Product Description:

The MSM100-6-604-E2-0KA is produced by Kollmorgen within the MSM Brushless Servo Motors series. It functions as a compact rotary actuator for closed-loop motion tasks in automated assembly, packaging, and materials handling equipment. The integrated incremental encoder supplies position feedback to the drive, allowing the motor to execute commanded velocities and torques on a 460-volt bus.

Its continuous torque rating is 0.72 Nm, which represents the steady load the stator can sustain without surpassing its thermal limits. At the shaft, the rotor can reach a rated mechanical speed of 6000 rpm, aligning with high-throughput cycle requirements. To achieve acceleration, the drive may command up to 9.3 A peak, while the stall current is limited to 2.0 A peak to avoid demagnetization. The magnetic topology has a pole count of 6, establishing an electrical frequency that balances torque ripple and efficiency. The copper windings generate torque in proportion to current with a constant of 0.46 Nm/A, simplifying drive tuning because each ampere produces nearly half a newton-meter of torque. The encoder has a resolution of 2,000 lines, providing 8,000 counts per revolution after quadrature decoding and supporting precise velocity control.

Dynamic response is further shaped by a peak torque capability of 3.8 Nm, leaving headroom for short bursts during indexing moves. Electrical time constants remain moderate because the phase inductance measures 48 mH and the winding resistance is 24.4 Ω, so current transitions occur cleanly when commanded by a high-voltage inverter. The rotor has an inertia of 0.00015 kg·m², while the motor has a net mass of 4.9 kg, supporting fast reversals and limiting vibration on lightweight frames. A voltage constant of 55 V/krpm allows the controller to estimate back electromotive force for sensorless monitoring. The M5 × 0.8 mm shaft thread has a depth of 12.5 mm and accommodates standard couplings for test stands or conveyor applications.
