Custom Single-Phase Asynchronous Motors Manufacturers

Why choose aluminum as the main material for the single-phase motor housing?

1. Lightweight, easy to install and transport

The density of aluminum is about one-third of that of steel. This remarkable lightweight feature greatly reduces the weight of the single-phase motor housing made of aluminum. At the installation site of the building ventilation system, if a small fan is equipped with an aluminum shell single-phase motor, the installers do not need to use heavy lifting equipment, and two people can easily complete the high-altitude positioning and fixing, which greatly improves the construction efficiency of the ventilation renovation of high-rise buildings. In the field of logistics and transportation, lightweight motors can increase the single-load capacity of freight vehicles. Taking long-distance freight as an example, the extra cargo carried by each vehicle due to the weight reduction of the motor can create considerable transportation revenue for logistics companies every year.

2. Good heat dissipation performance

The motor will generate a lot of heat during operation. If the heat cannot be dissipated in time, it will cause the internal temperature of the motor to rise, affecting the performance and service life of the motor, and may even cause safety accidents. The thermal conductivity of aluminum is about 4 times that of steel, and its internal lattice structure gives it efficient heat conduction. When the motor winding generates heat, the aluminum shell can quickly evacuate the heat to the outside air like an efficient heat transfer channel.​
Aluminum Housing Single Phase Motors produced by Hangzhou Hengbai Reducer strictly implements procedures such as raw material supplier screening and auditing, incoming material testing, and incoming material comparison in material control to ensure that the aluminum material used has excellent heat dissipation performance. At the same time, with the help of first-class production process design and program control, the surface of the motor housing is designed with precise heat dissipation ribs. These ribs not only increase the heat dissipation area, but also optimize the air flow path, further enhancing the heat dissipation effect. In the continuous operation test under high temperature environment, the temperature rise of the aluminum housing motor is significantly lower than the industry standard. This good heat dissipation performance not only ensures the stability and reliability of the motor during long-term continuous operation, but also extends the service life of the motor, reduces maintenance costs, and brings tangible economic benefits to users. ​
3. Excellent corrosion resistance​
In many industrial environments and daily life scenes, motors are inevitably affected by corrosive substances such as moisture, acid and alkali. A layer of aluminum oxide film with a thickness of only a few nanometers but extremely dense will quickly form on the surface of aluminum in the air. This film is like a solid armor that can effectively prevent the invasion of external corrosive substances and protect the aluminum matrix from corrosion. Take coastal ports as an example. The sea breeze carries high concentrations of salt. Ordinary steel shell motors will rust within half a year, while aluminum shell motors remain intact after several years. ​
4. good processing performance​
Aluminum has good processing performance and is easy to process by casting, cutting, stamping and other processing techniques. In the precision casting workshop, liquid aluminum can accurately fill the complex mold cavity to shape the heat sink fins with micron-level precision; the CNC machining center can perform high-speed milling on the aluminum shell to complete the processing of thin-walled structures. This allows motor manufacturers to process aluminum into motor shells of various shapes and sizes according to different design requirements. ​
Hengbai Reducer has professional technical personnel and advanced processing equipment, which can make full use of the processing performance advantages of aluminum to perform fine processing on the shell of aluminum shell single-phase motors. By introducing simulation technology, the shell structure is optimized in the design stage, the processing allowance is reduced, and the material utilization rate is improved. The automated stamping production line achieves efficient production of dozens of pieces per minute, which greatly reduces the production cost. These advantages make aluminum shell single-phase motors more price competitive in the market and meet the requirements of different customers for motor appearance and performance.​
5. Good electromagnetic shielding performance​
With the increasing popularity of modern electronic devices, electromagnetic interference issues are receiving more and more attention. The motor will generate electromagnetic radiation during operation, which may interfere with the surrounding electronic equipment and affect their normal operation. The free electrons in the aluminum atoms resonate under the action of electromagnetic radiation to form a reverse electromagnetic field, thereby effectively offsetting external interference. In the medical imaging equipment room, the aluminum shell motor can reduce the intensity of electromagnetic interference by more than 90%, ensuring that the imaging accuracy of the MRI is not affected. ​
Single-Phase Asynchronous Motors, by using aluminum shells, provides users with a more stable and reliable electromagnetic environment. The company's R&D team has conducted in-depth research on the electromagnetic shielding mechanism, and further improved the shielding effect by optimizing the shell joint structure, adding conductive coatings and other technical means. Whether in laboratory equipment with high requirements for the electromagnetic environment, or in the application of supporting motors for some precision electronic instruments, aluminum shell single-phase motors can meet users' requirements for electromagnetic compatibility and show their advantages in technology and performance.​
6. Environmental Protection and Sustainability​
As the world's attention to environmental protection and sustainable development continues to increase, all walks of life are actively seeking more environmentally friendly materials and production methods. Aluminum is a recyclable metal material with a relatively simple recycling process, and the recycled aluminum can be reused in production, greatly reducing the consumption of natural resources. The energy consumption of recycled aluminum production is only 5% of that of primary aluminum, and 13 tons of carbon emissions can be reduced for every ton of aluminum recycled. ​
As a member of the China Industrial Products Mechanical Transmission Industry Association, Hengbai Reducer has always adhered to the concept of green development and fully considered the environmental sustainability of aluminum materials in the production process. The company has established a complete waste motor recycling system, and through cooperation with professional recycling agencies, it ensures that the aluminum shell can be efficiently recycled. Through a strict quality management system and standardized production processes, it ensures that the aluminum shell single-phase motor can meet environmental protection requirements throughout its life cycle. At the same time, the ROHS and other certifications obtained by the company also fully prove the excellent performance of its products in environmental protection, and contribute to promoting the green development of the industry.
