CubeMars G100 KV10

The G100 KV10 is the largest and highest torque gimbal motor in the CubeMars G series. On 24 V it delivers 3 Nm rated and 7.7 Nm peak torque and weighs 698 g. Its no-load speed is 223 rpm and its rated speed 130 rpm. For the G100 the manufacturer states 0.01° precision and a high slot-fill winding. The motor has no driver board and is used with an external FOC driver.

Key features

• Highest torque in the series. With 3 Nm rated and 7.7 Nm peak torque it can carry heavy payloads without a gearbox. The torque to weight ratio is 11.03 Nm/kg.
• Very high torque constant. The torque constant is 1.030 Nm/A. It delivers its 3 Nm rated torque at 2.9 A rated current, keeping the load on the driver and cables low.
• High insulation strength. The insulation high-voltage test is 1000 V 5 mA/2 s and insulation resistance is 10 MΩ at 1000 V.
• Large center hole. The large bore suits cable routing and electrical slip ring integration.
• Waterproof and dustproof design. The manufacturer states high water and dust resistance but gives no protection rating on the G100 page.

Applications

Typical applications include the pan axes of heavy cinema camera gimbals, large surveillance and thermal camera turrets, heavy radar heads and large perception modules on autonomous vehicles.

Is it enough for your project?

The G100 KV10 delivers 3 Nm continuous and 7.7 Nm peak torque. On a gimbal motor the torque demand is mostly set by how far the center of gravity of the load sits from the axis. For example, an 8 kg camera turret with its center of gravity 3 cm off the axis needs about 2.35 Nm of static torque (8 × 9.81 × 0.03). That stays within the rated torque, and the peak torque leaves margin for wind and sudden moves.

Rated current is 2.9 A and peak current 7.8 A. Rotor inertia is 2310 g·cm², the highest in the G series. If you need a faster, lighter axis, the G80 KV30 or G80 KV60 may be a better fit.

How it compares to similar models

• GL100 KV10. The table values of this GL model with the same diameter match the G100 KV10 (3 Nm rated, 7.7 Nm peak, 698 g). The GL100 page also gives a size of Ø106.8 × 34.2 mm, a 30 mm bore and IP45 protection. Its table lists Kv as 9.3 rpm/V.
• G80 KV30. One size down. It gives 1 Nm rated and 2.9 Nm peak torque, is faster at 650 rpm no-load and weighs 315 g.
• G80 KV60. It gives the same 1 Nm rated torque at a rated speed of 1010 rpm, suiting rotating heads where speed matters more than torque.

Frequently asked questions

Is a driver included?

No. The product page lists the driver board option as "no". The motor is used with an external FOC gimbal driver.

What is the difference between the G100 and the GL100?

The electrical figures on both pages are the same. The GL100 page states IP45 protection, the motor size and the package size. The G100 page gives no dimensions, so check the 2D drawing PDF for mounting dimensions.

How fast does it turn?

On 24 V the no-load speed is 223 rpm and the rated speed 130 rpm. The motor is designed for slow, powerful motion.

Can a slip ring be fitted?

Yes. The large center hole is designed for slip ring integration and cable routing.
