YE3/YE4 Series three-phase asynchronous electric motor is developed as a new design of our company based on the characteristics of water pumps. YE3/YE4 Series motor with unique appearance, IP55 protection degree, class F insulation, and a good function of energy saving can reach high efficiency class in line with international standard IE2 and Chinese standard efficiency class 2, 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.
In order to solve problems like high torque, vibration, and noise in pumps, we uThe se cast iron material for all front flange and rear endshield in our new JLP motor, and this improvement can completely meet the application of various types of pumps.
