Overview
The Kpower RD13T is a dual-axis robotic servo motor for desktop, bio, education and service robots. Its coreless motor and magnetic encoder support controlled joint movement through a 180° travel range. At 7.4 V, it provides 13 kg·cm stall torque and a no-load speed of 0.24 s/60°. The 46 g unit measures 44.4 × 22.7 × 25.9 mm for integration into compact robot mechanisms.
Features
- Dual-axis robotic servo design for articulated mechanisms.
- Coreless motor with magnetic-encoder position sensing.
- Metal gears, plastic case and two ball bearings (2BB).
- 180° travel angle, with customization stated for the travel range.
- PWM, TTL and RS-485 listed as control protocols.
