Model Description of Simo's YRKS Series Wound - Rotor Air - Water - Cooled High - Voltage Motors in Xi'an

Taking the YRKS7101 - 4 of Simo's YRKS series 6 - kV wound - rotor air - water - cooled high - voltage motors in Xi'an as an example: YRKS represents a wound - rotor three - phase asynchronous motor with a closed air - water cooler; 7101 indicates that the center height of the machine base is 710 mm and the length of the iron core is No. 1; 4 represents that the number of poles of the motor is 4.

The YRKS three - phase asynchronous motor (with a center height ranging from 710 to 1000) 10KV series is a wound - rotor three - phase asynchronous motor. This three - phase asynchronous motor is produced in accordance with the technical conditions of JB/T7594 - 1994. The 10KV motor can be directly applied to the 10KV power grid, which simplifies equipment, saves investment, and reduces energy consumption. The protection level of the YRKS series motors is either IP44 or IP54, and the cooling method is ICW81A. The stator winding uses Class F insulation materials and is firmly fixed and bound at the bottom. During the manufacturing process, it undergoes multiple inter - turn impulse voltage tests and withstand voltage tests to the ground, and is processed using the imported advanced vacuum pressure impregnation solvent - free paint process (VPI). As a result, the motor has excellent and reliable insulation performance, good mechanical strength, and strong moisture - proof capabilities.
The rotor winding is made of pure copper and adopts Class F insulation materials.
There are two types of bearings, namely rolling bearings and sliding bearings, which are determined according to the motor power and speed. The rated voltages are 6KV and 10KV, the rated frequency is 50Hz, and the basic protection level is IP44. Motors with other voltages, frequencies, and protection levels can also be provided as per the order requirements.
The YRKS series motors feature high efficiency, energy conservation, low noise, small vibration, light weight, reliable performance, and convenient installation and maintenance.
The Xi'an Simo YRKS series wound - rotor air - water - cooled high - voltage motors can provide a large starting torque with a small starting current. They are suitable for situations where the capacity of the feeder line is insufficient to start a squirrel - cage rotor motor, the starting time is long, the starting is relatively frequent, or a small - range speed regulation is required. For example, they can be used to drive winches, rolling mills, wire - drawing machines, etc.
The YRKS series motors adopt a box - type structure with Class F insulation and an installation type of IMB3. They have a continuous rating based on the continuous duty system (S1). The H710 - 800 motors use a sliding - bearing structure. The rated frequency of the motor is 50HZ, and the rated voltages are 6KV and 10KV. For other voltage levels or special requirements, they can be negotiated with the manufacturer when placing an order.

In order to improve the quality of various electromechanical products, strengthen pre - sales and after - sales services, and ensure customer satisfaction, Simo Motor resolutely implements the "Quality Assurance Statement" of eight scientific research and design institutes in the machine tool industry of the Ministry of Machinery Industry. It earnestly implements all the clauses in the statement and strictly adheres to the rules and regulations of the ISO9001:2000 quality management system to ensure:

Motor model (YRKS7101 - 4) Installation method (IMB3)
Rated power (2800KW) Protection level (P44 or IP54)
Rated voltage (6000V) Cooling method (IC01)
Rated frequency (50Hz) Insulation class (Class F)
