The size of the hairpin winding motor is reduced by about 30% compared to the round coil type motor, thanks to the increased power density. In addition, the lightening due to size reduction leads to an increase in mileage and the cost reduction. The hairpin winding motor has low coil heat, good energy efficiency, and convenient production automation process, which increases production efficiency and cuts down on defect rate.

The process of manufacturing a hairpin motor is carried out in the order of manufacturing a hairpin-shaped coil, inserting a hairpin coil, and welding a hairpin coil to complete the hairpin motor.
Currently, prototype hairpin motors for motorcycles and ultra-small electric vehicles have been completed, and in 2023, quality and price competitiveness will be secured through quality/productivity safety processes.

About Company

The company has secured the motor design technology, assembly technology and automated production process technology in EV car mobility, and has the production capacity of small home appliances, refrigerator parts, and clothing management equipment parts in eco-friendly manufacturing processes. Manufacturing capacity is prepared for overseas expansion because it has three manufacturing facilities and sufficient manpower.

To increase R&D competitiveness for EV motor commercialization, there are three teams in the R&D institute, which are research team, development team, and test team, which are focusing on not only performing government-funded R&D but also developing EV motor itself.

Since the hairpin winding motor is specialized in three-wheel, two-wheel, and small electric vehicles, the Southeast Asian market, which is in high demand for these reasonable and specific-purposed products, become a significant target country.
This company planning to export hairpin motor products to the Southeast Asian market. Therefore they hope to cooperate with commercialization partners who have their own business network in Southeast Asia's micro mobility motor industry.
