Hairpin preformed winding flat motor, namely 270 series, is independently developed by R&D team of Shunqu Power and has been officially mass-produced in mid-2022. Axial embedding of flat wire preformed winding, high slot fill factor and short winding end size. Higher motor efficiency and being adapted to more transmission systems with different power. Low material cost and mature supplier system. Mature mass production equipment, low production line investment, high production efficiency.

Because of compact winding process, multi-pole design and very short winding end, the volume density and power density of the motor are very high, the volume density can reach 65N/L, the power density can reach 5kW/kg, the motor cost is relatively low, and the slot fill factor is high, suitable for P2 starting generator below 1000rpm.
