Product Description
Y, YKS, YQF, YKK, YR, YRKS, YRQF and YRKK series high voltage three-phase induction motors are new products introduced and developed by our company back in the 1980s, with more than 30 years of development history. In recent years, with improved insulation material performance, adoption of low-loss silicon steel sheets, upgraded performance levels and optimized design, the motors feature reduced various losses and increased power capacity. Drawing on our 60 years of experience in high voltage three-phase induction motor design and manufacturing, we have carried out the latest round of optimization and redesign to satisfy domestic national and industrial market demands. Test results verify that this new product series reaches or approaches the world’s 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, Africa, Hong Kong, Macao, as well as widely supplied across mainland China, winning favorable feedback from end users.
Adopting premium raw materials and mature manufacturing processes, this series motor delivers high efficiency, energy saving, low vibration, stable operation and easy installation & maintenance.
Its power grades, electrical performance, 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, this motor series provides 5 enclosure protection grades: 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 request.
Per GB/T1993 and IEC 60034-6, three standard cooling modes are optional: IC01, IC611 and IC81W. Other cooling configurations can be customized as required.
The standard structure and mounting arrangement is IMB3 (horizontal foot-mounted), conforming to GB997 and IEC 60034-7 for motor structure and mounting type codes.
Based on rotor type, protection class and cooling method, the series is divided into 8 sub-models:
| Model | Protection class | Cooling method | Squirrel cage rotor | Wound rotor |
|---|
| Damp proof | IP23 | IC01 | Y series motor | YR series motor |
| Weather-proof | IPW24 | IC01 | YQF series motor | YRQF series motor |
| Air-water cooled enclosed | IP44, IP54, IP55, IP56 | IC81W | YKS series motor | YRKS series motor |
| Air-air cooled enclosed | IP44, IP54, IP55, IP56 | IC611 | YKK series motor | YRKK series motor |
The technical data and external installation dimensions of all 10kV motors listed in this catalogue can be adapted for 3kV, 10.5kV and 11kV specifications of the same frame size.
Application
This series of high voltage motors is designed to drive general machinery such as compressors, fans, water pumps, material handling equipment, conveyors and other mechanical units. They serve as prime movers for mines, machinery plants, petrochemical facilities, power plants and other industrial & mining enterprises.
If ordered for equipment 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. This is the basis for customized design to guarantee reliable motor operation.

- For YKS and YRKS air-water cooled motors: cooling water inlet temperature 5~33ºC
- Average maximum relative humidity in the wettest month ≤90%, with average minimum temperature of that month ≤25ºC
- Power supply frequency: 50Hz±1%
- Operating voltage deviation: within ±5% of rated voltage
- Duty: continuous running duty S1
Construction Description
Y and YR are the base series with IP23 protection and IC01 cooling. Derivative versions cover other protection and cooling types including YKS (air-water cooled), YQF (weather-proof), YKK (air-air cooled), YRKS, YRQF and YRKK.
The motor adopts internationally popular box-type construction. The frame and end shields are fabricated by welded steel plates with 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 outer pressing structure. Stator windings use F-class insulation and corona-resistant materials. Winding terminals are fixed by special reliable binding techniques. The entire stator undergoes VPI vacuum pressure impregnation with F-class solventless varnish, delivering outstanding insulation, moisture resistance and shock resistance.
Most squirrel-cage rotors in this series are cast aluminum rotors with low risk of rotor bar breakage and stable running. Copper-bar squirrel-cage rotors adopt advanced, reliable welding and slot fixing technology. Wound rotors use F-class insulation and also go through VPI impregnation treatment.
Two bearing types are available: rolling bearing and sliding bearing, selected according to motor power and speed. The base protection grade for bearings is IP44; bearing protection will be upgraded accordingly for higher motor enclosure protection grades.
Motors fitted with rolling bearings are equipped with on-line oil filling and draining assemblies, allowing lubricant replenishment and discharge without machine shutdown using special tools.
The main terminal box is sealed with IP54 protection. It is normally mounted on the right side (viewed from the drive end), and can be arranged on the left side per customer request. Cable entry ports can be oriented upward, downward, left or right. Separate earthing terminals are provided inside the box.
Starting Instruction for Y, YKS, YQF, YKK Induction Motors
Advanced computer simulation calculates temperature and stress distribution for squirrel cage rotors to prevent premature motor damage caused by overload during startup. Customers shall comply with the following requirements:
- The moment of inertia of driven rotating parts (converted to motor speed) shall not exceed the allowable load J values specified in the technical data sheet
- Terminal voltage at motor terminals during startup shall not be lower than 85% of rated voltage
- Load torque characteristic matches typical pump or fan torque curve
Under above conditions, the motor permits two successive cold starts or one hot start, with natural coast-down between starts. Any further restart shall be carried out after a one-hour waiting period.
If the inertia of driven equipment exceeds the listed load J value, frequent starting is required, or heavy-load startup is needed, please contact our engineering team for customized design confirmation to ensure safe and reliable starting performance.
