It is a professional motor manufacturing enterprise integrating R&D, manufacturing and sales, and was awarded the title of Sichuan Provincial Innovative Small and Medium-sized Enterprise in 2025. The company has 20 automated motor production lines with an annual production capacity of 20 million units. Its products are widely used in kitchen small home appliances such as egg beaters, meat grinders, blenders and juicers, as well as office equipment and electric models, making it an important micro-special motor production base in Southwest China. The company has jointly built a micro-special motor research institute with universities and holds a number of core motor technology patents. The completion of the second phase project will further expand production capacity to meet the growing market demand.
Cooperative Product
PEWAL/155 Grade 1 Class 155 Thin Film Polyester Enameled Round Aluminum Wire
● Standards: GB/T 7095.4-2008, IEC 60317-0-3:2008
● Thermal Class: Class F (155°C)
● Film Type: Thin film (Type 1), modified polyester insulating varnish
● Conductor Material: High-purity electrical aluminum
● Diameter Range: φ0.15mm ~ φ3.00mm
● Core Features: High slot fill factor, compact winding, excellent cost performance
Application Scenarios
This product is mainly used in the manufacturing of stator windings for various series motors and DC brushed motors produced by Chaohang Motor, and is widely matched with mainstream kitchen small home appliance products including egg beaters, meat grinders, blenders, juicers and food processors. As the core conductive and insulating material of small home appliance motors, PEWAL/155 Grade 1 enameled aluminum wire, with its high slot fill factor advantage brought by thin film, achieves higher power output in limited motor space, perfectly adapting to the development trend of miniaturization and lightweight of small home appliance motors.
Product Advantages
● Thin film design, slot fill factor increased by 8%-12% compared with thick film products, which can significantly improve motor power density
● Excellent mechanical strength and film adhesion, suitable for high-speed automatic winding processes over 3000 rpm
● Good electrical insulation performance and solvent resistance, stable breakdown voltage and high insulation reliability
● Lightweight design, reduces motor weight by more than 30% and material cost by about 28% compared with copper enameled wire of the same specification
● Full-process online inspection ensures uniform film, no pinholes and highly stable batch quality
Cooperation Value
Since the cooperation, our company has provided stable and reliable supply of PEWAL/155 Grade 1 enameled aluminum wire products to Sichuan Chaohang Motor, fully supporting its production capacity expansion and product upgrading strategy. We have optimized the products according to the special application requirements of kitchen small home appliance motors, helping Chaohang Motor further reduce production costs while ensuring motor performance and enhance product market competitiveness. Both parties have established a long-term and stable strategic partnership.
