Description
Product Overview
The SANKYO MK752NS302KNN10 is a high-power AC servo motor designed for precision motion-control applications. According to Nidec Sankyo service documentation, this model is rated at 7500W and is supplied without a brake. The corresponding Sankyo drawing number is R2040133101.
As part of the Sankyo servo motor range, the motor is intended for use with a compatible servo amplifier/controller and feedback system. Its 7.5 kW power rating makes it suitable for demanding positioning, indexing, rotary-axis, and industrial automation applications where stable torque and controlled motion are required.

Application Areas
This high-power servo motor can be used in equipment requiring controlled rotary motion and repeatable positioning, including:
- Industrial robots and robotic mechanisms
- Semiconductor manufacturing equipment
- Precision positioning systems
- Machine tools
- Material handling equipment
- Automated production machinery
- Rotary and indexing mechanisms
- High-load motion-control systems
For semiconductor equipment or legacy automation systems, matching the complete motor part number is particularly important. Different Sankyo motors can have similar mechanical appearances while using different electrical or feedback configurations.
Installation & Configuration
Before installation, verify the complete motor model and nameplate information against the servo amplifier being used. Do not select the drive based only on the 7.5 kW power rating.
Recommended checks include:
- Confirm the motor model is MK752NS302KNN10.
- Verify the nameplate voltage, current, speed, and torque.
- Confirm the feedback device and connector arrangement.
- Check the servo amplifier’s motor compatibility.
- Verify motor power and feedback cable pin assignments.
- Confirm the mechanical shaft, flange, coupling, and mounting dimensions.
- Check grounding and shielding before powering the system.
- Perform a low-speed test before returning the machine to normal operation.
Because this model is documented as a non-brake motor, the machine’s mechanical safety system should not depend on an integrated motor brake.
Maintenance & Inspection
For an installed unit, inspect the motor periodically for abnormal vibration, bearing noise, excessive temperature, cable damage, connector looseness, and shaft/coupling wear.
If the motor has been stored as a spare, check the shaft condition, connector condition, insulation, nameplate, and signs of corrosion before installation. If possible, perform an electrical and operational test with the correct servo amplifier and feedback configuration.
Avoid applying power directly to the motor without confirming the correct drive and wiring arrangement.
Compatibility Notes
The exact suffix MK752NS302KNN10 should be used when sourcing a replacement. Sankyo’s servo family contains multiple models with different power ratings, brake configurations, and mechanical/electrical options. For example, Nidec’s service documentation lists separate 3000W, 5000W, 7500W and other models with different configurations.
A visually similar motor should not automatically be treated as a drop-in replacement.
