當前位置：首頁 > YE2 SERIES HIGH EFFICIENCY THREE-PHASE INDUCTION M
The three-phase asynchronous motor of the YE2 series is in line with the third efficency standard in the prov isions of GB 18613-2012 "the energy efficiency limit and the energy efficiency rating of small and medium-sized three-phase asychronous motors ".And the improvement of the efficiency in its design is in line with the state's on the energy saving and consumpton reducing of the manufacturing sector.
YE2 series motors with the mounting dimension in accordance with standard IEC60034, t has good features like optimum structure,attractive appearance, low noise, high efficiency, high protection class as well as high insulation class. YE2 series motors can be widely used in various kinds of general use machineries ike fans, pumps, machin tools,compressors, transportation and so on, and can also be used in the hazardous areas with oil and chemical, steel plants, mining industry
YE2 series motors air suitable for almost all applications and operate satisfactorily at temperatures from-20 °C to+40°C and altitudes up to 1000 meters above sea level.
Temperature and insulation
The Motors insulation system are designed by Class F(155°C), operated with Class B(80K).Which incerase the motor useful life and reliability.
Cooling and ventilation
The standard cooling method is totally Enclosed Fan Cooled(TEFC)in accordance with IC411 of IEC60034-6. Standard motors are equipped with radialflow plastic fans.
The standard degrees of protection is IP55. The IP55 enclosure means complete hoseproof and dustproof protection, A higher degrees of protection is available.
Motors can be installed with PTC, PT100, such as winding and bearing temperature measurement as well as other kinds of protec-tion on request.
Voltage and frequency
Standard voltage and frequency are 380V 50HZ, and can be wound for any single voltage in the range 200-660V at a frequency 50. The motors will operate satisfactorily with variations of ±5% from the rated voltage.
YE2 motors are designed to vibration class A, vibration class B is available on request.
Terminal box location
Terminal box at the top or right of frame is the standard YE2 motor.
Stringent quality procedures are observed from first design to finished products in accordance with ISO9001 documented quality systems.
Motor working system
This series of motors working system for S1 continuous duty.
