YRKK series (H355~1120) 6KV, 10KV high-voltage three-phase
asynchronous motors are wound rotor asynchronous motors. The
protection level of this series of motors is IP44 or IP54, and the
cooling method is IC611, IC616, IC666 (see GB/T1993).
This series of motors has the advantages of high efficiency, energy
saving, low noise, low vibration, light weight, reliable
performance, convenient installation and maintenance, etc.
This series of motors can provide increased starting torque under a
small starting current, and can adjust the speed within a certain
range. It is suitable for: the capacity of the feeder circuit is
not enough to start the squirrel-cage rotor motor; the starting
time is long and the starting time is too long. More frequent;
occasions where a small range of speed regulation is required. Such
as: drag winch, rolling mill, wire drawing machine, etc.
This series of motors adopts F-class insulation structure. The
bearing structure is designed according to IP54 and IP64. H355~630
adopts grease lubrication, and H710~1000 adopts sliding bearing
forced thin oil lubrication.
The structure and installation type of this series of motors are
IMB3, the rating is based on continuous duty (S1), the rated
frequency of the motor is 50Hz, and the rated voltage is 6KV and
10KV. Agreed with the user.
Second, the meaning of YRKK high voltage motor model
Example: YRKK 3552-4
"YRKK" means enclosed wound rotor asynchronous motor with
air-to-air cooler
"3552" indicates that the center height of the base is 355mm, and
the No. 2 iron core is long; "4" indicates the number of poles
