The 180JASM544315K-M23BH is a 4400W 380V Servo Motor that delivers its rated 28 N·m of torque at 1500 r/min from a 180 mm frame. A 23-bit magnetic encoder and an integrated holding brake round out a package aimed at high-load industrial motion.
As a closed loop servo, the motor depends on its encoder to sustain accurate position, speed and torque control through the matching drive. Because the controller sees the measured angle at every sample, it can reject disturbance and settle quickly during indexing or feed motion. This is what separates a servo axis from an open-loop drive when loads vary from cycle to cycle.
The 300% short-time overload capability of the 380 V family provides headroom for transient load spikes, as long as the continuous thermal budget of the frame is respected between them.
The integrated brake stops and holds the shaft when the coil is de-energized. This is particularly useful on vertical feeds and servo-driven rotary tables where the load must not drift when halted. Mounting follows the standard 180 mm flange pattern, but the heat delivered at 4400 W should be factored into the machine’s cooling layout.
The motor suits CNC machine tool servo axes, robotics joints that carry high torque, factory automation transfer and winding stations, textile and printing drives, food processing equipment, material handling, battery manufacturing, and AGV/AMR drive and steering applications.
Verify that the inertia ratio between motor and load stays within the drive’s tuning range, and confirm brake holding torque on vertical installations. As a distributor, Lyenwsin offers the 4400W 380V servo motor with matching drives, cabling and technical support to help you commission the axis correctly.
