The DSServo DS3235SSG 35kg coreless waterproof digital servo uses high-precision steel gears and potentiometers, a high-resolution digital chip and waterproof rubber seals. Its CNC aluminium middle shell is meant to give stable performance and a long working life.
The listing describes a 35kg full-metal-gear standard servo suitable for RC off-road vehicles, crawlers, mechanical arms, robots, boats and giant-scale aircraft. The coreless motor is described as durable and responsive, with strong anti-interference ability, low noise and fast heat dissipation.
The angle range is selectable at 180 or 270 degrees using a 500 to 2500 microsecond pulse, and the listing says the output shaft can be rotated through 360 degrees when the power is off.
Dual ball bearings: smooth rotation and durability.
CNC aluminium middle shell: heat dissipation and stability.
Steel gears with hard anodising: high-precision metal gears.
Coreless motor: responsive, low noise and fast heat dissipation.
IP67 waterproof: rubber-sealed screws and housing.
Selectable 180 or 270 degrees: 500-2500us pulse range.
Free accessories: 25T servo arm and accessory set.
A hobby servo combines a small motor, a gearbox and a position sensor with control electronics. You send it a pulse every 20 milliseconds or so, and the width of the pulse tells it where to go: about 1.5 milliseconds is centre, with roughly 1.0 and 2.0 milliseconds at the ends. The servo drives its output shaft until the sensor says it has reached the commanded position, then holds it against the load.
Digital servos process the signal with a microcontroller and drive the motor at a much higher rate than analogue servos, which gives faster response, a smaller dead band and stronger holding torque. Metal gears cope better with shock loads than plastic ones, and ball bearings keep the shaft smooth and reduce wear.
Always power a servo from a supply that can deliver its peak current, not from a weak receiver port, and keep the linkage free so the servo never strains against a mechanical stop. A stalled servo draws a large current and can overheat within seconds.
