3 Phase TEFC Induction Motors

3 Phase TEFC Induction Motors

According to the National Standard energy efficiency rating determination and energy saving evaluation for small & medium sized three phase asynchronous electric motors, the efficiency classification of CEMP, Australian / New Zealand standard AS/NZS 1359.5 and some other equivalents in other countries, GT series class 2 and GT1 series class 1 with high efficiency are designed as the efficient energy products with our in-house strength. The efficiency rating of these products not only reaches but even exceeds the high efficiency benchmarks of other countries. GT series hi-efficiency motors cover a wide power range based on the motor with 380 V, 400 V, 50 Hz; S1 on 2P, 4P, 6P, 8P and frame size from 80 to 355. They aregenuine high efficiency energy saving products.

GT series three phase asynchronous electric motor was introduced as an updated design not only in conformity with IEC standard but also combining the design of Y series, Y2 series, and Y3 series of India and other standards of electric motors in European countries. It fully absorbs the advanced technology of electric motor in the world. GT series motors with IP 55 protection degree, class F insulation and good function of energy saving can reach high efficiency class in line with European EFF2. GT1 series with efficiency rating in accordance with European EFF1 are an ideal energy saving products. Moreover, it has other distinct features like high starting torque, low noise, optimum structure, unique appearance, convenient operation and so on.

GT series motors with the mounting dimension in accordance with IEC 60034 and DIN 42673 are identical to the mounting dimension of Indian Y series, Y2 series and Y3 series.

GT series motors can be widely used in various kinds of general use machineries like compressors, fans, pumps, machine tools, mills, transportation machines and so on. They can also be used in hazardous areas of oil, chemicals, steel plants, marine and mining industry.
