Technical Drawing
The CubeMars GL40 KV70 gimbal motor is a brushless motor from the CubeMars GL series, specifically designed for gimbals, aerial photography stabilizers, radar rotating heads, and autonomous driving scanning modules. It features a large hollow shaft structure, low cogging torque design, and an IP45 rating for dust and water resistance. With a rated torque of approximately 0.25 Nm and a peak torque of 0.5 Nm, the motor weighs only 107 g. Renowned for its lightweight construction, high precision, and low noise, it is ideal for long-duration operation requiring stable and smooth output.
Motor Dimensions: Ф46.5*21.5mm
Through-hole Diameter: 8mm
Motor Weight: 107g
Peak Torque: 0.5Nm
No-load Speed: 1015rpm
Ultra-lightweight Structure: Weighs only 107 g, facilitating system weight reduction and saving installation space
Large Hollow Shaft Design: Enables passage of signal and power cables, supporting integration with slip rings and other complex rotating assemblies
Low Cogging Torque Design: Optimized electromagnetic structure minimizes cogging, resulting in smoother output and improved responsiveness
IP45 Protection Rating: Dust- and splash-resistant, suitable for outdoor or demanding mechanical environments
High-precision Motion Control: Ideal for gimbals, radar scanning systems, and autonomous driving perception modules where smoothness and stability are critical
