - 6

European Commission regulation 640/2009 IEC standard 60034-30-1 establishes technical guidelines for efficiency classification but does not impose any legal requirements for the adoption of any particular efficiency class. These are laid down by European Directives and national laws. The EC Regulation applying Directive 2005/32/EC was adopted on the 22nd July 2009. This establishes the legal requirements and eco-compatible design criteria for electric motors, and imposes minimum efficiency limits according to the following schedule: ▪ 16/06/2011: Electric motors must have a minimum...

BN - BE - BX series - Three-phase asynchronous motors IE1-IE2-IE3 - 7

The asynchronous three-phase electric motors BX, BE, BN of BONFIGLIOLI RIDUTTORI’s production, are available in basic designs IMB3, IMB5 and IMB14 and derived versions. Motors are the enclosed type with outer fan and cage-tipe rotor for use in industrial environments. Standard versions of BX/BE motors are 230/400V A/Y (400/690V A/Y in sizes BX/BE 160 and BX/ BE 180), 50 Hz motors, with a tolerance of ±10%. Standard BN motors are designed to operate from a rated voltage 230/400V A/Y (400/690V A/Y for frame sizes BN 160 through BN 200) 50 Hz, with ±10% tolerance. 3.2 Standards The motors...

BN - BE - BX series - Three-phase asynchronous motors IE1-IE2-IE3 - 8

BX, BE, BN motors meet the requirements of Directives 2006/95/EC (Low Voltage Directive) and 2004/108/EC (Electromagnetic Compatibility Directive) and their name plates bear the CE mark. As for the EMC Directive, construction is in accordance with standards CEI EN 60034-1, EN 610006-2, EN 61000-6-4. Motors with FD brakes, when fitted with the suitable capacitive filter at rectifier input (option CF), meet the emission limits required by Standard EN 61000-6-3:2007 “Electromagnetic compatibility -Generic Emission Standard - Part 6-3 Residential, commercial and light industrial...

Flange output motors are also available with reduced coupling dimensions, as indicated in the table below - executions B5R, B14R. (1) flange with through holes (2) flange with threaded holes The following chart provides an overview of the degrees of protection available. In addition to the degree of protection specified when ordering, motors to be installed outdoors require protection against direct sunlight and also - when they are to be installed vertically down - a drip cover to prevent the ingress of water and solid particles (option RC).
