Product Description:
The MSM100-6-604-E2-2KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. As a compact actuator for industrial automation, it converts electrical power into controlled rotary motion. The motor is suitable for indexing tables, pick-and-place heads, and light machine axes that require tight speed regulation and repeatable positioning.
This model delivers a continuous torque of 0.72 Nm, keeping the shaft turning without overheating during long duty cycles. It sustains a rated speed of 6000 rpm for rapid cycle completion. A stall current of 2.0 A peak supports operation at standstill, while the maximum current rises to 9.3 A peak for short accelerations. The windings are designed for a bus voltage of 460 V, allowing connection to compatible high-voltage servo drives. The motor has a torque constant of 0.46 Nm/A, indicating the amount of shaft torque produced per ampere. Its voltage constant is 55 V/kRPM, indicating the back electromotive force generated in relation to rotational speed. With a winding inductance of 48 mH, the motor resists rapid current changes, while a winding resistance of 24.4 Ω affects steady-state electrical losses. A six-pole rotor supports precise commutation, and the incremental encoder supplies digital position feedback to the control loop.
This unit can supply a peak torque of 3.8 Nm to overcome inertia during startup or sudden load increases. The holding brake releases when supplied with 24 VDC and prevents shaft drift when power is removed. Rotor inertia with the brake is 0.00026 kg·m², balancing quick acceleration with stable rotation. The motor has a total mass of 5.6 kg, so the mounting structure must support the unit securely during operation. Its shaft has an M5 × 0.8 mm threaded end for positive attachment to compatible pulleys or couplers.
