- Product Description
3.3kV Motor for Industrial Applications — Medium-Voltage, Wide Power Range, Flexible Configuration
Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. sources and supplies 3.3kV motor units for demanding industrial environments. The series covers a power range of 160–1600 kW with voltage options spanning 3000V to 11000V (±5%), making it applicable to fans, pumps, compressors, and heavy machinery. Units are sourced from a network of over 30 verified manufacturers and comply with JB/T10444-2004 standards. Certifications available include CCC, CE, ISO9001, and CQC, depending on the manufacturer and model selected.
3.3kV Motor Manufacturer and Supplier
Sourcing a medium-voltage motor above 3kV often involves navigating inconsistent quality across suppliers, limited model availability, and uncertain delivery timelines — particularly for non-standard voltage requirements.
Qihe Xicheng maintains direct working relationships with over 30 motor manufacturers, including ABB, Siemens, Wolong, NEC, SIMO, PINXING, XEMC, and CHANGSHA. This network covers a broad range of power ratings, frame sizes, and voltage configurations within a single sourcing channel.
Order tracking, production scheduling, and quality control are managed through an SAP factory management system, providing documented visibility across each production stage.
Common Sourcing Challenges and How They Are Addressed
Challenge | What We Offer |
Voltage mismatch for site conditions | Six standard voltage levels: 3000V, 3300V, 6000V, 6600V, 10000V, 11000V (±5%) |
Space constraints at installation site | Compact frame design with reduced installation footprint |
Noise sensitivity in plant environments | Low-noise construction with precision-balanced rotors |
Bearing brand requirements | SKF, NSK, or FAG bearings available on request |
Non-standard delivery schedules | Production cycles coordinated based on project timelines |
After-sales response coverage | Support available seven days a week, including weekends |
Technical Characteristics
The 3.3kV motor series uses a compact frame that lowers the installation footprint without reducing output stability. The power range of 160 to 1600 kW allows selection of the capacity most appropriate for the connected equipment.
Rotor components undergo dynamic balancing before assembly, keeping vibration levels low during operation. Reduced vibration limits mechanical wear on both the motor and connected machinery, which is relevant in continuous-operation settings such as water treatment or mining.
The motor design allows access to key components during routine servicing. Bearings — selectable from SKF, NSK, or FAG — can be specified to align with existing maintenance standards or load profiles.

Production and Quality Process
Each motor order is managed through the SAP factory system, covering production scheduling, component tracking, and documentation at each stage.
Stator windings use insulation materials rated for medium-voltage operation above 3kV. Rotor assemblies are dynamically balanced prior to installation to confirm vibration performance under load.
Final units are tested against rated voltage, current, and torque specifications before shipment. Units that do not pass electrical and mechanical verification are not released.
Industry Applications
The 3kV to 11kV motor range serves industries that require sustained high-power output across extended operating cycles. This series is suited for the following equipment types:
· Fans — industrial ventilation in power plants and manufacturing facilities
· Water pumps — municipal water supply, irrigation, and industrial fluid transfer
· Compressors — oil and gas processing, refrigeration, and pneumatic systems
· Crushers — mining, quarrying, and aggregate processing
· Cutting machine tools — metal fabrication and heavy machining
· Transportation machinery — conveyor systems, hoists, and port equipment
The motor's low-vibration output and stable power delivery reduce mechanical stress on driven equipment across these use cases.
Configuration Options
Standard catalog specifications do not always match project requirements. The engineering team can adjust product dimensions to suit specific installation constraints or mechanical interface needs.
Bearing selection — SKF, NSK, or FAG — can be specified based on load demands or maintenance preferences. Voltage configuration covers six standard levels from 3000V to 11000V with ±5% tolerance, allowing the motor to integrate with existing electrical infrastructure.
Logistics arrangements cover sea freight, land transport, air freight, and multimodal options, coordinated based on delivery location and project schedule.

FAQ
Q: What does 3.3kV indicate for motor?
A: 3.3kV means the rated supply voltage - 3,300 volts. It is a medium voltage class used in industrial applications where high power is required but at a lower current than low voltage systems, making power distribution over long distances easier.
Q: Is 3.3kV a high voltage?
A: Most industrial standards consider 3.3kV as a medium voltage. High voltage often starts at 11kV and above. The 3kV–6.6kV range is typical for heavy industrial and infrastructural applications.
Q: What is the power range of this series?
A: The series is from 160 kW to 1600 kW, ideal for mid-size industrial equipment and large-capacity machines like compressors and crushers.
Q: Can I request a specific bearing brand?
A: Yes. SKF, NSK and FAG bearings may be specified due to load requirements, maintenance schedules or procurement norms. Please state your preference while enquiring.
Q: What voltages do you offer?
A: The standard voltage levels are 3000V, 3300V, 6000V, 6600V, 10000V and 11000V with tolerance of ±5%. Custom configurations might be considered according to site specifications.
Q: What kind of certificates can be earned?
A: Certifications we have are CCC,CE,ISO9001,CQC,CRCC,UL,GOST,energy saving certification. Exact paperwork is different for every manufacturer and model. Contact Us to check if your target market is available.
