1、The IE4 efficiency in the IEC60034-30-1.2014 standard is the ultra-high efficiency achieved by squirrel-cage motors, and the price is now in a reasonable range.

2、In fact, the best solution to improve the efficiency of existing industrial applications is to directly replace high-efficiency new motors. But why aren't IE4 motors widely used yet? Some people may say that it is because IE4 motors are more expensive than IE2 motors and IE3 motors.

3、In fact, this kind of thinking is not wrong, but in the life cycle of the motor, the purchase cost only accounts for 1% of the maintenance and energy consumption costs. In fact, using IE4 motors can help customers save more costs.

4、High-efficiency motors increase efficiency in the industrial sector while reducing CO2 emissions.    

5、For example, according to the guidelines of the International Energy Agency (IEA), 504kg of CO2 can be released per 1,000KWh, then compared with the IE1 standard efficiency motor, a 3KW IE3 ultra-efficient motor can reduce about 1,000kg of CO2 per year, And a 250KW IE3 ultra-high-efficiency motor can reduce 25,000kg.

6、The W21 series of high-efficiency motors can meet different industrial applications and needs.
