CubeMars GL40 KV70

The GL40 KV70 is a brushless gimbal motor from the CubeMars GL series, designed for gimbals, aerial photography stabilizers, radar rotating heads and autonomous driving scanning modules. It delivers 0.25 Nm rated and 0.5 Nm peak torque and weighs 107 g. Its light build, precision and low noise make it a good fit for applications that need stable, smooth output over long periods.

Key features

• Low noise, low cogging. The optimized electromagnetic structure reduces cogging for smoother output and faster response.
• 8 mm hollow shaft. Signal and power cables pass through the center, and it can be combined with slip rings and other rotating assemblies.
• Light build. At 107 g it lowers total system weight and saves installation space.
• IP45 protection. Resistant to dust and water splashes, it can be used outdoors and in demanding mechanical environments.
• AlexMos compatibility. It can be used with AlexMos gimbal controllers.

Applications

Typical applications include mid-size camera gimbals, aerial photography stabilizers, radar scanning systems and autonomous driving perception modules where smooth, stable motion is critical.

Is it enough for your project?

The GL40 KV70 delivers 0.25 Nm rated and 0.5 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 1 kg camera or sensor with its center of gravity 2 cm off the axis needs about 0.2 Nm of static torque (1 × 9.81 × 0.02). That load stays within the motor's rated torque.

It runs on 16 V, with a no-load speed of 1015 rpm and a rated speed of 430 rpm. Rated current is 1.62 A and peak current is 3.3 A. If you need more peak torque the GL40II KV82.5 may be a better fit, and for heavier loads, the GL60 KV25.

How it compares to similar models

• GL40II KV82.5. It gives the same 0.25 Nm rated torque with a higher peak of 0.68 Nm. It weighs 125 g, is taller at Ø46.1 × 33.5 mm and has a no-load speed of 1388 rpm.
• GL35 KV100. At 16 V it gives 0.15 Nm rated and 0.46 Nm peak torque. It is lighter at 90 g and has a 6 mm center hole.
• GL60 KV25. At 24 V it gives 0.6 Nm rated and 1.75 Nm peak torque. It weighs 230 g and has a 20 mm center hole.

Frequently asked questions

Is the driver included?

No. The GL40 is the motor only. It is used with a gimbal controller such as AlexMos or with a FOC driver.

Does it have an encoder?

This product is the motor without an encoder. The manufacturer also offers an encoder option for the GL40.

How big is the center hole?

The hollow shaft is 8 mm in diameter. It is used for a cable bundle or a slip ring.

In the box

• GL40 KV70 gimbal motor
• 150 mm connection cable

Box size 109 x 82 x 42 mm.
