Yaskawa UAKA-19AK011 Servo Motor
Yaskawa UAKA-19AK011
The UAKA-19AK011 is an AC permanent magnet servo motor launched by YASKAWA for high-power industrial transmission applications. It is ideal for heavy-load scenarios such as machine tools, robots, and packaging lines that demand high torque, a wide speed range, and superior reliability. As a member of the UAKA series, this motor delivers a rated power of 18.5 kW and a peak power of 15 kW, with a rated current of approximately 93 A and a peak current of 80 A, operating at a voltage of 200 V UPS.

2. Product Features
- High Power & High Torque: With a rated power of 18.5 kW and a permanent magnet rotor, the motor delivers high torque across a wide speed range, making it suitable for heavy-duty transmission systems.
- High-Precision Position Control: The 24-bit absolute encoder achieves positioning repeatability at the ±0.01° level.
- IP67 Protection: Its dustproof and waterproof design ensures stable operation in harsh industrial environments.
- Compact Structure: Compared with traditional motors of the same power rating, the UAKA-19AK011 features a more compact footprint, enabling easy installation in space-constrained cabinets.
- Low Noise & Low Vibration: The permanent magnet synchronous structure and optimized rotor/stator design reduce operational noise to below 55 dB(A).
- Strong Compatibility: The motor can be directly paired with YASKAWA Sigma-7 and Sigma-5 series servo drives, and supports multiple communication protocols including EtherCAT, PROFINET, and Modbus-TCP.
3. Structure and Components
- Permanent Magnet Rotor: Adopts high-energy-density NdFeB permanent magnets to generate strong magnetic flux.
- Stator: Equipped with three-phase copper windings stacked with low-loss silicon steel sheets.
- Encoder: Mounted at the rear end of the motor, providing 24-bit absolute position feedback.
- Holding Brake (Optional): Locks the rotor when the motor is stopped to prevent load reversal.
- Cooling Fan: Features an internal air duct design to ensure efficient heat dissipation during long-term high-load operation.
- Terminal Block: Uses a protective terminal box that complies with the IP67 standard.
