Product Description

YRKK heavy duty high voltage slip ring ball re-rolling mill large size asynchronous ac electric Three phase Induction motor
slip ring motor YRKK Feature and usage:
Y,YR series,YKK,YKS,YRKK,YRKS series medium sized high voltage three phases asynchronous motors (shaft height 355-1000mm) are our optimized product series adopted the technical standard of high voltage three-phases asynchronous motors introduced from ABB and established on the basis of our experience of manufacturing high voltage motors, for upgrading the old JS,JSQ,JR and JRQ series.
These series motors adopt fine materials, excellent workmanship and features low operation cost, low noise, low vibration, high reliability and convenience for installation and maintenance.
The motors of these series meet the National Standard GB755 (Fundamental Technical Requirements For Rotation Electrical Machines), IEC Standards and Enterprise Standard of Mechanical and Electronic Industries Department JB/DQ3134, JB/DQ3135, JB/DQ3436 and JB/DQ3437.
The mechanical dimensions and tolerances of this series of motors conform with the China national standard GB l800-1804 and the ISO standard.

The high-quality slip ring motor is a sliding wrap-around three-phase asynchronous motor that can increase the starting torque at a small starting current. The motor is suitable for applications where the capacity of the feeder line is insufficient to start the squirrel-cage rotor, the starting time is long, the starting is frequent, and the small-range speed regulation is required. This series of motors has the advantages of high efficiency, energy saving, low noise, low vibration, light weight, reliable performance, convenient installation and maintenance.
