CubeMars RO60 KV115

The RO60 is a frameless outrunner torque motor. It gives fast response and stability on compact robot platforms.

Key features

• Ultra-low cogging torque. Roughly halved compared with motors in its class, so low-speed rotation is noticeably smoother.
• Wide hollow shaft. Plenty of room at the center for cables and shaft integration.
• Interchangeable shaft. By changing the shaft, the same motor fits different mechanical interfaces.
• Hall and temperature sensors. Position and temperature feedback come from inside the motor.

Applications

Typical applications include exoskeletons, collaborative robot arms, medical devices and aerospace applications.

Is it enough for your project?

The RO60 is a frameless torque motor. The bearing, encoder and driver are part of your design. It delivers 0.8 Nm continuous and 2.4 Nm peak torque from a body weighing 248 g. Its wide hollow shaft lets you pass cables, run a drive shaft through it or connect it directly to a gearbox.

In direct drive it is enough for camera axes and light rotary platforms. In robot joints it is usually paired with a gearbox. For example, with a 10:1 planetary gearbox you get about 8 Nm of continuous torque at the output, excluding losses.

How it compares to similar models

• RO60 Lite KV115. Gives the same torque and speed values at 195 g and 15 mm tall. Its rotor inertia is lower (800 g·cm²).
• RO80 KV105. A higher class with 1.3 Nm rated and 4 Nm peak torque, weighing 352 g.
• RI60 KV120. An inrunner alternative with 0.57 Nm rated torque, weighing 155.9 g.

Frequently asked questions

Is the driver included?

No. With frameless motors the driver, encoder and bearing are chosen by the user. You need a 48 V FOC driver with Hall input that can deliver at least 8.5 A continuous.

How does it differ from the Lite version?

Torque and speed values are the same. The standard version is 53 g heavier, 8 mm thicker and has higher rotor inertia (1,161 g·cm²). Higher inertia smooths out speed fluctuations.

Which sensors does it have?

Hall sensors and a temperature sensor are inside the motor and provide position and temperature feedback.

What is in the box?

Along with the motor you get a Ø1.8 × 8 mm locating pin and six M3 × 5 mm screws.

In the box

• RO60 KV115 frameless outrunner torque motor
• Ø1.8 x 8 mm locating pin
• M3 x 5 mm screw (6 pcs)

Box size 89 x 91 x 73 mm.

Integration

In frameless outrunner motors the rotor turns on the outside, which gives more torque at the same diameter. The flange, bearing, encoder and driver are designed by the user. Thanks to the wide hollow shaft, cables can pass along the axis.
