Product Description:
The MSM165-93-204-E2-2KA is a brushless servo motor built by Kollmorgen for the MSM Brushless Servo Motors series. The unit has a 460 V stator winding and a factory-mounted 24 V DC holding brake for high-duty industrial positioning tasks. Its rotary design supports controlled motion in automated assembly stations, packaging modules, and material-handling gantries. An integrated incremental encoder provides 2,000 lines of feedback, allowing the connected drive to track changes in shaft position and regulate position, velocity, and torque. Because the encoder is incremental, the control system must establish a reference position after startup when the application requires an absolute machine position.
During sustained operation, the motor delivers a continuous torque of 10.5 Nm at its rated speed of 2000 rpm. The electromagnetic assembly can produce a peak torque of 34 Nm during acceleration and other short dynamic events. At peak output, the motor can draw up to 24.0 A peak from the connected drive. Its torque constant of 1.86 Nm/A relates the applied phase current to the resulting torque output and supports precise current-loop control. These operating values allow the drive to regulate rapid changes in speed and load while maintaining controlled shaft motion.
The motor has a stall current of 6.2 A peak, allowing the drive to maintain torque when the shaft is stationary. Back EMF increases with speed at 225 V/krpm, which helps determine whether an inverter is electrically compatible with the motor. The three-phase winding has an inductance of 60.0 mH, which affects current ripple and the response of the current regulator. Its winding resistance is 5.7 ohms, contributing to voltage drop and heat generation under load. A rotor inertia of 0.003 kg·m² supports short settling times during indexing moves. The threaded shaft end has an M8 × 1.25 mm thread with an effective depth of 19 mm for secure mechanical coupling. The motor weighs 13.9 kg, so its mounting structure must support both the motor mass and the forces generated during acceleration and deceleration.
