D90L96-150KV High-Performance Water-Cooled Outrunner Motor

D90L96 Water-cooled Quanly 20V 36V 335kv 20kw Brushless Outrunner Motor

The Hobiba D90L96-335KV is engineered for the pursuit of extreme speed, offering the highest KV rating in the D90L96 series. Designed for 6-10S voltage systems (20-42V), it spins up to 14,070 RPM, delivering 23.5kW of peak power for applications where maximum velocity is the primary goal. This motor is ideal for lightweight, high-speed electric race vehicles, performance aircraft, and other platforms where minimizing rotational inertia and maximizing RPM are critical. Despite its focus on speed, it retains the series' hallmarks of high efficiency (92%), advanced cooling, and rugged construction.
