Product Desciption
The 6KV/10KV motor series YRKK (center height 355-1,000) is a kind of 3-phase wound-rotor asynchronous motor produced in line with technical specifications in JB/T T10314.2-2002, with a protection class IP44 or IP54 and a cooling mode IC611.
The series YRKK has many advantages, such as high efficiency, energy conservation, low noise, slight vibration, light weight, reliable performance and installation & maintenance convenience.
Series YRKK can offer a big starting torque even under a small starting current; but its feeder line capacity is not big enough to start squirrel-cage rotor motor; its starting time is long and it needs frequent starting; and it is suitable for cases needed for small-range speed adjustment, e.g., to drive winch, rolling mill and drawbench.
This series YRKK has a structuring and mounting mode IMB3, whose ratings mean the values based on continuous duty (S1), rated frequency 50 HZ, rated voltage 6KV/10KV; for other voltage classes or special requirements could be discussed separately.
The motor uses box-type structure. The frame is made of steel sheet welding, featured with light weight and fair rigidity. Enclosed air cooler is mounted at top of motor, featured as convenient reassembling and favorable for maintenance and repair of motor. The slip-ring cover has viewing window to observe operating condition.
The stator uses external press fitting structure. The stator winding uses Class F insulation material. The end has reliable fixing and binding. Multiple inter-turn impulse voltage tests and grounding high-voltage holding tests have been conducted in manufacturing procedure. And it is processed with internationally advanced vacuum pressure impregnation (VPI) solvent free varnish equipment and process. Thus the motor has excellent and reliable insulating property, fair mechanical strength and strong moisture-proof capacity.

Wound rotor uses Class F insulation material.
The bearings have antifriction bearings and sliding bearings to be determined by power and rotating speed of motor. The rated power frequency of motor is 50 Hz, rated voltage as 6000 V, and primary type of protection grade as IP44. According to negotiation, the enclosure protection grade of collecting ring may be IP22 or IP23. We can also provide motors of other voltage, frequency protection grade as per ordering requirements.

The large high-voltage wound rotor slip ring motor can increase the large starting torque at a small starting current. The motor is suitable for applications where the capacity of the feeder line is insufficient to start the squirrel-cage rotor, the starting time is long, the starting is frequent, and the small-range speed regulation is required. This series of motors has the advantages of high efficiency, energy saving, low noise, low vibration, light weight, reliable performance, convenient installation and maintenance.
Main process flow of the motor
Motor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage
The company has large-scale laboratory, intelligent CNC winding machine, CNC rising machine, automatic wrapping machine, VPI high pressure vacuum immersion system, large-scale dipping paint drying furnace, 60 tons test platform, large vertical car, milling machine, grinding machine, Each type of dynamic balancing machine, double-feedback test and detection system with 6MW (12MW) motor and other motor production professional equipment more than 500 sets, sound mechanical equipment processing capacity, to lay a good foundation for customers to improve good quality motor products.
1. The outer packaging of the products are all standard export-oriented wooden plywood packaging.
