IEC-Короткозамкнутуе электродвигатели - новая версия 1LE1
Increasing energy costs have resulted in greater emphasis on the power consumption of drive systems. It is extremely important to utilize the full potential for minimization here to secure competitiveness today and in the future. This is the reason that already today, Siemens is developing a new generation of low-voltage motors. Innovative copper rotors create the best requisites for motors with high efficiencies. The new motors for EFF1 (High Efficiency) offer considerable energy savings and protect our environment. The table shows an overview of the technical features of these motors. The presently available product range with ordering data, technical data and detailed explanations are provided in the new Catalog News D 81.1 N “Low-Voltage Motors – IEC Squirrel-Cage Motors – New Generation 1LE1 – Frame Size 100 to 160” and on the Internet under: http://www.siemens.com/motors
