CubeMars G60 KV55

The G60 KV55 is the fast winding of the CubeMars G60 gimbal motor. It delivers the same 0.6 Nm rated and 1.75 Nm peak torque as the KV25, but on 24 V it reaches 1140 rpm no-load and 840 rpm rated speed. For the G60 the manufacturer states 0.01° precision and a high slot-fill winding. The 226 g motor has no driver board and is used with an external FOC driver.

Key features

• High speed at rated torque. It delivers its 0.6 Nm rated torque at 840 rpm, giving a much wider speed range than the KV25 for fast panning and tracking moves.
• Low winding resistance. Phase to phase resistance is 1200 mΩ and inductance 900 µH, against 5500 mΩ and 2720 µH for the KV25 winding of the same housing.
• Precise positioning. The manufacturer states 0.01° precision for the G series, with speed and position control modes.
• 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 G60 page.

Applications

Typical applications include camera gimbals with a fast pan axis, rotating radar and lidar heads, object tracking systems and autonomous driving sensor modules that change direction quickly.

Is it enough for your project?

The G60 KV55 delivers 0.6 Nm continuous and 1.75 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, a 1.5 kg sensor head with its center of gravity 3 cm off the axis needs about 0.44 Nm of static torque (1.5 × 9.81 × 0.03). That load stays within the rated torque.

Rated current is 2.93 A, peak current 8.9 A and the torque constant 0.205 Nm/A, so size your driver for these currents. If the axis turns slowly, the G60 KV25 gives the same torque with less current. For more torque at a similar speed, look at the G80 KV60.

How it compares to similar models

• G60 KV25. Same housing and torque figures. Its no-load speed is 516 rpm, its rated current 1.35 A and it weighs 230 g.
• G80 KV60. One size up. It gives 1 Nm rated and 2.9 Nm peak torque with 1300 rpm no-load speed and weighs 315 g.
• GL60 KV25. The GL model with the same diameter. Its page also lists the KV55 winding with the same values as the G60 KV55, with Kv given as 47.5 rpm/V. The GL60 page states a size of Ø69 × 22.3 mm, a 20 mm bore and IP45 protection.

Frequently asked questions

What is the difference between KV55 and KV25?

The torque figures and the housing are the same. The KV55 turns faster (1140 rpm no-load against 516 rpm for the KV25), in return it draws more current for the same torque.

Is a driver included?

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

Can a slip ring be fitted?

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

What are its dimensions?

The manufacturer does not give dimensions on the G60 page. Check the 2D drawing PDF and the CAD model for mounting dimensions.
