4000W 380V Servo Motor 180JASM540320K-M23BH with 19 N·m Torque at 2000 r/min

A Faster High-Voltage Servo

The 180JASM540320K-M23BH is a 4000W 380V Servo Motor that runs at 2000 r/min, faster than the 1500 r/min units in the same 180 mm family, while holding rated torque at 19 N·m. Its 23-bit magnetic encoder provides the high-resolution feedback the drive needs to keep closed loop control accurate at speed.

Why Encoder Resolution Matters at 2000 r/min

At higher rotor speeds the value of encoder feedback is clearer: the drive continuously compares commanded and measured angle, correcting deviation in position, speed and torque. This keeps motion smooth across the whole speed range instead of accumulating the step errors an open-loop drive would build up.

Like the rest of the 380 V family, the motor carries a 300% short-time overload capability, so it can handle short bursts of acceleration torque provided the thermal duty allows recovery between peaks.

Brake and Mechanical Fit

An integral holding brake locks the shaft when power is removed, which suits vertical axes and driven tables that must stay put. The 180 mm flange gives a rigid mechanical interface, and the higher rated speed makes this motor a better match for applications that need throughput as well as torque.

Selection Considerations

When the machine needs the throughput of a 2000 r/min axis, check that the gearing and load inertia allow the drive to reach speed without exceeding its current limit. Lyenwsin can supply the 4000W 380V servo motor as part of a matched drive kit, with sizing assistance for new machines or retrofits.
