DESCRIPTION OF HI-EFFICIENT MOTOR
The newly developed YE3 and YE4 series are the three-phase asynchronous electric motors of high and extra-high efficiency, which are of lE3 and lE4 class efficiency respectively. Because of the innovated technology on rotors of the YE4 series and the compact construction caused by it, the YE4 series motors have same shaft center heights as the YE3 series motors. Customers can conveniently upgrade their motors to higher efficiency level without any mechanical modification to the driven machines. The convenience of upgrading is a deciding factor when users evaluate the possibility of upgrading. Normally, the initial increase of motors of higher efficiency can be paid back in less than two years by saving of energy expense. In long run terms, the motors of lE4 are not only energy saving but also cost effective.
Housings and end bells of cast iron, along with advanced aerodynamics design, provide improved cooling airflows. Improved designed housings provide high strength and rigidity.
With excellent quality, reliable operation, and compact structure, the YE3 and YE4 series three-phase asynchronous electric motors are appropriate drives for blowers, pumps, compressors, hoisters, centrifugal machines, rubber and plastic equipments, and etc. They are suitable for various applications, like chemical industry, petroleum and natural gas, cement, mining, paper mill, water handling/wastewater treatment, steel, and marine engineering. They always can provide superb power, no matter where they are installed, indoor, outdoor, or plateau regions, or where there is of humid climate.
