Product Description
Our Y, YKS, YQF, YKK, YR, YRKS, YRQF, YRKK series high voltage three-phase induction motors were developed based on technology introduced in the 1980s, with more than 30 years of iteration and upgrading. Supported by upgraded insulation materials, low-loss silicon steel sheets, enhanced performance grades and iterative design optimization, the motors cut various energy losses and boost power density. Drawing on our 60 years of experience in high voltage induction motor design and manufacturing, we completed the latest round of optimization to meet domestic and industrial market demands. Verified by performance tests, this motor series reaches or approaches world-leading standards in both technical and economic indicators. Mass production has been realized, and products are widely supplied across China and exported to over 20 countries and regions including Europe, America and Africa, earning consistent positive feedback from end users.
Manufactured with premium raw materials and mature production processes, these motors feature high efficiency, low vibration, stable operation and easy installation and maintenance.
Power ratings, 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.
Five enclosure protection grades are available: IP23, IP44, IP54, IP55 and IP56, conforming to GB4942.1 and IEC 60034-5. IP23 motors can be converted to IP44 (pipe ventilation) or IPW24 (weather-protected type). Other protection grades can be customized upon request.
Three standard cooling methods are offered: IC01, IC611 and IC81W, following GB/T1993 and IEC 60034-6. Alternative cooling solutions are available for special requirements.
The standard construction and mounting form is IMB3 (horizontal foot-mounted), complying with GB997 and IEC 60034-7.
Based on rotor type, protection class and cooling method, the series is divided into 8 sub-models:
| Model Category | Protection Class | Cooling Method | Squirrel Cage Rotor | Wound Rotor |
|---|
| Drip-proof | IP23 | IC01 | Y Series | YR Series |
| Weather-protected | IPW24 | IC01 | YQF Series | YRQF Series |
| Air-water Cooled Closed | IP44, IP54, IP55, IP56 | IC81W | YKS Series | YRKS Series |
| Air-air Cooled Closed | IP44, IP54, IP55, IP56 | IC611 | YKK Series | YRKK Series |
All dimension data and installation drawings for 10kV motors in this range can be adapted for 3kV, 10.5kV and 11kV variants.
Application
This motor series drives general equipment such as compressors, fans, water pumps, crushers and conveyors, serving as prime movers for mines, machinery plants, petrochemical facilities, power plants and other industrial and mining sites.
For heavy-inertia loads including blowers, coal mills, rolling mills, crushers and belt conveyors, customers shall submit full technical parameters and sign a technical agreement with us before order confirmation to guarantee stable motor operation.

Construction Description
Y and YR are the base models (IP23, IC01). All derivative models including YKS (air-water cooled), YQF (weather-protected), YKK (air-air cooled), YRKS, YRQF and YRKK are developed from this base platform.
Adopting the widely accepted box-type structure, the frame and end shields are steel plate welded for high rigidity and lightweight design. After removing the protective cover or cooler, internal components are accessible for convenient inspection, installation and maintenance.
The stator adopts external core clamping structure. Stator windings use Class F insulation and anti-corona materials. Winding terminals are secured by professional binding techniques. The whole stator undergoes Class F solventless VPI vacuum pressure impregnation treatment, delivering outstanding insulation, moisture resistance and shock resistance.
Most squirrel-cage rotors use cast aluminum construction with excellent anti-fracture performance and high operational reliability. Copper-bar squirrel-cage rotors adopt advanced slot welding and fixing technology. Wound rotors are equipped with Class F insulation and also processed via VPI impregnation.
Two bearing types are optional: rolling bearing and sliding bearing, selected according to motor power, speed and protection grade. Base bearing protection grade is IP44; higher motor protection grades come with upgraded bearing protection accordingly.
Motors fitted with rolling bearings are equipped with on-line grease filling and draining ports, allowing refueling and oil discharge without shutdown.
The main terminal box is sealed to IP54 standard. It is fitted on the right side (viewed from shaft extension) and can be rearranged to the left side on request. Cable entry direction can be adjusted to top, bottom, left or right. Independent grounding terminals are integrated inside the box.
Starting Instruction for Y, YKS, YQF, YKK Induction Motors
Finite element thermal and stress simulation is applied to squirrel cage rotors to avoid premature damage caused by starting overload. Customers shall comply with the following requirements:
- The total inertia of driven equipment (converted to motor speed) shall not exceed the allowable load inertia value listed in technical datasheets
- Terminal voltage at motor terminals during starting shall remain no less than 85% of rated voltage
- Load torque characteristic matches typical fan or pump curve
Under above conditions, the motor permits two successive cold starts or one hot start, with natural coast-down between attempts. Further restarting is allowed after a 1-hour cooling period.
If load inertia exceeds specified limits, frequent starting is required or heavy-load startup is needed, please contact our engineering team for customized design to ensure reliable starting performance.
