FS5109R High-Torque Continuous-Rotation Analog Servo With 10.2 kgcm Torque, Metal Gears and 55 RPM Speed

The FS5109R is a standard-size analog continuous-rotation servo designed for mobile robots, wheeled platforms, conveyor mechanisms, RC projects, educational robotics, and applications requiring bidirectional rotary motion. At 6V, it delivers up to 10.2 kg.cm stall torque with a no-load speed of approximately 55 RPM. Unlike a conventional positional servo, the FS5109R rotates continuously in either direction, with the PWM signal controlling rotational direction and speed rather than commanding a specific shaft angle.

The servo combines a metal gear train, metal-brush motor, dual ball bearings, 25T output spline, and nylon + fiberglass housing for reliable mechanical transmission in robotics and RC applications. It operates from 4.8V to 6V and uses standard RC-style PWM control from 500-2500us, with approximately 1500us serving as the stop command. This makes it straightforward to integrate with compatible servo controllers, Arduino, ESP32, Raspberry Pi control hardware, and other embedded systems.

Key Features

  • 10.2 kg.cm Stall Torque at 6V: Provides strong peak torque for mobile robots and rotary mechanisms.
  • 9 kg.cm Stall Torque at 4.8V: Maintains substantial torque at the lower rated operating voltage.
  • 360deg Continuous Rotation: Rotates continuously without conventional angular-position limits.
  • 55 RPM At 6V: Provides the specified no-load rotational speed at 6V.
  • 50 RPM At 4.8V: Supports continuous motion at the lower rated supply voltage.
  • Bidirectional Rotation: PWM commands below or above the neutral pulse determine CW or CCW operation.
  • 1500us Stop Position: Approximately 1500us commands the servo to stop rather than move to a physical centre position.
  • 500-2500us PWM Range: Supports standard pulse-width control for speed and direction.
  • Analog Control Electronics: Uses an analog comparator amplifier for conventional RC servo operation.
  • Metal Gear Train: Provides durable mechanical transmission for higher-load applications.
  • Metal-Brush Motor: Uses a brushed motor suited to continuous rotary operation.
  • Dual Ball Bearings: Support smoother shaft rotation and improved mechanical stability.
  • 25T Output Spline: Uses a standard 25-tooth spline for compatible servo horns and attachments.
  • Nylon + Fiberglass Case: Provides a strong yet lightweight standard-size servo housing.
  • POM Servo Horn: Supports compatible mechanical linkage and drive-wheel installation.
  • 10us Dead Band: Provides the specified neutral-control dead-band width.
  • Standard 3-Wire Interface: Uses power, ground, and PWM signal connections for straightforward integration.
  • Continuous-Speed Control: Suitable for applications where rotational speed and direction are more important than absolute angular positioning.
