MS2M03-A0FNN-KMDL0 by Bosch Rexroth Indramat

The MS2M03-A0FNN-KMDL0 is an ultra-compact synchronous motor produced by Bosch Rexroth Indramat within the MS2M Ultra Compact Motors series. The unit provides rotary actuation for packaging stations, pick-and-place axes, and small gantry systems where limited space and light moving masses call for a low-inertia drive element. It relies on natural convection for heat removal, so it can be installed without external fans, and its sealed housing allows direct mounting on machine frames exposed to dust and coolant splash.

The motor attaches to gearboxes or machine plates through a bolt circle of 70 mm, while the 60 mm square flange aligns with standard miniature servo layouts. This compact footprint is complemented by M17 SPEEDCON quick-lock connectors that shorten cable connection time. Position feedback comes from an optical encoder with a resolution of 23-bit, and the single-turn or multi-turn design lets controllers recover absolute shaft position after power loss. Under peak demand, the rotor can deliver up to 1.91 Nm of torque, and the enclosure carries a protection rating of IP65 to keep internal components sealed against dust and water jets during washdown cycles.

At standstill, the motor sustains a torque of 0.64 Nm, which is adequate for holding lightweight loads without an integrated brake. The keyed shaft measures 11 mm in diameter and 27 mm in length, and it exits the housing without a sealing ring, so external labyrinth seals or coupling guards should be used in wet environments. The encoder electronics are powered by a logic supply between 4.75 to 5.25 V, ensuring stable operation across the 0 °C to 40 °C ambient range. During operation, the sound pressure stays under 65 dB(A), and a 50 mm spigot centers the frame A, size 3 body on the mounting surface.
