Product Overview

Smooth, high-density torque

The CubeMars RO60 KV115 is a frameless outrunner torque motor for direct-drive robotic joints. It runs on 48 V and delivers about 0.8 Nm continuous and up to 2.4 Nm peak torque from a 248 g body.

Ultra-low cogging torque gives smooth low-speed motion, while a large hollow through-hole allows flexible cable routing or shaft swapping. Standard Hall and temperature sensors provide accurate commutation and real-time thermal protection for cobot arms, exoskeletons and medical robots.
