Available in 2, 4, 6, and 8-pole configurations, these motors cater to diverse operational speed and load characteristic requirements, ensuring broad application versatility.
Rated Voltage: With a rated voltage of 380V/400V/415V at 50Hz frequency, these motors comply with standard domestic grid specifications. They are ready for direct connection to three-phase AC power without the need for additional configuration. Their strong voltage adaptability ensures stable performance under various grid conditions.
Efficiency Class: Meeting the Grade 1 efficiency requirements of the GB18613-2020 standard (aligned with IE5 Super-Premium Efficiency international class), these motors achieve an efficiency improvement of 3 to 5 percentage points over standard models, delivering significant energy savings. The use of premium cold-rolled silicon steel sheets and high-purity copper windings reduces no-load losses by up to 30%, ensuring excellent operational economy.
Power Factor: Featuring an optimized electromagnetic design, these motors offer a high power factor, reaching above 0.88 at full load and up to 0.92 maximum. This effectively minimizes reactive power losses, improves grid power quality, reduces line losses, and enhances overall system operating efficiency.
Protection Level: Rated IP55, the motors are effectively protected against dust ingress and water jets from any direction. This makes them suitable for operation in harsh environments and contributes to an extended service life. The Totally Enclosed Fan-Cooled (TEFC) construction provides superior heat dissipation for reliable long-term performance.
Frame Construction: The high-strength cast iron frame ensures robust durability and excellent heat dissipation, capable of withstanding significant mechanical stress for stable, long-term operation. With a corrosion-resistant surface treatment, it features a clean finish and extended service life. The standard IP55 protection rating (IP65 optional) allows reliable performance in demanding environments.
Cooling Method: Designed with a Totally Enclosed Fan-Cooled (TEFC, IC411) structure, the motor incorporates an internal cooling fan. Heat is efficiently dissipated through the frame ribs. The optimized airflow design enhances cooling performance, resulting in low temperature rise and ample thermal margin, even under high ambient temperature conditions.
Insulation Class: The Class F insulation system provides a generous temperature rise margin and long insulation life, supporting reliable operation at elevated temperatures. The stator is processed using vacuum pressure impregnation (VPI), ensuring stable insulation performance, high resistance to voltage surges, and safe long-term operation.
Mounting Configurations: Multiple mounting options are available, including B3, B5, and B35 arrangements, to accommodate horizontal, vertical, and other installation requirements. The frame feet are sensibly designed with standardized fixing holes for quick and secure connection to driven equipment, reducing installation time.
Bearing System: Equipped with high-quality deep groove ball bearings or cylindrical roller bearings for strong load capacity and smooth operation. Designed for extended service intervals, the bearing system features long-life lubrication and a standard dust-sealed structure. Maintenance intervals of up to 20,000 operating hours help minimize maintenance costs.
Starting Torque: Featuring a high starting torque ratio of 220%-250% of rated torque, these motors deliver excellent starting performance, making them suitable for heavy-duty and frequent start-stop applications. They ensure smooth, low-impact starting, minimizing stress on both the electrical supply and driven equipment for enhanced adaptability.
Breakdown Torque: With a high breakdown torque ratio of 250%-280% of rated torque, the motors offer strong overload capacity. They can withstand short-term overload conditions and perform reliably in complex operational scenarios, maintaining stable operation even under temporary overloading.
Noise Level: Designed with a low-noise fan and optimized cooling airflow, the motors operate quietly in compliance with GB10069 standards. The typical sound pressure level at 1 meter distance is ≤75 dB(A), contributing to a better working environment. This makes them ideal for noise-sensitive locations such as office buildings and hospitals.
Vibration Grade: The rotor is dynamically balanced to achieve an “R” grade (Excellent) vibration severity standard. This results in exceptionally smooth operation, reducing transmitted vibration and mechanical stress on connected equipment. The vibration velocity is typically ≤2.3 mm/s, supporting long-term operational stability.
Duty Cycle: Rated for S1 continuous duty operation, the motors are engineered for reliable long-term running with stabilized temperature rise. Their optimized thermal management design lowers temperature rise by approximately 15K compared to conventional motors, ensuring effective heat dissipation across various industrial drive applications.
Operating Temperature Range: Designed for reliable operation in ambient temperatures from -15°C to +40°C. With a generous thermal margin, it remains stable across various climate conditions. An optimized cooling design ensures consistent performance even in high-temperature environments.
Altitude: Suitable for direct use at altitudes up to 1,000 meters. For installations above this level, derating is recommended. Customized solutions, including anti-corrosion, moisture-resistant, and explosion-proof treatments, are available for specialized applications.
Safety & Efficiency Certifications: The motor is certified to CCC (China Compulsory Certification) and CE standards, ensuring compliance with national electrical safety regulations for reliable and safe operation. Its energy-saving performance is officially recognized through the China Energy Label certification.
Warranty & Support: The complete motor is backed by an 18-month warranty, with bearings covered for 12 months. We provide comprehensive technical support and after-sales service to safeguard your investment, including free repair services during the warranty period.
Compliance Standards: Conforms to Chinese National Standards GB18613-2020, GB/T 755, and GB/T 10069, with performance meeting advanced international levels. The motor also complies with the IEC 60034 international standard series, fulfilling requirements for global exports.
