Parallax (Futaba S148) continuous rotation servo.

Overview

The Parallax (Futaba S148) continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. It can be controlled directly by a microcontroller without any additional electronics, which makes it a great actuator for robotics projects. The servo includes an adjustable potentiometer that can be used to center the servo and comes with a star-shaped servo horn and an 11″ (270 mm) lead.

Specs

  • Power: 4.8 – 6 V
  • Top 6 V speed: 50 RPM (with no load)
  • Torque: 2.7 kg-cm/38 oz-in at 6 V
  • Weight: 43 g/1.5 oz with servo horn and screw
  • Size (L x W x H): 40.5 mm x 20.0 mm x 38.0 mm / 1.60" x 0.8" x 1.50"
  • Control interface: RC servo pulse width control, 1.50 ms neutral
  • Manual adjustment port

This servo is compatible with our servo controllers and our servo wheels and sprockets.
