FG270 is a coaxial flat motor composed of a permanent magnet inner rotor and a single-tooth winding stator. Its performance is significantly higher than that of well-known competitors in the market. It has compact mechanical design, expandable production, small torque fluctuation, high work efficiency, low raw material cost, and the supplier system is mature.
FG270 has a very short axial dimension and is easy to integrate with the power transmission system. It is especially suitable for the P2 hybrid power system. It is currently the only mass-produced coaxial flat motor that can be used in the P2 hybrid configuration in China. With the explosive growth in sales of P2 hybrid models, this motor will give priority to seizing the market with mature technology and excellent cost performance.
