Cb, Ot, Mub, Mb, FFB Electromechanical Manual General information Directives and standards relating to motor efficiency There have been a number of changes to the standards and new standards created in recent years. They mainly concern motor efficiency and their scope includes measurement methods and motor classification. Regulations are gradually being implemented, both nationally and internationally, in many countries in order to promote the use of high- efficiency motors (Europe, USA, Canada, Brazil, Australia, New Zealand, Korea, China, Israel, etc.). The new generation of Premium efficiency...

Electromechanical Manual Environmental limitations In temperate climates, relative humidity is generally between 50 and 70%. For the relationship between relative humidity and motor impregnation, especially where humidity and temperature are high, see table on next page. g / m3 40 Measuring the humidity: Humidity is usually measured by the “wet and dry bulb thermometer” method. Absolute humidity, calculated from the readings taken on the two thermometers, can be determined using the chart on the right. The chart also provides relative humidity figures. To determine the humidity correctly, a good...

Cb, Ot, Mub, Mb, FFB Electromechanical Manual Environment Impregnation and enhanced protection NORMAL ATMOSPHERIC PRESSURE (750 MM HG) The selection table below can be used to find the method of manufacture best suited to particular environments in which temperature and relative humidity show large degrees of variation (see relative and absolute humidity calculation method, on preceding page). The symbols used refer to permutations of components, materials, impregnation methods and finishes (varnish or paint). The protection of the winding is generally described by the term "tropicalization". For...

However, electromagnetic emissions may be noticeably reduced by a special construction of aluminium alloy end shields and a stainless steel shaft. Immunity The construction of motor housings (especially finned aluminium alloy frames)isolatesexternalelectromagnetic sources to...

Electromechanical Manual Environment External finish Leroy-Somer geared motors and motors are protected with a range of surface finishes. The surfaces receive appropriate special treatments, as shown below. 1. Other finish: please call. * Values given for information only since the substrates vary in nature whereas the standard only takes account of steel substrates. ** Evaluation of the degree of rusting in accordance with ISO 4628 (rusted area between 1 and 0.5%). The Ia system applies to the group of moderate climates and the Ila system to the group of general climates, as defined in standard...
