YRKK series slip-ring AC induction electric motors

pole:4,6,8,10,12,16,20,24  IP23~55,insul:B~F

voltage: 10kv,6kv,3kv,380v  power:250~10000kw

Y, YR series are the basic series, Protection degree is IP23, protective cover and its cover plate removed and the base at the top and side of the roof to install a different cover and cover can be formed of different protective methods and cooling method motors.  The use of sliding-type stator fitted the structure of external pressure. Stator using  material  of insulation F, at the end there is a reliable fixed and banding, in the manufacturing process after several turn-to-turn impulse voltage test and the voltage-to-ground tests, and using vacuum pressure impregnation process solvent-free paint (VPI) treatment. Therefore, the electrical equipments have very good insulation performance and reliable mechanical strength, and moisture-proof ability.  Squirrel-cage rotor use reliable and advanced welding technology, and by the bed fastening process. Wound Rotor using  the materials of insulation degree F and using vacuum pressure impregnation materials and solvent-free process (VPI) treatment, welding rotor head and wiring all be insulated to ensure that there is reliable.  there are two type of :Bearings rolling bearings and sliding bearings .this is according to motor size and speed of moving.the basic forms of protection degree is IP44, if motor have higher protection degree, the bearings also have higher  protection degree.  the protection degree for the main outlet Box is IP54 , it is usually at the  right side (viewing from the shaft  extension side ). but it can also be  be installed at the  left side )as the  requirements of orders. there are terminal to the ground both inside and outside of the main outlet box.
