The YS-342026 series digital servo is a modular driver, consisting of a gear reducer, a brushless high-speed motor, and a control board package.
The motor and reducer are highly integrated, with a compact size, built-in temperature sensor, and support for multiple operating modes.
Equipped with a standard brushless high-speed motor, it has strong power, longer service life, and significantly improved precision and response speed.
The J288 model is an upgraded version of the S288 model, upgraded from engineering plastic gears and engineering plastic shells to metal gears and aluminum alloy shells, thereby enhancing heat dissipation, servo life, and impact resistance.
Can be widely used in various robot joints and power components such as robotic arms and dexterous hands.
The first choice for robot competitions, DIY creation, scientific research and education, and the robot field.
