Overview
The Yaskawa USAIKM-50-BK43-D is a powerful AC servo motor manufactured in Japan, structurally designed as a servo motor but practically operated as a spindle motor. Due to its high rated speed, high torque, and design for continuous operation, this motor is particularly suitable for servo-electric spindle applications in CNC machines. The design is robust, thermally resilient, and engineered for precise control at high speeds – proven reliable in continuous industrial use.
Overview
- Device category/Role: AC servo motor, used as a spindle motor
- Series/Class: Yaskawa USAIKM series, 200 V class
- Design: High-speed motor, forced-air cooled, encoder-based, suitable for industrial use
Model Designation
- USAIKM = Yaskawa Servo/Spindle Motor Series
- 50 = Frame size / Power class
- BK43 = Mechanical design (Flange, Shaft, Cooling concept)
- D = Version status
- Encoder (Original) = Incremental encoder UTMSI-10AAEAZR
- Encoder (Replacement) = ERiP-UTMSI-10AA
- Associated Inverter = Yaskawa CIMR-MXL2022
