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.
In respect to enclosure protection degree, the motor of these series are of IP23 and IP44 of GB4942.1 and IEC34-5 (Classification of Enclosure Protection of Electrical Machines). Motors of drip-proof IP23 can be modified to motors of pipe ventilation IP44 upon request of customer requests. Other protection degree such as IP24 and IP54 are also possible by separate agreement if customer requests.
In respect to type of cooling, the motors of these series are of IC01, IC611 and IC81W of China National Standard GB1993 and IEC34-6 (Type of Cooling of Electrical Machines). Other type of cooling are also possible by separate agreement if customer requests.
In respect to type of mounting the motors of these series are of IMB3 horizontal with feet, satisfying the requirements of GB997 and IEC34-7 (Construction and Code for Type of Mounting of Electrical Machines).
