MSM100-14-604-S-2KA by Kollmorgen

The MSM100-14-604-S-2KA from Kollmorgen is a compact, high-performance member of the MSM Brushless Servo Motors series designed for demanding Industrial Automation environments. This servo motor delivers a nominal Continuous Torque of 1.53 Nm (14 in-lb) and a Peak Torque of 8 Nm (71 in-lb), ensuring substantial power density in a small footprint. Operating at speeds up to 6000 rpm and featuring a Ke Voltage Constant of 62 V/KRPM, the design balances rapid acceleration with precise speed control. With a lightweight construction of just 5.9 kg (13 lb) and only 6.6 kg (14.6 lb) when equipped with its optional holding brake, this motor achieves an excellent torque-to-weight ratio. Its robust six-pole configuration further enhances smooth torque delivery and dynamic response.

In terms of technical capabilities, the motor’s Torque Constant (Kt) of 0.52 Nm/A and a Maximum Current rating of 17.7 A peak enable efficient energy conversion and sustained performance under load. The Stall Current of 3.4 A peak provides insight into inrush characteristics, while the Winding Inductance of 22 mH and Winding Resistance of 9 Ohm (phase to phase @ 25°C) are optimized for rapid current ramping and thermal stability. The Rotor Inertia of 0.00021 kg·m² (0.0019 lb·in·s²) and Rotor Inertia with Brake of 0.00032 kg·m² (0.0028 lb·in·s²) ensure precise dynamic control and minimal overshoot during motion profiles. The 6 poles configuration contributes to quiet, low-vibration operation, making this motor well-suited for high-precision tasks.

Operational features include a front and rear end bell design with slotted stator laminations that promote improved thermal dissipation and extended duty cycles. The motor’s ST-60 shaft material ensures durability and reliable torque transmission under heavy loads. An integrated single-turn encoder provides accurate position feedback, eliminating homing cycles and enhancing system uptime. The design mandates rigid coupling alignment to avoid excessive bearing loads, while the separate routing of power and signal cables mitigates electromagnetic interference. Compliance with ambient temperature limits (0°C to 40°C) and adherence to local safety requirements guarantee dependable, long-term operation.

Integration of the MSM100-14-604-S-2KA into automation architectures is straightforward: the motor requires a compatible drive system and offers standard mounting dimensions for seamless replacement of legacy units. Its high power density and low inertia profile make it ideal for robotic arms, pick-and-place machines, and CNC axes. Safety-conscious installations benefit from clear guidelines on brake engagement and connector handling to prevent electrical hazards. Designed specifically for Industrial Automation applications, this Kollmorgen servo motor delivers precision, reliability, and efficiency in a streamlined package.
