Top of the 380 V Range

The 180JASM555315K-M23BH is a 5500W 380V Servo Motor delivering the highest continuous output in this 180 mm family. Rated at 35 N·m at 1500 r/min, it is built for axes that must move substantial mass while keeping precise control.

High-Resolution closed loop Feedback

A 23-bit magnetic encoder reports rotor angle continuously to the companion drive, which closes the position, speed and torque loops on every sample. Unlike an open-loop stepper, the controller always knows the measured angle and corrects real error instead of assuming the commanded step occurred. The result is smoother low-speed rotation and tighter settling after heavy moves.

The family’s 300% short-time overload margin supports brief torque spikes during acceleration or reversal, provided the duty cycle lets the windings cool between peaks.

Holding Brake for Heavy Loads

The integrated brake holds the shaft stationary when de-energized, which is essential on vertical feeds and rotary tables where gravity acts on the load. Because the brake is part of the motor package, no separate shaft brake is required.

Thermal Planning

At 5500 W continuous, the windings produce significant heat. Mount the motor so the cooling arrangement receives adequate airflow and evaluate the duty cycle against the frame’s thermal limits.

Selection Considerations

Confirm that the 35 N·m continuous rating matches the worst-case load, and check the inertia ratio with your drive selection to avoid resonance. Lyenwsin supplies this unit as a distributor with application guidance, matching drives and technical support for 380 V servo retrofits and new builds.
