The difference between YX3 high efficiency motor and YE3 high efficiency motor
Motor development
1996 stereotype Y2 series motor
Stereotype Y3 series motor in 2003
In 2002, in order to replace the Y2 motor, a Y3 series motor with cold-rolled silicon steel for hot-rolled silicon steel was designed. This series of motors adopts cold-rolled silicon steel, and the whole series basically meets the GB18163 energy efficiency limit standard.
High efficiency motor in 2005---YX3 series motor
Starting from the energy situation, energy saving and emission reduction and the development of the world motor industry, the small and medium-sized motor industry began to develop high-efficiency motors that meet the energy-saving evaluation value of GB18163, that is, China's Class 2 standard. Improvements in magnetic material selection, film research, ventilation improvement, etc. The efficiency increased by an average of 2.76%. Long-term continuous load can save a lot of electricity bills.
2010 ultra-efficient motor---YE3 motor
In response to the United States in 2011, the world will be the first to force the implementation of ultra-high efficiency standard motors, the domestic Shanghai Electric Research Institute led the development of ultra-efficient motor series products. This motor loss value is reduced by 20% compared to high efficiency motors. For motors with an annual running time of more than 8,000 hours, the load rate is over 60%, the electricity bill is calculated at 0.7 yuan/kWh, and the additional cost of the standard motor can be recovered in about 1.5 years.
Motor energy consumption standard
According to the new motor energy efficiency standards promulgated by the state in 2012:
GB18613-2012 "Small and medium-sized asynchronous three-phase motor energy efficiency limit value and energy efficiency rating"
YX3 series motor is an efficient 3-stage energy-consuming motor
YE3 series motors are ultra-efficient 2-stage energy-consuming motors
