Structural characteristics
This series motors with box type steel structure, can be observed its interior after removing the cooler or protective cover,
and esay to be installed and maintained; Rotor and stator are all made from low loss and high magnetic conductivity silicon steel;
The cage structure rotor made by once forming process or copper strip rotor made by mid-frequency welding process, improve the reliability of the motor; Insulation class F stator made by VPI process, ensure the reliability of insulation, moisture-proof and shock resistance; Temperature senor for stator and bearing, non-stop oil filling pipe and oil exit pipe, improve the protection ability and
operation efficiency of the motors.
