Y,YR series,YKK,YKS,YRKK,YRKS series medium sized high voltage
three-phases asynchronous motors (shaft height *******0mm) 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 GB**5
(Fundamental Technical Requirements For Rotation Electrical
Machines), IEC Standards and Enterprise Standard of Mechanical and
Electronic Industries Department JB/DQ***4, JB/DQ***5, JB/DQ***6
and JB/DQ***7.
The mechanical dimensions and tolerances of this series of motors
conform with the China national standard GB l*******4 and the ISO
standard.
In respect to enclosure protection degree, the motor of these
series are of IP*3 and IP*4 of GB***2.1 and IEC***5 (Classification
of Enclosure Protection of Electrical Machines). Motors of
drip-proof IP*3 can be modified to motors of pipe ventilation IP*4
upon request of customer requests. Other protection degree such as
IP*4 and IP*4 are also possible by separate agreement if customer
requests .
In respect to type of cooling, the motors of these series are of
IC*1 , IC**1 and IC*1W of China National Standard GB***3 and
IEC***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 GB**7 and
IEC***7 (Construction and Code for Type of Mounting of Electrical
Machines).
