MS2M02-A0FNN-KMDH0

The MS2M02-A0FNN-KMDH0 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MS2M Ultra Compact Motors series. As an ultra-compact drive element, it delivers servo positioning and speed control for space-limited automation axes, allowing machine builders to place motor power directly at the load without enlarging cabinet size.

This motor can generate a peak torque of 0.48 Nm, while its continuous standstill capability is 0.16 Nm; these values indicate the dynamic reserve for rapid indexing and the steady holding force at zero speed. A rated supply of 3x AC 230 V matches standard low-voltage servo inverters, and operation is permitted between 0 to 40 °C provided natural-convection cooling is unobstructed. The housing carries a IP65 rating, so dust ingress and water jets do not impair service. A 38 mm square flange with a 45 mm bolt circle simplifies drop-in mounting, and the 30 mm spigot centers the frame. The plain 8 mm shaft projects 22 mm and is tapped M3 for coupler draw bolts; no shaft seal is fitted, reducing friction. Frame size 2, length A keeps the motor length short, and the SPEEDCON M17 connectors plus double metal leadwire cable accelerate installation. An optical 23-bit single- or multiturn encoder feeds precise position feedback, while the design omits a holding brake to save length. Cooling relies on ambient airflow, and service altitude is limited to 1000 m to maintain insulation clearances.

The low-mass rotor contributes to low motor inertia, enabling fast acceleration that complements the torque figures discussed above. Logic and sensor power stay stable because the encoder accepts 4.75 to 5.25 V. Operating sound remains below 65 dB(A), so the motor adds little acoustic load to equipment enclosures. With a total mass of 0.57 kg, the unit minimizes moving load on lightweight gantries, and the 3000 min⁻¹ winding rating aligns mechanical speed with common ball-screw pitches.
