3800W 380V Servo Motor 130JASM538325K-M23BH with 14.5 N·m Torque at 2500 r/min

High-Speed Output on a 130 mm Frame

The 130JASM538325K-M23BH is a 3800W 380V Servo Motor that reaches 2500 r/min from a 130 mm flange, delivering 14.5 N·m of rated torque. The 23-bit magnetic encoder supports precise closed loop control even as rotor frequency rises, and the integrated brake locks the shaft when power is removed. For builders who need high power in a tighter envelope, this avoids stepping up to a larger flange.

Encoder Resolution at Speed

High-speed operation is where encoder resolution proves its worth. The 23-bit feedback lets the drive maintain an accurate position and speed signal during fast motion, so the servo can track commanded profiles closely instead of lagging into error. This is a closed loop servo by design: measured angle is continuously compared with command, and the position, speed and torque loops correct any deviation.

The family’s short-time 300% overload margin gives headroom for transient spikes during acceleration, while the 2500 r/min rating favours machines that emphasize throughput.

Brake and Thermal Layout

The holding brake secures the load at standstill, useful on vertical or gravity-influenced axes. Because rated power is high relative to the 130 mm flange, the machine should provide airflow so the winding heat is dissipated and the motor runs within its continuous thermal rating.
