D60L180 120kv Waterproof Electric Motor 6000W for Efoil / Hydrofoil

The Hobiba D57L180-120KV is a compact, high-performance brushless motor engineered for marine propulsion systems where space and weight are at a premium. Featuring a slim 57mm diameter design with an 18N6P internal rotor configuration, it delivers up to 6kW of power and 10 N·m of torque within a remarkably small footprint. Its optimized magnetic circuit with a reduced air gap ensures higher flux density, resulting in more effective torque production and efficiency exceeding 85%. Fully rated IP68 for permanent submersion, this motor is the ideal power solution for integrating into sleek electric surfboards (eFoils), water bikes, compact pod drives, and underwater thrusters, offering a perfect blend of power, efficiency, and minimalist design.
