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.
