CubeMars G80 KV60

The G80 KV60 is the fast winding of the CubeMars G80 gimbal motor. It delivers the same 1 Nm rated and 2.9 Nm peak torque as the KV30, but provides that torque at a rated speed of 1010 rpm on 24 V. Its no-load speed is 1300 rpm. For the G80 the manufacturer states 0.01° precision and a high slot-fill winding. The 315 g motor has no driver board and is used with an external FOC driver.

Key features

• Speed and torque together. It delivers 1 Nm rated torque at 1010 rpm, suiting systems that must turn large, heavy heads quickly.
• Low winding resistance. Phase to phase resistance is 450 mΩ and inductance 270 µH, against 1800 mΩ and 1100 µH for the KV30 winding.
• 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, so signal and power can be carried on continuously rotating axes.
• Waterproof and dustproof design. The manufacturer states high water and dust resistance but gives no protection rating on the G80 page.

Applications

Typical applications include continuously rotating radar and lidar heads, fast slewing vehicle-mounted sensor turrets, tracking cameras and autonomous driving perception modules that sweep a wide angle quickly.

Is it enough for your project?

The G80 KV60 delivers 1 Nm continuous and 2.9 Nm peak torque. On rotating heads and gimbals the torque demand is mostly set by how far the center of gravity of the load sits from the axis. For example, a 2.5 kg sensor head with its center of gravity 3 cm off the axis needs about 0.74 Nm of static torque (2.5 × 9.81 × 0.03). That load stays within the rated torque.

Rated current is 5.6 A, peak current 16.3 A and the torque constant 0.178 Nm/A, so the driver and power supply should be sized for these currents. If the axis turns slowly, the G80 KV30 gives the same torque with less current.

How it compares to similar models

• G80 KV30. Same housing and torque figures. Its no-load speed is 650 rpm and its rated current 2.8 A.
• G60 KV55. One size down, also a fast winding. It gives 0.6 Nm rated torque and 1140 rpm no-load speed and weighs 226 g.
• GL80 KV30. The GL model with the same diameter. Its page also lists the KV60 winding with the same values as the G80 KV60, with Kv given as 54.5 rpm/V. The GL80 page states a size of Ø87 × 22.3 mm, a 30 mm bore and IP45 protection.

Frequently asked questions

What is the difference between KV60 and KV30?

The torque figures and the housing are the same. The KV60 turns faster (1300 rpm no-load against 650 rpm for the KV30), in return it draws more current for the same torque (5.6 A against 2.8 A).

Is a driver included?

No. The product page lists the driver board option as "no". The motor is used with an external FOC driver that must handle the 16.3 A peak current.

Can it rotate continuously through 360 degrees?

The motor is brushless and the large center hole is suited to a slip ring. With signal and power routed through a slip ring the axis can rotate continuously.

What are its dimensions?

The manufacturer does not give dimensions on the G80 page. Check the 2D drawing PDF and the CAD model for mounting dimensions.
