YRKK Wound Rotor Induction Motor High-Voltage Three-Phase
Asynchronous Motors
Product overview
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, and the
bearing structure is designed according to IP54 and IP64. H355～630
adopts grease lubrication, H710～1000 adopts sliding bearing forced
thin oil lubrication.
The structure and installation type of this series of motors are
IMB3, the ratings are 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 significance of the 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 355 mm, and
the length of the No. 2 iron core
"4" indicates the number of poles
3. The power level, installation size and electrical performance of
YRKK series motors conform to the industry standard JB/T7594
"Technical Conditions for YR Series High Voltage Wound Rotor
Three-phase Asynchronous Motors" and other relevant standards, and
their installation dimensions and power levels also comply with
IEC72-2 standard requirement.
The cooling methods of YRKK series motors are IC01, IC81W and IC611
according to the standards of GB1993 and IEC34-6 "Motor Cooling
Methods"; the installation method of this series of motors is
horizontal foot installation (!MB3) structure, in line with GB997
and IEC34 -7 Regulations of "Motor Structure and Installation Type
Code". If the user has other requirements, it can be negotiated
separately.
