Introduction
YE3-80~355 (IP54~IP55) series high-efficiency low-voltage three-phase asynchronous motors adopt high-strength cast iron structure, with the advantages of high efficiency, high reliability, low noise, beautiful appearance, low noise, high torque, good starting performance, compact structure, easy use and maintenance, etc. Its efficiency fully meets the requirements of Class 3 energy efficiency in GB18613-2020 “Energy Efficiency Limit Values and Energy Efficiency Grades for Small and Medium-sized Three-phase Asynchronous Motors”, and has passed the energy-saving product certification of the China Quality Certification Center.
Application fields
Suitable for industrial fields that require energy saving and continuous operation, such as fans, water pumps, compressors, crushers and engineering machinery. It can also be used as a power source in petroleum, chemical, pharmaceutical, mining and other places with relatively harsh environmental conditions.
Features
The power level, electrical performance, installation dimensions and tolerances of this series of motors are in compliance with the national standard GB755 “Ratings and Performance of Rotating Motors”, the International Electrotechnical Commission standard IEC34-1 “Ratings and Performance of Rotating Motors” and the mechanical industry standard GB/T 47721. The enclosure protection level of this series of motors is IP54 and IP55 according to the standards of GB4942.1 and IEC34-5 “Ratings and Performance of Rotating Motor Enclosures”. The cooling method of this series of motors is IC411 according to the standards of GB/T1993 and IEC34-6 “Cooling Methods of Rotating Motors”. Our company adopts H-class insulation for this series of motors, and the temperature rise of the whole series is assessed according to B-class, which greatly improves safety and reliability.
