Brief Overview

The Emax ECO II Series 2807 3-6S 1300KV motor is an updated brushless design created specifically for 7-inch propellers, heavy-lift platforms, and long-range drones. Emax engineers have re-evaluated the motor's architecture to combine enhanced performance, reliability, and an attractive price point in one series, making the ECO II an excellent choice for enthusiasts and professionals.

Description and Purpose

The ECO II 2807 series is ideal for applications requiring high thrust and stable performance under load: 7" propeller freestyle, heavy lifters, and long-flight drones. The new rounded bell with strengthened mounting points increases mechanical strength, while the mirror polish provides an aesthetic and modern look.

Technical Features and Advantages

Key advantages of the ECO II series:

• Updated design with a rounded bell and reinforced mounting points for increased durability.
• Mirror-polished casing for durable protection and a neat appearance.
• N52SH magnets (replacing N48) provide faster throttle response and higher maximum RPM.
• Increased torque and enhanced thrust for more precise control and pilot flexibility.
• Precise 12mm EZO ball bearing for maximum smooth operation under various loads.
• Motor mounting size: 19x19 mm, compatible with a wide range of frames and mounts.
• Steel shaft for longer lifespan during intensive use.
• Multi-strand winding for reliable power and resistance to peak loads.
• 200mm long silicone wires with 18 AWG cross-section for reliable connection to ESCs.

Package Contents

The kit includes:

• Emax ECO II 2807 brushless motor.
• 5 M3×10 screws for motor mounting.
• 5 M3×8 screws for alternative mounting.
• 1 M5 aluminum lock nut for propeller.
• 1 washer and screw for shaft retention.

Detailed Design Description

The completely redesigned internal architecture of the ECO II enhances strength and reliability: rounded edges and reinforced mounting points reduce stress concentration and increase durability during aggressive maneuvers. The use of N52SH magnets improves the efficiency of electrical to mechanical energy conversion, evident in faster throttle response and higher peak RPM. The large, precise 12mm EZO bearing ensures smooth rotation even under significant loads, while the steel shaft along with multi-strand winding extends the motor's lifespan under intensive use.

The motor is compatible with 3S–6S batteries and has a 1300KV rating, allowing for an optimal balance between rotational speed and thrust for a wide range of tasks. If you need a reliable motor for 7" propellers with good thrust, stable performance under load, and a long service life — the Emax ECO II 2807 3-6S 1300KV is an excellent choice.
