Dualsky ECO 4120C 500kv Brushless Motor
The 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 4120C 500kv motor is designed to be the electric equivalent of a .46 – .55 2-stroke engine.
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.
