Product Overview
Smooth, high-density torque
The CubeMars RO80 KV105 is a frameless outrunner torque motor built for direct-drive robotic joints. Running on 48 V it delivers about 1.3 Nm continuous and up to 4 Nm peak torque from a compact 352 g body, with a torque density around 11.4 Nm/kg.
Ultra-low cogging torque gives smooth low-speed motion, while a large hollow bore allows through-hole wiring or direct shaft coupling. An aluminium alloy housing adds impact and corrosion resistance, and integrated Hall and temperature sensors provide accurate commutation and thermal protection.
