ST3025 40kg.cm Metal Serial Bus Servo, High Precision And Large Torque, With Programmable 360 Degrees Magnetic Encoder and Brushless Motor
This product is a dual-axis serial bus servo with high torque. It incorporates a 360° high-precision magnetic encoder, allowing for angle control within a 360° range. The case is manufactured using high-precision CNC machining techniques. It is driven by a brushless motor, significantly increasing its lifespan and reliability. It can be controlled programmatically, allowing any angle to be set as the servo’s middle position. It can also be switched to continuous rotation speed mode or stepper motor mode. It supports absolute angle control of up to ±7 revolutions (revolution count is not saved in case of power loss). There are two connectors on top of each servo, allowing the servos to be used in series. In theory, it is possible to control up to 253 bus servos simultaneously, with each servo providing information about its current angle, load, voltage, mode, and other details. This product is suitable for robot projects that require closed-loop control, such as robotic arms, hexapod robots, humanoid robots, and wheeled robots.
