Payload and reach
Payload, arm length, joint position, acceleration and safety margin determine torque and gearbox direction.
Servo Motor for Robot Arm
Servo motor selection for robot arms and automation
Review servo motor, BLDC motor, gearbox, encoder, brake and driver directions for robot arms, collaborative robots, handling equipment and precision motion control applications.
Selection Factors
Robot arm motors need load and motion details
Precision and feedback
Repeatability, encoder resolution, brake, homing method and control interface affect the motor and driver choice.
Duty and temperature
Cycle time, working hours, load profile and cooling space must be reviewed to avoid overheating.
FAQ
Robot arm motor questions
What is needed for servo motor selection?
Payload, arm length, joint axis, target speed, acceleration, voltage, control mode, encoder requirement and quantity.
Can you supply a complete actuator?
The project can be discussed as motor only, motor plus gearbox, or actuator module with feedback and driver matching.
How should prototype tests be planned?
Check torque, current, temperature rise, repeatability, noise, backlash, brake holding and startup under load.
Need a servo motor for a robot arm?
Send payload, reach, speed, voltage and quantity for an initial motor direction review.
