Hannover Messe Hall 15, as F11
WEG extends its W22X series of explosion-proof motors with the IEC size 800 for medium and high voltage applications. A special fair model of the currently largest engine in this series offers power ratings up to 5,6 MW and for voltages up to 11 kV. The W22X 800 has a four-pin version. At full load and a voltage of 6,6 kV it has an efficiency of 97,4%. Also on display will be the special motors of the subsidiary Antriebstechnik Katt, including the ultra-compact water-cooled motor series for outputs up to 440 kW.
With its high efficiency, the W22X 800 is also suitable for use in explosion-proof areas. This high efficiency is achieved, among other things, by a special tube cooling made of stainless steel to optimize the air flow. The motors are designed in a rigid steel housing and are available in 2, 4, 6 and 8 poles at frequencies of 50 and 60 Hz. Contrary to the usual strategy of designing large engines as project-oriented custom-made products, the W22X 800 was designed as a series engine with numerous optional modules. He currently holds the Atex and IEC Ex certifications for the area Ex d (e) IIB T4 Gb - more will follow. The combination of ruggedness and low maintenance makes the W22X 800 a perfect engine for energy-intensive applications with demanding environmental conditions, especially in oil and gas and mining.
Thanks to their cooling system, the ultra-compact, water-cooled motors from KATT achieve 1,5 to 2,6 times higher power density than conventional water jacket cooled motors. They are extremely compact in size, which in comparison to conventional water-cooled motors can often save several sizes while maintaining the same performance. By comparison, a conventional water jacket cooled motor with 300 kW in 315 size corresponds to an ultra-compact Katt 180 motor.
