Features and advantages

1) Optimized electromagnetic design

This series of motors use finite element method to analyze electromagnetic performance, heating, mechanical stress and deformation; and the motors’ dimensions have been reasonably matched and performance has been maximized to the highest level through comprehensively optimizing not only electromagnetic design, but also dimensions, air gap and slot combination and shape.

2) Low harmonic winding

Low harmonic winding are adopted in this series of motors, which can reduce stator copper loss and stray loss, thus enhance operation efficiency.

3) High-strength magnetic slot wedge

It takes a long period of research for Motor Division to solve dropping out of slot wedge and improve the motor electrical performance by employing high-strength magnetic slot wedge and adopting a mature and stable slot wedge fastening process and materials

4) Optimized ventilation cooling system

The motors use backward centrifugal fans, axial flow fans etc., which can maximize internal and external ventilation system, improve cooling effect, reduce ventilation loss (esp. for high-speed motor), lower ventilation noise and enhance efficiency.

5) Insulation system

This series of motors adopt an insulation system with various performances comprehensively improved; voltage characteristics,

temperature characteristics, bending strength, breakdown voltage test, heat and electrical aging tests all prove that this series insulation system has achieved world-class level. The motors are excellent in insulation performance, mechanical strength and moisture resistance, since high-quality mica tape and environment-friendly impregnating resin are adopted,
