Difference between YX3 high efficiency motor and YE2 high efficiency motor
YX3 high efficiency motor is the first high efficiency electric machine with cold rolled silicon steel as the guide material in the country. Is designed and developed on the basis of Y3 motor, Y3 motor is the first one to the design of cold rolled silicon steel as the guide magnetic material of the general motor, is the country "to cold generation hot" products.
YX3 high efficiency motor is the first high efficiency electric machine with cold rolled silicon steel as the guide material in the country. Is designed and developed on the basis of Y3 motor, Y3 motor is the first one to the design of cold rolled silicon steel as the guide magnetic material of the general motor, is the country "to cold generation hot" products. YX3 motor design in September 2005, 2003 by the mechanical association of the identification of the organization. The main performance indicators in line with the GB/T18613-2002 version of the 2 energy efficiency standards - that is, the value of energy-saving evaluation. Is also in line with the requirements of the European EFF1 index. Later GB/T18613-2006 version of the evaluation of the value of energy, but also to achieve. Its detection method for the motor of the stray loss, the input power of 0.5% to calculate, design is also based on the calculation of electromagnetic data. Domestic motor manufacturers in 2008 before the 2 level of energy efficiency for the record, and energy-saving product certification, in addition to the joint venture brands, are using YX3 motor. So as an efficient motor, YX3 motor is widely known in China.
In 2008, NEMA and IEC in the United States through negotiations, the high efficiency of the motor indicators and testing methods to do a unified, developed a new energy efficiency indicators and detection methods. The biggest difference is that the index value of the high efficiency motor is lower than that of the IE2 value, but the detection method of the motor adopts low uncertainty detection method, the biggest difference is that the stray loss of the motor is measured by the method. This and YX3 design is somewhat different, faced with the adjustment of indicators, there is no corresponding IE3 indicators of the motor.
Thus, Shanghai Electrical Science Research Institute in 2009, dozens of motor factory organization in the motor motor industry, combined with the design with IE2 motor, IE3 index. IE2 motor on the basis of YX3 efficient motor, to adjust the part of the design, in order to meet the requirements of IE2 indicators and detection methods, named YE2 series of high efficiency motors. This series is designed in 2011 by the machinery industry association of the organization identification. Motor according to the IE3 index, China had no reference sample, only NEMA ultra performance series, a few manufacturers are doing so on the basis of the development of the domestic motor to meet the requirements of IE3, named YE3 series ultra efficient motors, this work ended in 2013.
Later revised version of the GB/T18613-2012, the IE2 index as the basic energy efficiency limit is 3 energy efficiency indicators, IE3 indicators as the evaluation of energy efficiency is the 2 level of energy efficiency indicators. That means that the YX3 series of motors with a slight adjustment, to achieve a new level of energy efficiency indicators, and YE2 is designed according to the requirements of the IE2 high efficiency motor. In the new standard, although the YX3 index value is slightly higher than the YE2 motor, but the detection method is different, in many specifications than the YE2 motor, the performance is similar, all belong to the new 3 level energy efficiency. These two series motors, in the new national standard, has not been a high efficiency motor. Now the domestic current Y, Y2, motor has been eliminated, but everyone said it was also said that YE2, YX3 is an efficient motor.
