KTZ YE3 series (IEC frame size 71-315, 0.37-200kW) comprises of three-phase, Totally Enclosed Fan Cooled (TEFC), squirrel-cage asynchronous induction motor. This series of motors are designed based on international advocacy for energy conservation and environment protection. Categorized as a premium energy-efficient motor, its efficiency is on average, 3% higher than YE2 motors and 5% higher than Y2 motors, consistent with the IE3 standard in IEC 60034-30. Our usage of premium quality materials results in lower operating temperature, longer operational life and low maintenance costs. Our motors are designed to meet higher rotation speed under the rated load, in line with our future development vision.
