Dualsky DSXM51686 ECO 4130C 290kv Brushless Motor

ECO V2 has made great improvements in many respects. It brought new electromagnetic design, more competitive performance and efficiency, long-time endurance and water-proof. This ECO 4130C brushless motor is designed to suit 90E-110E models and double wing 70e models, for example, Sebart Miss Wind.

Features

• Motor structure strength increased by 25%
• Optimised stress distribution and strength increased but it did not increase the weight.
• High strength and high toughness main shaft (HRC48)
• The rotor limit adopts 2 insurance modes of circlip and stainless steel chocks
• High temperature resistant, high toughness epoxy glue the impact resistance increased about 10G, and the survival ability is greatly improved.
• High precision double sides dynamic balancing
• Adopt NMB ball bearing, durable and low noise. ECO 41 and bigger, equipped with 3 ball bearings
• Optimised heat dissipation ways
• Motor working life significantly increased by 50% (same load and working environment)
• Modular design: main shaft, case and accessories (propeller mount and motor mount) are all compatible with the upcoming EA series. Besides, the design of propeller mount is completely implanted from GA series.
• Up to 500V insulation level. The stator is coated with insulating coating and completely insulated after winding.
• Waterproof splash. Rustproof main shaft, coil soak insulation, electrophoresis components and coated magnets make ECO V2 waterproof, and no problem working in wet or rain environment.
