The 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 iteration history. Thanks to continuous upgrades in insulation materials, adoption of low-loss silicon steel sheets, grade promotion and design optimization, all types of motor losses are reduced while power capacity is improved. Combining our 60 years of experience in high voltage three-phase induction motor design and manufacturing, we have carried out the latest round of optimization to meet domestic and industrial market demands. Test results show that this new series reaches or approaches the world advanced level in both technical and economic indicators. Mass production has been realized, and products are sold widely across China and exported to over 20 countries and regions including Europe, America, Africa, Hong Kong and Macao, winning consistent positive feedback from end users.
Manufactured with premium raw materials and mature production processes, this series features high efficiency, energy saving, low vibration, stable operation and convenient installation and maintenance.
Its power ratings, electrical performance, mounting dimensions and tolerances conform to GB755 Rotating Electrical Machines – Ratings and Performance, IEC 60034-1 Rotating Electrical Machines – Ratings and Performance, as well as relevant machinery industry standards.
In accordance with GB4942.1 and IEC 60034-5, there are five enclosure protection grades: IP23, IP44, IP54, IP55 and IP56. IP23 motors can be converted to IP44 (pipe ventilation type) or IPW24 (weather-protected type). Custom protection grades are available upon request.
Three standard cooling methods are offered per GB/T1993 and IEC 60034-6: IC01, IC611 and IC81W. Other cooling modes can be customized as required.
The standard construction and mounting form is IMB3 (horizontal foot-mounted), complying with GB997 and IEC 60034-7 Rotating Electrical Machines – Constructional Types and Mounting Arrangements.
Based on rotor type, protection class and cooling method, the series is divided into 8 sub-models as shown below:
| Model Series | 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 Type | IP44, IP54, IP55, IP56 | IC81W | YKS Series | YRKS Series |
| Air-air Cooled Closed Type | IP44, IP54, IP55, IP56 | IC611 | YKK Series | YRKK Series |
The technical data and overall installation dimensions of 10kV motors listed in this catalogue can be adapted for 3kV, 10.5kV and 11kV specifications of the same frame size.
This series is designed to drive general machinery such as compressors, ventilators, water pumps, unloaders and conveying equipment, serving as prime movers for mines, machinery plants, petrochemical facilities, power plants and other industrial and mining enterprises.
For motors driving equipment with large rotary inertia including blowers, coal mills, rolling mills, crushers and belt conveyors, customers need to provide relevant technical parameters and sign a technical agreement with us for targeted design, to guarantee reliable motor operation.
Y and YR are the base models with IP23 protection and IC01 cooling. Derivative models including YKS (air-water cooled), YQF (weather-protected), YKK (air-air cooled), YRKS, YRQF and YRKK are developed from the base design.
These motors adopt internationally popular box-type construction. The frame and end shields are steel plate welded, featuring high rigidity and light weight. After removing the protective cover or cooler, internal inspection and access are possible for easy installation and maintenance. The stator adopts external press-fit structure. Stator windings use F-class insulation and anti-corona materials. Winding terminals are fixed with special reliable binding techniques, and the whole stator undergoes VPI vacuum pressure impregnation with F-class solventless varnish, delivering stable insulation, moisture resistance and impulse resistance.
Most squirrel-cage rotors are cast aluminum type with low failure rate for dependable operation. Copper bar squirrel-cage rotors adopt advanced reliable welding and slot fixing processes. Wound rotors are equipped with F-class insulation and also processed by VPI impregnation.
Two bearing types are available: rolling bearing and sliding bearing, selected according to motor power and speed. The base bearing protection grade is IP44 and will be upgraded together with higher motor enclosure protection.
Rolling bearing versions are fitted with on-line oil filling and draining devices, allowing lubricant replenishment and discharge without stopping the motor.
The main terminal box is sealed at IP54 grade. It is normally mounted on the right side (viewed from shaft extension), and can be rearranged to the left side per customer request. Cable entry holes can be oriented upward, downward, left or right, and an independent grounding terminal is provided inside the box.
Finite element thermal and stress simulation is performed on squirrel cage rotors to avoid premature damage caused by overload during startup. Customers shall comply with the following requirements:
When the above conditions are satisfied, the motor allows two successive cold starts or one hot start, with natural coast-down between attempts. A further restart is permitted only after a 1-hour waiting period once the start limit is reached.
If the load inertia exceeds the specified value, frequent starting or heavy-load startup is required, please contact our engineering team for customized design to ensure reliable starting performance.
