IE3. IE4 three-phase asynchronous motors is developed as a new design of our company based on the characteristics of water pumps. This series of motors with a unique appearance, IP55 protection degree, class F insulation. and a good function of energy saving can reach high-efficiency class in line with international standards IE3, IE4, and China's GB3 & GB2, which has made it an ideal energy saving product. Moreover, it has other good features like high starting torque, slight noise, low vibration, optimum structure, convenient operation, and so on. To solve problems like high torque, vibration, and noise in pumps, we use cast iron material for all front flanges this improvement can completely meet the application of various rear end shield in our IE3, IE4 motors, and types of pumps.
