YRKK YRKS Wound Rotor Induction Motor High-Voltage Three-Phase Asynchronous Motors

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, 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.

YRKS high-voltage motor winding rotor adopts F-class insulation material. There are two types of bearings: rolling bearings and sliding bearings, depending on the power and speed of the motor. YR series is the basic series, and the protection level is IP54. YRQF series (IPW24) and YRKS series (IP44 or IP54) can also be derived according to the ordering requirements.
The main junction box is generally installed on the right side of the motor (viewed from the shaft extension end), and can also be installed on the left side of the motor according to the ordering requirements. There is a separate ground terminal in the main junction box.

YRKS high-voltage motors can be used to drive various general machinery such as compressors, water pumps, crushers, cutting machine tools, transportation machinery and other mechanical equipment, and are used as prime movers in various industrial and mining enterprises such as mining, machinery industry, petrochemical industry, and power plants. use. Motors used to drive blowers, coal mills, rolling mills, and hoists should indicate their use and technical requirements when ordering, and adopt special designs to ensure reliable operation.
