CubeMars GL80 KV30

The GL80 KV30 is a high-precision brushless gimbal motor from the CubeMars GL series, designed for gimbals, rotating scanning modules and autonomous driving perception systems. It is 87 mm in diameter but only 22.3 mm high. It delivers 2.9 Nm peak torque from 315 g, and its 30 mm center hole leaves room for thick cable bundles and slip rings.

Key features

• 30 mm hollow shaft. Signal and power cables pass through the center, or a slip ring fits inside. It suits complex wiring and continuous rotation systems.
• Smooth, stable motion. Electromagnetic optimization reduces cogging torque for stable, smooth motion control.
• High torque to weight ratio. It delivers 1 Nm rated and 2.9 Nm peak torque, a torque to weight ratio of 9.21 Nm/kg.
• IP45 protection. Resistant to dust and water splashes, it can be used in dusty or outdoor environments.
• Broad control compatibility. It works with various gimbal controllers and driver solutions. The insulation is tested at 1000 V.

Applications

Typical applications include heavy camera gimbals, radar units, autonomous driving LiDAR scanners and rotating platforms that need precise positioning.

Is it enough for your project?

The GL80 KV30 delivers 1 Nm rated and 2.9 Nm peak torque. In a gimbal, the required torque depends on how far the load's center of gravity sits from the rotation axis. For example, a 3 kg camera or LiDAR with its center of gravity 3 cm off the axis needs about 0.88 Nm of static torque (3 × 9.81 × 0.03). That load stays within the motor's rated torque.

It runs on 24 V, with a no-load speed of 650 rpm and a rated speed of 450 rpm. Rated current is 2.8 A and peak current is 8.2 A. For a lighter load the GL60 KV25 may be a better fit, and for a heavier load, the GL100 KV10.

How it compares to similar models

• GL60 KV25. At 24 V it gives 0.6 Nm rated and 1.75 Nm peak torque. It has the same 22.3 mm height, weighs 230 g and has a 20 mm center hole.
• GL100 KV10. At 24 V it gives 3 Nm rated and 7.7 Nm peak torque. It weighs 698 g, measures Ø106.8 × 34.2 mm and has a no-load speed of 223 rpm.
• GL60II KV28. At 16 V it gives 0.6 Nm rated and 1 Nm peak torque, weighs 276 g and measures Ø70.5 × 33.6 mm.

Frequently asked questions

Are the driver and encoder included?

No. The GL80 is the motor only. The manufacturer states that it enables high-precision control when paired with an encoder. The driver and encoder are chosen separately.

How big is the center hole?

The hollow shaft is 30 mm in diameter, leaving enough room for thick cable bundles or a slip ring.

What voltage does it run on?

Rated voltage is 24 V. The speed, current and torque figures in the table are given for this voltage.
