Green and Intelligent Drive High-Quality Development: Hanwha Denso Awarded the Provincial “Green Factory” Title

Release Time:

2025-12-19

  With years of deep engagement in the industry, Jinzhou Hanwha Electric Components Co., Ltd. has consistently integrated the concept of green development into every aspect of its production and operations. Driven by a dual approach—“green foundations and intelligent empowerment”—the company has forged a development path that equally emphasizes ecological and economic benefits. Recently, it was successfully awarded the provincial-level “Green Factory” title.

  Stepping into the company’s armature production workshop for starter motors, you’ll find intelligent manufacturing scenarios everywhere: robotic arms precisely carry out the entire process—from material handling and transportation to assembly. The high-speed operation of the automated production lines not only significantly boosts productivity but also lays a solid foundation for the company’s green transformation. Over the years, the company has established a comprehensive, finely tuned green management system covering everything from energy consumption control and pollutant emission management to optimization of production processes and resource recycling. 
  “We’ve built a carbon management platform that enables precise control over production data. By leveraging AI technology, we’ve not only reduced production costs but also improved product quality and boosted production efficiency,” said a technical specialist from the company. Among the flexible, intelligent production lines introduced by the company, 47 technologies have met the requirements of the relevant recommended catalog. Since the beginning of this year, the company has been advancing an average of 7.33 green and low-carbon projects annually, while strictly adhering to the principle of intensive land use and continuously enhancing its level of green development.

  As a high-tech enterprise, Jinzhou Hanwha Electric Components has consistently adhered to innovation-driven development. From being recognized early on as a “Star Enterprise” and an “Excellent Enterprise,” to recently earning provincial titles such as “Specialized, Refined, Unique, and Innovative Enterprise” and “Industrial Design Center Enterprise,” the company has upheld the philosophy of “Pursuing Excellence.” It regards green transformation as an extension of its development strategy—“prioritizing quality and enhancing efficiency.” The designation of “Green Factory” has provided yet another boost to the company’s growth. 
  Being awarded the title of “Provincial Green Factory” not only demonstrates the company’s strong capabilities in the green and low-carbon sector but also helps enhance its market competitiveness and secure more green orders. Taking this opportunity as a stepping stone, the company has now initiated the application process for the national-level Green Factory designation. Going forward, it will comprehensively deepen its efforts in resource conservation, green production, and green supply-chain management, firmly implement its low-carbon development strategy, set a new benchmark for green and intelligent manufacturing in the industry, and strive to become a nationally influential specialist manufacturer of intelligent, high-quality motor components.

Methods for winding the armature of a DC brushless automotive motor

The method for winding the armature winding of a DC brushless car motor is to leave a section of the cable end free and tie it tightly to the shaft. Hold the car armature with one hand, and wind the coil inductance clockwise with the other hand. Taking a five-slot armature as an example, the first coil is 1-5, the second coil is 2-6, then 3-7..., and so on. The sides of many components are on the next layer. The 5-9 components have one side on the next layer and the other side on the top layer. The sides of many components are on the top layer. In order to ensure the insulation between the top layer and the next layer components, it is advisable to place 0.1-0.15mm thick insulating paper pads in between. When the coil inductance in the slot reaches a certain level, a crossbar is needed to make it reach the bottom of the slot. When winding the coil inductance, the wire should be tightened first. Whether in the slot or the wire connection part, it is necessary to prevent the occurrence of crossed turns to prevent excessive space occupation and short circuit between turns due to partial stress of the wire. After all the windings are wound, the wire ends of the same winding component are bundled together, then the insulation layer of the wire connector is removed, different color waterproof sleeves are used, and they are embedded in the corresponding commutator segments. The important role of the armature in a DC brushless motor: DC motor,

Design rules for automotive armatures

Automotive armature manufacturers indicate that single-layer windings are not suitable for large-capacity motors, and small-capacity motors should not be double-layered. The magnetic flux density of the motor core should not be too high or too low. When the frequency and thickness of the silicon steel sheet core material are constant, the iron loss depends on the magnetic flux density. If the magnetic flux density is too high, the iron loss increases, and the motor efficiency decreases. The increased heat from the iron core increases the motor temperature, and the increased excitation power increases the motor power factor, so the magnetic flux density of the core should not be too high. Try to avoid excessive saturation of the magnetization curve. If the magnetic density is too low, it will increase the amount of motor material used, increasing the cost. The rotor teeth are narrow, the magnetic density is high, the slot entry wire is large, that is, the automotive armature slots are large. Automotive armature manufacturers indicate that due to poor air conduction, there are many gaps in the slots, affecting the coils and easily damaging the heat dissipation of the insulation material, accelerating the increase in motor temperature. The slot fill factor of the motor slots cannot be too high or too low. Usually, the slot fill factor for low-speed motors is 75% to 85%, which can effectively prevent the enamelled wire from loosening in the slots. The design of the motor rotor slot shape should use parallel trapezoidal recesses as much as possible, and the edges of the recesses should not have sharp corners. Try to use a circular bottom recess, because the circular slot is filled with aluminum, which is easy to injection mold and the stator chip is easy to insert. The coil current density should not be...
