SB3290SG-BE High Torque, High Voltage Brushless Servo (Black Edition)
SKU:
The Savox SB3290SG-BE is a heavy-duty, standard-sized brushless servo engineered for high-load applications that demand robust holding power and long-term reliability. Driven by an efficient brushless motor and managed by a high-resolution 32-bit digital processor, it delivers exceptionally smooth positional accuracy and reliable tracking. This "Black Edition" actuator features a stealthy all-black finish and a rugged steel gear train housed within a heat-dissipating aluminum center case, making it a dependable, no-nonsense choice for demanding linkages, steering setups, or heavy mechanical joints.
How Far Will This Servo Rotate?
The answer to this question is partially dependent on what you are using to control the servo.
Click for a quick video explanation.
With an Average Radio System:
90°
Using the PWM signal range provided by most R/C transmitters (1050–1950 µsec), this servo rotates approximately 90°. This operating range is common throughout the hobby industry, but it does not utilize the servo's full available travel.
Wide Signal Controllers:
170°
When driven with the maximum PWM signal range (650–2350 µsec), this servo can achieve approximately 170° of rotation. This wider signal range can be generated by devices such as ESP32s, Arduinos, Raspberry Pi servo controllers, and other programmable servo drivers. Signals outside this range are not recommended as they may result in reduced performance, erratic operation, or no response.
