45kg Torque Coreless Waterproof Servo

This waterproof high-torque coreless servo comes with all-metal gears and aluminium shell, which makes it stronger, more wear-resistant, and more durable. The circuit board is laminated and sealed with a waterproof gasket and breathable composite waterproof glue so that the heat generated by the circuit board can be dissipated freely, and the water medium cannot enter, so as to achieve the IP67 waterproof effect. There is a built-in rotation driver that ensures the precise control of the running angle, offering more accurate, stronger, more stable, and quieter motion.

Since the PWM frequency controlled by the motor is relatively high, the jitter of the servo is very small after the load is applied – almost no control sound can be heard. This could be an excellent choice for multi-joint robot projects.

There is no limit inside the servo so it can rotate 360 degrees without getting stuck. With up to 180 degrees controlling angles, the servo features high accuracy and a long lifespan. The internal pulse lock function allows locking action with only transmitting one PPM pulse, which reduces the processor’s controlling consumption and extends the servo’s service life.

This servo features up to 180 degrees rotation angle within the pulse range of 500-2500μsec and 45kg.cm stall torque at 8.4V working voltage. It is suitable for professional development and research scenarios, or remote controlling applications such as DIY robot cars or ships.
