60-180ST
SL
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.
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.
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.
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.
The motor should be used with a correctly matched AC servo drive.
When selecting the drive, the following factors should be confirmed:
Motor rated power
Rated voltage
Rated current
Encoder type
Encoder resolution
Required control mode
Machine controller or PLC interface
Braking requirements
Communication protocol, if required
For a complete control solution, see our AC Servo Motor Driver with Encoder.
The 3KW 3000rpm PMAC servo motor can be used in CNC machinery that requires controlled speed and repeatable positioning.
Typical applications may include:
CNC milling machines
CNC lathes
Machining equipment
Feeding systems
Tool positioning systems
Auxiliary machine axes
For another servo solution designed for machine tools, see the 3000rpm 1800W AC Servo Motor for Machine Tools.
[Internal Link: 1800W 3000rpm Servo Motor]
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.
The motor can be integrated into automated production systems for applications such as:
Material handling
Automated positioning
Transfer equipment
Production-line mechanisms
Assembly machinery
Controlled lifting or feeding systems
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.
The product should be configured according to the actual machine and servo drive requirements.

SL TECH can provide the corresponding technical data and dimensional drawing according to the confirmed motor configuration.
Correct mechanical installation is essential for stable servo performance.
Before installation, confirm the following dimensions against the approved motor drawing:
Motor flange size
Mounting-hole pattern
Shaft diameter
Shaft length
Shaft key or coupling type
Overall motor length
Cable outlet position
Available installation space
The motor shaft and driven mechanism should be properly aligned. Excessive misalignment can increase bearing load, vibration and mechanical wear.

Datasheet Download:
Add a downloadable PDF containing the verified electrical parameters, dimensions, encoder information and compatible servo-drive model.
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:
Main power connection
Motor power cable
Encoder cable
Protective grounding
Servo enable signal
Alarm signals
Direction command
Speed or position command
Communication wiring where applicable
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.
Motor power alone is not enough to determine whether a servo motor is suitable for a machine.
For correct sizing, consider:
Determine the continuous torque required to move the machine load.
Applications with rapid start/stop cycles may require considerably more torque during acceleration than during steady operation.
Confirm the normal operating speed and maximum required speed.
The inertia of the machine load should be considered when matching the motor and servo drive.
Frequent acceleration, deceleration, reversing and continuous operation all affect motor sizing.
Provide information about any gearbox, ball screw, belt, pulley, coupling or other transmission connected to the motor.
If you are unsure whether 3KW is suitable, send us your machine data and we can help evaluate the required servo motor configuration.
If your application requires a different power range, consider the following SL TECH servo motor solutions:

Suitable for lower-power machine-tool and automation applications.
2.2KW–5.5KW Permanent Magnet AC Servo Motor for CNC
Suitable when your CNC or industrial machine requires another power level within the PMAC servo range.
5.5KW 3000rpm PMAC Servo Motor
A higher-power option for applications requiring greater motor capacity.
Servo Motor for CNC Milling and Lathe Machines
Another option for CNC motion-control applications.
Selecting a servo motor requires more than choosing a power rating. The motor, encoder, drive, controller and mechanical transmission must work together as a complete motion-control system.
SL TECH supports servo motor selection for industrial machinery and OEM equipment. Customers can provide application information, existing motor specifications or machine drawings for technical evaluation.
For a faster recommendation, please provide:

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.
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.
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.
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.
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.
Yes. Request the technical datasheet and dimensional drawing for the confirmed 3KW configuration before finalizing the motor selection.
