As a typical representative of the third generation of high-efficiency and energy-saving three-phase asynchronous motors, the design of the motor YBX3-250M-4-55KW strictly follows the standard requirements of GB18613-2020 “Energy Efficiency Limit Values ​​and Energy Efficiency Grades for Motors” and reaches IE3 energy efficiency grade certification. This model adopts a 250M medium-sized base, a 4-pole synchronous speed design, and a rated power of 55kW. On the basis of maintaining the structural advantages of the traditional Y series motors, it has achieved energy efficiency breakthroughs through electromagnetic optimization and material upgrades.

The core technology innovation is reflected in:

1. The electromagnetic system uses high-conductivity cold-rolled silicon steel sheets for lamination, and the slot matching is optimized to make the magnetic circuit distribution more uniform

2. The rotor uses copper guide bars instead of traditional aluminum materials, and the conductivity is increased by more than 30%

3. The temperature resistance level of the new insulation system reaches F level (155℃), which effectively reduces the temperature rise

4. The cooling air duct design optimized by fluid dynamics improves the heat dissipation efficiency by 18%

Motor YBX3-250M-4-55KW has outstanding value in industrial production due to its high torque density and wide voltage adaptability (380V±10%):

- Fluid machinery field: As the driving core of centrifugal water pumps (flow rate 800m³/h) and Roots blowers, it achieves an overall energy efficiency improvement of 5-7% in municipal water supply systems

- Material handling system: When driving a belt conveyor (bandwidth 1200mm), the annual power saving can reach 21,000 kWh compared with the previous generation of products

- Compressor unit matching: In the application of screw air compressor (exhaust volume 40m³/min), the impact current is reduced by 40% through soft start adaptation

- Special equipment integration: When adapting to the ball mill (volume 15m³) in the cement industry, the frequency conversion control solution is used to achieve a 1.8kW·h reduction in power consumption per ton

Key points to pay attention to in engineering design:

1. Load characteristic matching: It is recommended to leave a 15% power margin for fan-type square torque load

2. Installation environment requirements: Altitude not exceeding 1000m, ambient temperature -15℃~40℃

3. Transmission system optimization: It is recommended to use TSD type elastic coupling for direct drive

4. Maintenance cycle planning: Add grease every 4000 hours of operation (amount 120g)

The motor YBX3-250M-4-55KW has shown significant energy-saving benefits in technical transformation projects in petrochemical, metallurgical, building materials and other industries through structural innovation and material upgrades. With the advancement of the carbon peak policy, this model will serve as the core equipment for upgrading industrial power systems and continue to promote the green transformation of the manufacturing industry. Its full life cycle cost advantages and technical scalability provide reliable equipment support for industrial enterprises to achieve the “dual carbon” goals.
