Y, YKS, YQF, YKK, YR, YRKS, YRQF and YRKK series high voltage three-phase induction motors were developed and launched by our company in the 1980s, with more than 30 years of development history. In recent years, with the upgraded performance of insulating materials, the adoption of low-loss silicon steel sheets, and continuous design optimization, motor losses have been effectively reduced and motor capacity improved. Combining our 60 years of experience in high voltage three-phase induction motor design and manufacturing, we have completed the latest round of optimization design to meet domestic and industrial market requirements. Test results show that the new series reaches or approaches the global advanced level in both technical and economic performance. These motors are mass-produced and exported to more than 20 countries and regions including Europe, America and Africa, as well as widely supplied across China, winning consistent recognition from end users.
This series adopts premium raw materials and mature manufacturing processes, featuring high efficiency, energy saving, low vibration, stable operation and convenient installation and maintenance.
Its power grades, electrical characteristics, mounting dimensions and tolerances comply with GB755 Rotating Electrical Machines - Ratings and Performance, IEC 60034-1 Rotating Electrical Machines - Ratings and Performance and relevant machinery industry standards.
In accordance with GB4942.1 and IEC 60034-5, there are 5 enclosure protection classes for this motor series: IP23, IP44, IP54, IP55 and IP56. IP23 motors can be converted to IP44 (pipe ventilation type) or IPW24 (weather-proof type). Custom protection classes are available upon customer request.
Per GB/T1993 and IEC 60034-6 (cooling methods for rotating electrical machines), three standard cooling options are available: IC01, IC611 and IC81W. Other cooling modes can be customized if required.
The standard construction and mounting arrangement is IMB3 (horizontal foot-mounted), conforming to GB997 and IEC 60034-7.
Based on rotor type, protection class and cooling method, the series is divided into 8 sub-series as shown below:
| Type | Protection Class | Cooling Method | Squirrel Cage Rotor | Wound Rotor |
|---|---|---|---|---|
| Damp Proof | IP23 | IC01 | Y Series | YR Series |
| Weather Proof | IPW24 | IC01 | YQF Series | YRQF Series |
| Water-Air Cooled Enclosed | IP44, IP54, IP55, IP56 | IC81W | YKS Series | YRKS Series |
| Air-Air Cooled Enclosed | IP44, IP54, IP55, IP56 | IC611 | YKK Series | YRKK Series |
All technical data and external installation dimensions of 10kV motors in this catalogue can be adapted for 3kV, 10.5kV and 11kV versions with the same frame sizes.
This motor series drives various equipment including compressors, fans, water pumps, chip removers, conveyors and other mechanical units. It serves as prime mover for mines, machinery plants, petrochemical facilities, power plants and other industrial and mining sites.
For loads with large rotary inertia such as blowers, coal mills, rolling mills, crushers and belt conveyors, customers shall provide relevant technical parameters and sign a technical agreement with us for customized design, to guarantee reliable motor operation.
Y and YR are base models with IP23 protection and IC01 cooling. Derivative types include YKS (water-air cooled), YQF (weather-proof), YKK (air-air cooled), YRKS, YRQF and YRKK.
The motor adopts international popular box-type construction. Frame and end shields are steel plate welded for high rigidity and light weight. After removing the protective cover or cooler, internal inspection and access are available for easy installation and maintenance.
The stator uses external pressing structure. Stator windings adopt Class F insulation and anti-corona materials. Winding terminals are fixed by special reliable binding technology. The whole stator goes through VPI vacuum pressure impregnation with solventless Class F varnish, delivering outstanding insulation, moisture resistance and shock resistance.
Squirrel cage rotors are mostly cast aluminum type with low failure rate and stable operation. Copper bar squirrel cage rotors adopt advanced reliable welding and slot fixing technology. Wound rotors use Class F insulation and VPI impregnation treatment.
Two bearing configurations are optional: rolling bearing and sliding bearing, selected according to motor power, speed and protection requirements. Base bearing protection class is IP44; bearing protection will be upgraded for higher enclosure protection grades.
Rolling bearing version is equipped with on-line grease filling and draining ports, supporting non-stop oil replenishment and discharge with special tools.
Main terminal box is sealed to IP54. It is normally fitted on the right side (viewed from shaft extension), and can be switched to left side per request. Cable entry holes can be arranged upward, downward, left or right. Independent grounding terminals are equipped inside the box.
Rotor thermal and pressure distribution are calculated via professional computer simulation to avoid premature motor damage caused by overload during startup. Customers shall comply with the following requirements:
Under above conditions, the motor allows two successive cold starts or one hot start, with natural coast-down interval between starts. Additional restart is permitted after 1 hour cooling if the startup limit is reached.
If the load inertia exceeds the listed value, frequent startup or heavy-load startup is required, please contact our engineering team for customized design confirmation.
