Servo Robot Arm

Servo Robot Arm

The servo robot arm is mainly used for injection molding machine. We have 3 axis servo and 5 axis servo. The servo robot arm is normally working with horizontal injection molding machine, which can reduce the labor cost and improve the working condition and make sure the safety production. It can improve the production efficiency of the injection molding machine, stabilize the product quality, reduce the waste rate, reduce the production cost, enhance the competitiveness of enterprises and other aspects to play an important role, high accuracy, good stability, convenient operation,

What is a Servo Robot Arm?

Servo robot arms are robotic arms that have a programmable mechanism and are servo motor-driven. They have a device called an actuator in order to supply enough force and lift joints, perform sorting and gripping functions. A common robotics-oriented actuation mechanism is a servo or a stepper. Also, a motor driver, current sensor, MCU, and an encoder are all integrated into a servo motor control module.

Variety of Functions

Servo robot arms are used specifically for different kinds of industrial applications since these applications can’t be done by a regular human being. They can make your daily tasks easier and more accurate. They can perform various functions such as:

    • material handling
    • palletizing
    • assembling
    • sorting
    • gripping
    • other functions
Various Features & Benefits

Movement Flexibility

The servo robot arms have 6° of freedom—almost as much as a human’s arm. Their servo motors that are embedded into joints allow an accurate angular displacement over a range of -360 to +360°.

The engines also guarantee the work tool’s positioning with an accuracy of a thousandth degree.

To increase the arm’s flexibility, its configurations and designs can be changed since they have a modular construction.

High Torque Density

The torque output of the brushless AC motor can be multiplied by about one hundred thanks to built-in metal gearheads. It can be multiplied without affecting the overall size of servo.

Moreover, the underlying strain-wave technology also has the advantage of almost little backlash, which reduces efficiency losses.


The controllers are in charge of the governing procedure. In order to report the execution of devices and receive commands, the printed board microprocessors will communicate with external masters. The supported communication methods are Python, Java, CANOpen protocol, and API (Application Programming Interface) in C.

These methods are quick and simple to set up. They only require a few command code strings to start communication.

High-Precision Movement Control

Two encoders that take measurements prior to and the following gearing provide feedback to servo actuators. The sensing devices keep an eye out for the changes in position and send the information they have gathered to a controller that is also located inside the servo housing.

As an intellectual hub, the controller module analyzes the feedback to determine what has to be changed to obtain the desired propulsion.


Based on sensors that are built into their brushless cores, each actuator is equipped with overtemperature protection.

Specialized safety features are offered in API and CANOpen communication interfaces in order to identify abnormal operations and stop or configure servos to respond to irregularities.
