Overview

The DSpower DS-R047 is a PWM servo motor for compact robot mechanisms, including humanoid robots, robotic arms, and desktop robots. It operates from 7.4–8.4 V DC and provides 280° ±10° operating travel with a 500–2500 µs pulse-width range. At 7.4 V, specified performance includes at least 1.8 kgf·cm stall torque and no-load speed of 0.05 sec/60° or less.

Features

Compact plastic-body configuration with an injection-molded gear set.
Stated clutch torque: 1.2 kgf·cm; the clutch structure is described as resistant to external impact and intended to help reduce overload-caused mechanical damage.
Specified output shaft: Ø4.85 mm × 40T.
Product material describes lower operating noise, high precision, smoother operation, flexible handling, and long service life.
Additional stated features include anti-burn and anti-shake characteristics, reduced tooth sweeping, and a cost-reduction plan intended to extend lifespan.
The clutch life is stated to be significantly extended compared with the first-generation DS-S006L.
