Hairpin motor represents a breakthrough in electric drive technology, featuring advanced flat‑wire hairpin winding that significantly enhances performance compared to traditional round‑wire motors.

This innovative design enables higher power density, greater energy efficiency, and outstanding heat dissipation, ensuring stable operation even under continuous high‑load conditions.
With a compact footprint and consistent high‑speed output, hairpin motors are ideally suited for high‑performance electric motorcycles, light electric vehicles, and a wide range of direct‑drive applications that demand dependable, efficient, and long‑lasting power.
Hairpin motor QSD155-36, rated at 5000W with a peak power of 15000W, operates at 72V DC and delivers a maximum efficiency of ≥93%.

It features a rated speed of 6000RPM (up to 8000RPM with flux weakening) and a peak torque exceeding 45Nm, housed in an IP67-rated, naturally cooled package.
Built with 4 pole pairs and a 36H, 48SH grade magnet, this PMSM motor offers reliable, high-speed performance for demanding electric mobility applications.
Hairpin gear motors build upon the strengths of hairpin motors by integrating a high‑precision gear reduction system.
This combination delivers strong low‑speed torque, exceptional load‑carrying capability, and smooth operation, while retaining the core benefits of hairpin winding technology.
Engineered for heavy‑duty and high‑torque scenarios, they are perfect for electric tricycles, three‑wheelers, AGVs, logistics vehicles, and various industrial machinery that require reliable, powerful, and cost‑effective drive solutions.
Hairpin gear motor QSJ155-36, with a 5000W rated power and 12.5kW peak output, combines the hairpin motor with a 1:2.94 gear ratio to deliver a rated shaft torque of 17.5Nm and peak torque of 141Nm.

Operating at 72V DC, it provides a rated shaft speed of 2075RPM (peak 2720RPM) with a maximum efficiency of ≥92%.
The air-cooled, IP67-rated unit weighs 10kg and is designed for heavy-duty applications requiring strong low-speed torque and reliable performance.
Both hairpin motors and hairpin gear motors are designed for reliability, energy savings, and durability.
They address the diverse demands of today’s electric mobility and industrial drive sectors, offering scalable, high‑performance solutions that support sustainable development and meet global quality standards.
