Features:
- Improved front cover, better heat dissipation
- Rotor with more beautiful star design
- Increased the rigidity of the rotor and shell, reduce vibration, can withstand more loads.
- Adopt tile magnets with higher grade
- Higher efficiency laminations
- Reduce the air gap of the stator and rotor, increase efficiency
- Thicker high temperature enameled wire, improved insulation and impact resistance
- Compare EA with CA at same level, the power increased 10-20%, and efficiency increased 3-5%.
- More options for KV value, suitable for practical use
- Add XM2838EA, XM4255EA which models CA do not have.
- Motor mounting holes and shaft diameter compatible with CA Series
- Accessories compatible with the CA series (except for new models)
- 8mm propeller mount with the thinner threads, propeller not easy to loose.
