Key Features
3KW Power for Industrial Motion Control
The 3KW output level makes this servo motor suitable for machinery requiring more drive capacity than compact 400W–1.8kW servo systems while maintaining precise speed and position control.
It can be considered for applications such as CNC machine tools, automated production equipment, industrial machinery and other systems requiring controlled acceleration, deceleration and repeated positioning.
Rated Speed of 3000rpm
The motor is designed around a 3000rpm operating speed, making it suitable for applications requiring both fast response and controlled motion.
When combined with the appropriate servo drive and machine transmission system, the motor can provide controlled speed across different operating conditions.
Encoder Feedback for Closed-Loop Control
The integrated encoder provides feedback to the servo system so that the controller can compare commanded motion with actual motor movement.
This closed-loop control helps improve:
Positioning accuracy
Speed stability
Repeatability
Acceleration and deceleration control
Response to changing loads
Overall motion consistency
The final encoder type and resolution should be confirmed according to the required servo drive and application.
Fast Response and Precise Motion
PMAC servo motors are designed for applications where rapid changes in speed and position are required.
Compared with standard induction motors, a properly matched servo motor and drive system can respond more quickly to control commands, making it more suitable for precision machine movement, indexing, feeding and positioning.
Compatible Servo Drive Solution
The motor should be used with a correctly matched AC servo drive.
When selecting the drive, the following factors should be confirmed:
For a complete control solution, see our AC Servo Motor Driver with Encoder.

Precision Machinery
Servo feedback makes the motor suitable for equipment where repeatable movement and controlled acceleration are important.
Applications can include automated processing machinery, precision feeding mechanisms and other machine systems that require synchronized motion.
Industrial Automation
The motor can be integrated into automated production systems for applications such as:
Robotics and Automated Equipment
Servo motors are commonly used where a machine needs controlled movement rather than simple continuous rotation.
Depending on load, transmission design and control requirements, the 3KW servo motor can be evaluated for robotic and automated equipment requiring high-response motion control.

Important Technical Data to Confirm Before Ordering
For accurate motor and drive matching, please confirm the following parameters from the approved technical datasheet:
SL TECH can provide the corresponding technical data and dimensional drawing according to the confirmed motor configuration.
Dimensions and Installation
Correct mechanical installation is essential for stable servo performance.
Before installation, confirm the following dimensions against the approved motor drawing:
The motor shaft and driven mechanism should be properly aligned. Excessive misalignment can increase bearing load, vibration and mechanical wear.
Installation Size Drawing:

Datasheet Download:
Add a downloadable PDF containing the verified electrical parameters, dimensions, encoder information and compatible servo-drive model.
Wiring and Servo Drive Integration
The motor should be connected according to the wiring diagram supplied with the matched servo drive.
A typical servo system includes:
Controller / PLC → Servo Drive → PMAC Servo Motor → Encoder Feedback → Servo Drive
During installation, confirm:
Motor power cables and encoder feedback cables should be routed according to the servo-drive installation requirements to reduce electrical interference.
Do not use a generic wiring diagram from another servo model if the connector pinout or encoder type is different.
How to Select the Right Servo Motor
Motor power alone is not enough to determine whether a servo motor is suitable for a machine.
For correct sizing, consider:
Load Torque
Determine the continuous torque required to move the machine load.
Acceleration Torque
Applications with rapid start/stop cycles may require considerably more torque during acceleration than during steady operation.
Required Speed
Confirm the normal operating speed and maximum required speed.
Load Inertia
The inertia of the machine load should be considered when matching the motor and servo drive.
Duty Cycle
Frequent acceleration, deceleration, reversing and continuous operation all affect motor sizing.
Mechanical Transmission
Provide information about any gearbox, ball screw, belt, pulley, coupling or other transmission connected to the motor.

FAQ
What is a PMAC servo motor?
PMAC stands for Permanent Magnet AC. A PMAC servo motor uses permanent magnets in the rotor and operates as part of a closed-loop servo system with feedback from an encoder.
This allows the servo drive to control motor speed, torque and position more accurately than a conventional open-loop motor system.
Is this 3KW servo motor suitable for CNC machines?
It can be suitable for CNC machine tools and precision machinery when its torque, speed, inertia, voltage and mounting dimensions match the machine requirements.
Servo motor selection should be based on the complete machine load and motion profile rather than power alone.
Does the motor include an encoder?
Yes, this product is designed as a servo motor with encoder feedback. The exact encoder specification should be confirmed with the selected motor and servo-drive configuration before ordering.
Which servo drive should be used with the motor?
The servo drive must be matched to the motor's electrical parameters and encoder system.
Please provide your control method, power supply and machine-controller requirements so that a compatible servo drive can be selected.
Can I replace an existing servo motor with this model?
Possibly, but the existing motor's electrical and mechanical specifications need to be compared first.
Please send the old motor nameplate, model number, flange dimensions, shaft dimensions and servo-drive information for evaluation.
Can I get a motor drawing and datasheet before ordering?
Yes. Request the technical datasheet and dimensional drawing for the confirmed 3KW configuration before finalizing the motor selection.
