Power Range: The YKK Series covers a rated power range from 250 kW to 4,000 kW. Its flexible power configuration caters to diverse drive requirements, from mid-sized equipment to large industrial installations, making it suitable for various large-scale machinery in industries such as power generation, metallurgy, mining, cement, and chemical processing.
Rated Voltage: Compatible with two industrial voltage levels: 6 kV and 10 kV. This aligns with mainstream high-voltage grid standards domestically and internationally, facilitating equipment matching and system integration while reducing retrofit costs. It is particularly well-suited for high-voltage applications such as large fans, pumps, and compressors.
Efficiency Class: Meets the GB30254 Grade 3 energy efficiency standard (IE3 class). Utilizing an optimized electromagnetic design and low-loss materials, it maintains high efficiency across a wide operating range, achieving 5%–10% energy savings compared to traditional high-voltage motors and significantly reducing long-term operating energy consumption.
Power Factor: Delivers a power factor of 0.85–0.90. This near-unity power factor significantly reduces reactive power losses, alleviates grid burden, improves power supply quality, and minimizes line losses. It is especially advantageous for applications with long-distance power supply, such as in mining and metallurgy.
Protection Level: Designed with IP54/IP55 protection ratings. Its totally enclosed structure effectively resists dust and water ingress, ensuring long-term, reliable operation in harsh industrial environments characterized by moisture and dust, thereby meeting the demanding requirements of such conditions.
Frame Construction: The frame is fabricated from welded high-strength steel plates, forming a robust and integral box-type structure. It provides excellent resistance to deformation and vibration, capable of reliably supporting the motor’s core components and meeting the demands of long-term, heavy-duty operation.
Cooling Method: Equipped with an IC611 cooling system featuring a built-in, independent air-to-air heat exchanger. This enables efficient closed-circuit cooling, significantly enhancing heat dissipation while effectively blocking dust and moisture ingress, making it suitable for dusty and humid harsh environments.
Insulation Class: Utilizes a Class F insulation system, designed and rated for Class B temperature rise. This provides ample thermal margin, allowing the motor to adapt to prolonged high-temperature operation and effectively extending its insulation life.
Mounting: The standard mounting configuration is IM B3 horizontal foot mounting. Its stable structural design and standardized mounting interfaces facilitate quick on-site positioning and securing, meeting the integration needs of most large-scale fixed equipment.
Bearing Type: Offers both sleeve bearing and rolling element bearing options, allowing flexible selection based on load characteristics and speed requirements. Both types employ long-life lubrication and reliable sealing to ensure stable operation.
Starting Torque: Starting torque is 0.6–0.8 times the rated torque, providing a smooth and gradual start. This effectively minimizes the impact on the power grid and the connected drive system, making it ideal for applications like fans and pumps requiring gentle startup.
Breakdown Torque: Breakdown torque reaches 1.8–2.0 times the rated torque, offering excellent short-term overload capability. This allows the motor to handle sudden load changes and instantaneous impacts, ensuring continuous and stable operation of the driven equipment under complex working conditions.
Noise Level: Operating noise is controlled to ≤88 dB(A). Through optimized electromagnetic design and mechanical construction, aerodynamic and electromagnetic noise are significantly reduced, meeting industrial requirements for quieter operational environments.
Vibration Grade: Vibration performance strictly complies with the GB 10068.3 standard. The rotor undergoes high-precision dynamic balancing correction, ensuring smooth operation across the entire speed range. This effectively extends the service life of both the motor and the equipment it drives.
Duty Cycle: Designed for S1 continuous duty operation, the motor can run uninterrupted under rated load for extended periods. Combined with its efficient cooling system, the motor’s temperature rise is consistently maintained within safe and reasonable limits.
Operating Temperature: Designed for stable operation within an ambient temperature range of -15°C to +40°C. The use of low-temperature resistant materials and a high-temperature insulation system ensures excellent electrical performance and mechanical reliability under both extreme cold and heat.
Altitude: Suitable for use at altitudes up to 1,000 meters. Applications at higher altitudes require derating according to relevant standards. Special design considerations ensure maintained insulation strength and effective cooling performance, meeting operational requirements for plateau regions.
Safety Certifications: The product has passed CCC (China Compulsory Certification) and CE (EU Conformity) marking, confirming compliance with applicable domestic and international safety standards for reliable use in various industrial settings and for export purposes.
Warranty: Backed by an 18-month warranty. Comprehensive technical support and free repair services are provided during this period, ensuring customer satisfaction and demonstrating our commitment to product quality and reliability.
Standards Compliance: The product strictly adheres to GB/T 13957 (technical requirements for high-voltage three-phase asynchronous motors), GB 30254 (energy efficiency limits and grades for high-voltage three-phase cage induction motors), and the IEC 60034 series of international standards for rotating electrical machines. Its technical specifications meet or exceed the requirements of relevant domestic and international standards.
