Technical Drawing
The CubeMars GL30 KV290 gimbal motor is a compact brushless motor specifically designed for gimbals, aerial photography stabilizers, radar systems, and other low-speed, high-precision applications. Featuring ultra-lightweight construction, high torque density, and low cogging performance, this motor also includes a large center through-hole, enabling easy routing of cables or integration with slip rings for signal and power transmission. With support for speed and position loop control, it delivers responsive and precise performance, making it an ideal choice for high-performance gimbal systems.
Motor Dimensions: Ф34.5*15.7mm
Through-hole Diameter: 6mm
Motor Weight: 41g
Peak Torque: 0.28Nm
No-load Speed: 3060rpm
Ultra-lightweight: Weighs only 41g, ideal for lightweight gimbals or airborne equipment
Low Cogging / Smooth Torque: Low cogging design ensures smoother and finer motion control
Large Center Through-hole: Spacious bore allows for easy cable routing (signal, power, etc.) and compatibility with slip rings
High Reliability: IP45-rated for dust and water resistance, suitable for outdoor or demanding environments
High Torque Density: Delivers 0.28 Nm peak torque despite its lightweight structure, providing strong output in a compact form
