Product Attributes

Product Description

Y, YKS, YQF, YKK, YR, YRKS, YRQF and YRKK series high voltage three-phase induction motors were introduced and independently developed by our company back in the 1980s, with over 30 years of development history. In recent years, upgraded insulation materials, low-loss silicon steel sheets, higher protection grades and iterative design optimization effectively cut various internal losses and boost motor capacity. Drawing on 60 years of experience in high voltage three-phase induction motor design and manufacturing, we have completed the latest round of optimization to meet domestic and industrial market demands. Test results confirm that this new series reaches or approaches the world’s advanced level in both technical and economic performance. Mass production has been realized, and products are supplied across China as well as exported to more than 20 countries and regions covering Europe, America, Africa, Hong Kong, Macao and other areas, earning consistent positive feedback from end users.

Manufactured with premium raw materials and mature production processes, this motor series features high efficiency, energy saving, low vibration, stable operation and easy installation and maintenance.

Its power grades, electrical characteristics, mounting dimensions and tolerances conform to GB755 Rotating Electric Motor Rating and Performance, IEC 60034-1 Rotating Electric Motor Rating and Performance and relevant machinery industry standards.

Five enclosure protection grades are available: IP23, IP44, IP54, IP55 and IP56, complying with GB4942.1 and IEC 60034-5 Enclosure Protection Class of Rotating Electrical Machines. IP23 version can be converted to IP44 (pipe ventilation type) or IPW24 (weather-proof type). Custom protection classes can be supplied upon customer request.

Three cooling options are offered per GB/T1993 and IEC 60034-6 Cooling Methods of Rotating Electrical Machines: IC01, IC611 and IC81W. Other cooling schemes are negotiable for special orders.

The standard structure and mounting arrangement is IMB3 (horizontal foot-mounted), following GB997 and IEC 60034-7 Motor Structure and Mounting Type Code.

Based on rotor type, protection class and cooling method, the series is divided into eight sub-models as shown below:

All technical data and external installation dimensions of the listed 10kV motors in all frame sizes can be adapted for 3kV, 10.5kV and 11kV variants.

Application

This motor series is widely used to drive compressors, fans, water pumps, scrapers, conveyors and other general machinery. It serves as the prime mover for mines, machinery plants, petrochemical facilities, power stations and other industrial and mining enterprises. For loads with large rotary inertia such as blowers, coal mills, rolling mills, crushers and belt conveyors, customers need to submit relevant technical data and sign a technical agreement with us to support customized design and guarantee reliable motor operation.

Normal operating conditions:

• Altitude no more than 1000m above sea level
• Maximum ambient temperature ≤40ºC; minimum ambient temperature: -15ºC for motors with rolling bearings, 5ºC for motors with sliding bearings; minimum ambient temperature for YKS and YRKS series is 5ºC
• For YKS and YRKS series, cooling water inlet temperature ranges from 5ºC to 33ºC maximum
• In humid months, average maximum relative humidity ≤90% while average minimum temperature ≤25ºC
• Power frequency: 50Hz±1%
• Operating voltage deviation within ±5% of rated voltage
• Duty: continuous running S1

Construction Description

Y and YR are the base models with IP23 protection and IC01 cooling. Derivative models including YKS (air-water cooled), YQF (weather-proof), YKK (air-air cooled), YRKS, YRQF and YRKK are developed from this base platform with different protection and cooling configurations.

The motor adopts the globally popular box-type construction. Frame and end shields are fabricated by welded steel plates, featuring high rigidity and low weight. After removing the protective cover or cooler, internal components are accessible for convenient installation and maintenance. The stator adopts external clamping structure. Stator windings use Class F insulation and anti-corona materials, with secure special binding for winding terminals. The whole stator undergoes VPI vacuum pressure impregnation with Class F solventless varnish, delivering outstanding insulation, moisture resistance and impulse withstand performance.

Most squirrel-cage rotors in this series are cast aluminum type with proven zero rotor breakage risk for stable operation. Squirrel-cage copper bar rotors adopt advanced reliable welding technology and firm slot fixation. Wound rotors are equipped with Class F insulation and processed via VPI vacuum pressure 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.

Motors fitted with rolling bearings are equipped with on-line grease filling and draining ports, enabling grease replenishment and discharge without shutdown using dedicated tools.

The main terminal box is sealed at IP54 grade. It is normally mounted on the right side viewed from the shaft extension end and can be relocated to the left side on request. Cable entry ports can be oriented upward, downward, leftward or rightward. An independent grounding terminal is integrated inside the box.

Starting of Induction Motor (Y, YKS, YQF, YKK)

Advanced computer simulation calculates temperature and stress distribution of 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 the driven equipment (converted to motor speed) shall not exceed the allowable load J values listed in technical datasheets
• Terminal voltage at motor terminals shall remain no lower than 85% of rated voltage during startup
• Load torque characteristic matches typical fan and pump torque curve

Under above conditions, the motor allows two consecutive cold starts or one hot start, with natural coast-down between attempts. Further restarting is permitted only after a one-hour cooling interval.

If the load inertia exceeds the listed J value, frequent startup is required, or heavy-load startup is needed, please contact our engineering team for custom design confirmation to secure reliable starting performance.
