The differentiated design of the main and secondary shaft diameters in the product series significantly improves energy efficiency;
The fixed structure of the main bearing effectively reduces the variation in the clearance between the three spot welded pump body of the main housing;
Flat cylinder design effectively reduces gas leakage;
The lowest oil discharge volume in the industry;
Unbalanced design of the upper and lower end rings of the rotor, optimization of the balance block specifications, effectively reducing vibration noise;
The motor is miniaturized and serialized, adopting a large and small slot design, optimizing the arrangement of the main and auxiliary windings, improving slot utilization, and thus enhancing motor efficiency.
