Xiaomi CyberGear Micromotor
Xiaomi CyberGear is a quasi-direct-drive joint actuator with a 7.75:1 reducer, integrated FOC driver and 14-bit single-turn absolute encoder, controlled over 1 Mbps CAN. At 24 V (16–28 V) it gives 4 N·m continuous, 12 N·m peak, 296 rpm no-load and 240 rpm at rated load, with 0.87 N·m/A and Class B insulation. Ø80.5 × 36.5 mm, 317 g.
