Yaskawa SGMKS-44A5A-MU13 AC Servo Motor
Yaskawa SGMKS-44A5A-MU13
The SGMKS‑44A5A‑MU13 is a 4.4 kW (approx. 6 HP) AC servo motor launched by YASKAWA to meet the mid-to-high power requirements of industrial automation. As a member of YASKAWA‘s X Series servo motors, it adopts a high-efficiency permanent magnet synchronous rotor and can be equipped with optional encoders or brakes, making it specially designed for high-speed, high-precision motion control applications. This model is widely used in domestic and international industrial equipment, including CNC machine tools, packaging machinery, injection molding machines, and printing equipment.

Product Features
-
High Power DensityWith a rated power of 4.4 kW packed into a 44 mm flange size, the motor features a compact footprint and lightweight design, enabling easy installation in space-constrained mechanical structures.
-
High Efficiency & Low Heat GenerationThe permanent magnet synchronous rotor integrated with advanced vector control technology achieves an efficiency of over 92%. It operates with low temperature rise, reducing the need for additional cooling systems.
-
Multiple Encoder OptionsSupports 1000–5000 ppr incremental encoders, catering to diverse requirements ranging from basic positioning tasks to high-resolution servo control applications.
-
Optional Brake ConfigurationThe standard model (MU13) is brake-free, but built-in brakes can be customized according to system safety requirements to enhance shutdown reliability.
-
Full Compatibility with YASKAWA Servo DrivesSeamlessly pairs with Sigma‑7, Sigma‑5, Sigma‑3 and other YASKAWA drives, supporting multiple control modes (position, speed, torque).
-
Modular Maintenance DesignEquipped with a detachable terminal board and standardized flange, the motor allows for quick on-site replacement or repair, minimizing equipment downtime.
Structure & Components
- Rotor: Permanent magnet synchronous rotor made of high-energy magnetic materials, delivering strong torque output.
- Stator: Three-phase windings wound with high-conductivity copper wire and insulated to meet Class F temperature resistance standards.
