Mini servo drive SPT Servo SPT17HV

Order the SPT Servo SPT17HV mini servo for drone - choose compact and powerful precision!

Mini Servo SPT Servo SPT17HV for Drone is a small but very powerful actuator. It is designed to control lightweight mechanisms in confined spaces. This servo drive provides high speed and positioning accuracy. You can use it to rotate the camera, control the compartment door, or control the trimmer. This is the ideal solution when compactness and performance are important.

This model uses high voltage technology (High Voltage - HV). This allows operation from a 7.4V power supply, which increases speed and torque. The internal motor and gearbox are made of quality materials. A feedback system via a potentiometer ensures precise angle determination. You get a reliable and responsive drive for your project.

• Compact size and light weight for integration into small-sized systems.

• High operating voltage (HV) up to 7.4V for increased speed and torque.

• Metal gearbox and double ball bearing for durability and precision.

• High rotation speed and torque for your size.

• Standard size and mounting for easy replacement and installation.

How does a miniature high power servo drive work?

The servo receives a PWM signal from the receiver or flight controller. The pulse width determines the target angle of rotation of the output shaft. The built-in electronic board compares the reference with the current position. The current position is read from a potentiometer mechanically connected to the shaft. If there is a mismatch, the board supplies power to the motor and it turns the shaft.

The gearbox reduces high engine speeds, increasing torque. Metal gears can withstand heavy loads without damage. When the specified angle is reached, the engine stops. The system continually adjusts the position to keep the shaft in place. This ensures precise and powerful control of the mechanism.

Technical characteristics and practical application

Model SPT17HV is a standard size in the mini servo class. Its dimensions are usually about 23x12x29 mm. Weight is approximately 17-18 grams, which is very small for such power. Operating voltage: 6.0V – 7.4V (optimally 7.4V). Rotation speed: 0.08 sec/60° at 7.4V. Torque: 2.8 kg cm at 7.4V. The gearbox is made of metal, the shaft is mounted on two ball bearings.

The servo drive functionality includes standard three-wire control. Signal wire (usually orange or yellow), power (+) and ground (-). It is compatible with all common receivers and controllers. Some versions may have Teflon wires for increased flexibility. Installation flanges and horns are included in the kit for installation and load connection.

This servo is great for a variety of applications on drones and models. Controls the rotation of the FPV camera for a view along the flight path. Drive mechanism for releasing a small load or parachute. Controlling flaps or trim tabs on flying wings. In ground robots to rotate sensors or grippers. Any application that requires precise angular movement in a small form factor.

Installation of the servo is simple thanks to standard mountings. It is secured in the seat using two or four screws. The desired horn or lever is installed on the output shaft. Three wires are connected to the control channel on the receiver or controller. It is important to provide a stable 7.4V supply to realize its full potential. When used with a flight controller, the appropriate output is configured.

The servo drive is compatible with most radio equipment. It works with Futaba, FrSky, Flysky and others. Can be controlled directly from Arduino or Raspberry Pi. Its reliability has been tested under vibration and overload conditions. High-quality assembly ensures a long service life even with active use.
