1.Adopt the integral structure, simplify the processing and assembly process.

2.Optimize the horizontal layout structure and connect the drive shaft directly.

3.Optimization of oil circuit design, reasonable distribution of oil injection between stages, more energy saving.

4.The motor is made of the special material of rare-earth permanent magnet,strong magnetic field,large overload torque and small current while staring and operation.

The special rare-earth permanent magnet with special design of the rotor,make the efficiency of the motor 10%-15% higher than the same horsepower induction motor.

Design of the lower temperature,the raise temperature of the motor ＜60K,greatly improves the service life and service factor.

Soft starter by the inveter,avoiding the strong mechanical shock while starting,prolonging the life of machine,reducing the maintenance,improving the reliability.
