YRKK High Voltage Squrriel Cage Induction Electric Motors  (Center height 355-630 m) are updated from old products JS, JSQ, JR and JRQ  series.
This series of motor may be used for driving all kinds of general machines such as the compressor,ventilation fan, water pump,  stock-removing machine, transportation machines and other mechanical equipment, and are applied as  the prime mover in all industrial and mining enterprises such as the mine, machinery, petrochemical industry and power  plant, etc.
This series of motors adopt excellent materials, manufacture sophisticated, with high force and energy indicators,low  noise and small vibration , high reliability and easy to  install and maintain .
This series of motor are  high power , large size , electrical performance are in line with the national standard GB755 "rotary motor basic technical requirements," IEC International Electrotechnical Committee standards and machinery and electronics industry enterprise standards JB/DQ3134, JB/DQ3135, JB/DQ3436 and JB / DQ3437.
Motor frame adopt the  box-type structure. adopt the use of steel plate welding machine into the box structure, light weight, good stiffness. Base on both sides of face and at the top have small holes, you can install the protective cover or lid. removed the protective cover or cover plate ,you can  touched upon the internal of motor,it is very convenient for maintenance and repair of motor.
