SCARA robots are widely used in high-speed industrial automation, including electronic assembly, packaging, dispensing, inspection, laboratory automation, and precision handling applications. As manufacturers continue to demand higher productivity, smaller machine footprints, and easier system integration, the selection of the right integrated servo motor for SCARA robots has become increasingly important.
Unlike traditional servo systems that require separate motors, drives, and controllers connected through complex wiring, integrated servo motors combine the motor, driver, encoder, and communication interface into one compact unit. This design simplifies installation, reduces cabinet space, improves system reliability, and provides precise motion control for robotic applications.
However, choosing the correct integrated servo motor for a SCARA robot requires careful consideration of factors such as motor type, torque requirements, speed, control method, mechanical structure, and application environment. In practical SCARA robot designs, both integrated brushless DC servo motors and integrated stepper servo motors have their own advantages and are suitable for different operating conditions.
This guide explains how to select the right integrated servo motor for SCARA robots and how to choose between integrated BLDC servo motors and integrated stepper servo motors.
A SCARA robot typically consists of multiple rotary joints and a vertical Z-axis mechanism. Each axis requires a motor system capable of delivering accurate positioning, stable operation, and fast response.
The integrated servo motor is responsible for:
Driving robotic joints with accurate motion control
Maintaining position accuracy during high-speed operation
Providing feedback through encoders
Controlling acceleration and deceleration smoothly
Communicating with the robot controller or PLC system
Traditional servo systems require:
Servo motor
External servo drive
Encoder cable
Power cable
Communication wiring
Control cabinet installation
An integrated servo motor combines these components into a single compact solution, significantly reducing wiring complexity and improving installation efficiency.
For SCARA robots, where multiple motors are installed in limited mechanical spaces, compact integrated servo solutions provide major advantages.

The first step in selecting an integrated servo motor is calculating the required torque.
SCARA robot joints must overcome:
Arm weight
Payload weight
Acceleration force
Inertia from rotating components
External processing forces
The motor torque should be selected based on the maximum operating load rather than the average load.
Important parameters include:
Continuous torque:
The torque the motor can provide during normal operation.
Peak torque:
The maximum torque available during acceleration, emergency stops, or sudden load changes.
Rotor inertia:
The motor's ability to handle rapid speed changes.
For lightweight SCARA robots used in electronics assembly, smaller integrated servo motors may provide sufficient performance. For higher payload robots used in packaging or material handling, higher torque models are required.
When selecting an integrated servo motor for a SCARA robot, choosing between an integrated BLDC servo motor and an integrated stepper servo motor depends on the robot’s speed, accuracy, load requirements, and application environment.
