EMAX E3 Series 2306 1900KV Brushless Motor
by EMAX

The EMAX E3 Series 2306 1900KV Brushless Motor is a high-performance propulsion system precision-engineered for 5-inch FPV racing and freestyle drones. Designed to deliver an optimal balance of raw power and uncompromised efficiency, the E3 Series represents a significant step forward for pilots seeking a locked-in, ultra-responsive flight experience. The 1900KV variant is specifically optimized for high-voltage 3S to 6S LiPo power configurations, making it a go-to choice for modern 6S drone setups that demand explosive punch outs alongside smooth, predictable throttle resolution across the entire band.

At its core, the motor features a robust 12N14P framework paired with a durable 4mm bearing shaft that ensures long-term reliability and extreme resistance to harsh flight impacts. Generating a massive peak power rating of up to 1160W and managing a peak current of 46A, this motor provides the aggressive torque and thrust required to snap through tight racing gates or recover seamlessly from intense freestyle maneuvers. To keep weight to an absolute minimum without sacrificing structural strength, the E3 2306 utilizes a lightweight base design weighing a mere 29.4 grams. Completed with pre-soldered, heavy-duty 20AWG silicone lead wires spanning 120mm, this motor provides custom drone builders, commercial sUAS manufacturers, and university aerospace engineering teams with a premier, high-fidelity propulsion foundation.
