Lenze M5**P****04******

The register lists here 33 versions with 0.75 to 55 kW, two- or four-pole, at a supply voltage of 400 V. Efficiency at full load ranges from 80.5 to 94.6%, and at 75% load from 78.58 to 94%. Frame sizes run from 80 to 250, enclosure ratings from IP54 to IP66. Manufacturing takes place, depending on the model, in China or in a combination of several countries, including Italy, Germany, France, Austria, India and the United States. For 31 of the 33 motors the High Efficiency Level classification is documented: 17 reach the 2018 level, 13 carry no classification, one the 2005 level.

The page thus shows Lenze's international manufacturing network in the power band up to 55 kW, with high enclosure ratings up to IP66 for use in demanding environments such as wet areas or dusty industrial atmospheres; a substantial part of the range already reaches the newer 2018 High Efficiency classification.

When buying used, check the condition of the rolling bearings, a measured winding insulation resistance, the condition of the shaft seals on the higher enclosure ratings, and a legible nameplate showing frame size, pole count and efficiency class. Since Lenze motors are often combined with frequency inverters, it is also worth checking inverter suitability; spares run through the Lenze sales network.
