1. Combined with 0.2 steel plate, the H550 motor not only has high , but also high efficiency.
2. Motor adopts high magnetic energy product N45SH magnetic steel, temperature up to 150°.
3. Grade 6 magnetic steel forms a powerful magnetic field. Suitable for RC helicopter. Better of copper wire from damage.
4. The motor adopts 220 high‑temperature enameled wire, and the outlet bushing is changed to carbon fiber shell, which is strong in fire prevention.
5. High‑speed motors are a test of bearings and shafts. Therefore, on the H550 motor, we installed original imported bearings, and the shaft material was changed to HRC 55 degree stainless steel, which improved the defects of the previous shaft.
