Yrkk Series Wound Rotor Slip Ring Large Size High Voltage Motor

The 6KV/10KV motor sequence YRKK (center peak 355-one,000) is a kind of three-period wound-rotor asynchronous motor developed in line with complex requirements in JB/T T1571.2-2002, with a defense class IP44 or IP54 and a cooling mode IC611.
The series YRKK has many rewards, these kinds of as higher effectiveness, vitality conservation, minimal sounds, slight vibration, light-weight bodyweight, reputable performance and set up & upkeep comfort.
Sequence YRKK can provide a large commencing torque even under a modest starting up current but its feeder line capability is not big ample to start squirrel-cage rotor motor its commencing time is extended and it requirements repeated starting up and it is ideal for instances needed for tiny-variety velocity adjustment, e.g., to drive winch, rolling mill and drawbench.
This collection YRKK has a structuring and mounting manner IMB3, whose rankings mean the values dependent on constant obligation (S1), rated frequency fifty HZ, rated voltage 6KV/10KV for other voltage lessons or special demands could be discussed independently.
The motor uses box-sort composition. The body is produced of metal sheet welding, showcased with light-weight weight and honest rigidity. Enclosed air cooler is mounted at best of motor, featured as practical reassembling and favorable for servicing and fix of motor. The slip-ring include has viewing window to notice functioning issue. 
The stator makes use of exterior push fitting composition. The stator winding uses Class F insulation substance. The end has reliable repairing and binding. Several inter-switch impulse voltage checks and grounding higher-voltage keeping assessments have been conducted in producing method. And it is processed with internationally superior vacuum pressure impregnation (VPI) solvent cost-free varnish equipment and procedure. Therefore the motor has outstanding and dependable insulating house, fair mechanical power and sturdy dampness-proof capacity.
The motor employs box-sort composition. The frame is produced of metal sheet welding, featured with light weight and fair rigidity. Enclosed air cooler is mounted at leading of motor, highlighted as handy reassembling and favorable for servicing and fix of motor. The slip-ring cover has viewing window to observe running problem. 
Wound rotor uses Class F insulation content. 
The bearings have antifriction bearings and sliding bearings to be determined by electricity and rotating speed of motor. The rated energy frequency of motor is fifty Hz, rated voltage as 6000 V, and main kind of safety quality as IP44. According to negotiation, the enclosure security grade of amassing ring could be IP22 or IP23. We can also provide motors of other voltage, frequency safety quality as per ordering requirements.
The bearings have antifriction bearings and sliding bearings to be identified by energy and rotating speed of motor. The rated power frequency of motor is 50 Hz, rated voltage as 6000 V, and major type of protection grade as IP44. In accordance to negotiation, the enclosure security grade of accumulating ring could be IP22 or IP23. We can also give motors of other voltage, frequency safety quality as per purchasing needs.
The motors can be employed to generate a variety of machines, e.g. compressor, pump, crushers, inventory-removing equipment, transport devices and other devices as key engines in different industrial and mining enterprises, e.g. mines, engineering industry, petrochemical sector and power plant. Goal and specialized specifications shall be indicated in purchasing motor for ventilating supporter, coal grinding mill, iron-rolling mill and hoister so as to use particular layout for trustworthy operation.

The huge high-voltage wound rotor slip ring motor can boost the massive starting torque at a modest beginning present. The motor is suitable for apps exactly where the capability of the feeder line is insufficient to start the squirrel-cage rotor, the starting time is long, the starting is regular, and the tiny-assortment pace regulation is required. This series of motors has the advantages of high effectiveness, energy preserving, low sound, minimal vibration, mild excess weight, dependable functionality, practical installation and upkeep.

Primary procedure movement of the motor
Motor stator: casing processing → punching press → iron main seating → coil creating → weaving → dipping paint drying
CZPTtronic rotor: blank shaft processing → iron core push set up → iron main cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic harmony
Motor assembly: stator rotor assembly → device check → motor appearance coloring → packaging storage

The organization has huge-scale laboratory, clever CNC winding machine, CNC growing device, automated wrapping machine, VPI substantial force vacuum immersion system, big-scale dipping paint drying furnace, sixty tons check system, large vertical auto, milling device, grinding device, Every sort of dynamic balancing equipment, double-suggestions take a look at and detection technique with 6MW (12MW) motor and other motor generation skilled equipment much more than five hundred sets, sound mechanical gear processing ability, to lay a excellent basis for buyers to increase very good quality motor merchandise.

one. The outer packaging of the items are all CZPT export-oriented wood plywood packaging.
2, the solution packaging is safeguarded by dampness, water plastic soft packaging
three. For products with particular transportation requirements (these kinds of as temperature, fragile, variability, and straightforward to get wet), the packaging security steps will be strengthened, and the goal mark will be printed on the bundle.
four. There are obvious indications and symbols on the packing box that have to be paid consideration to during transportation and storage (this kind of as position, moisture, rain, shockproof, lifting position, etc.).
