Product Description:

The MS2M04-B0FNN-KMDH1 is an ultra-compact synchronous servo motor produced by Bosch Rexroth Indramat within the MS2M Ultra Compact Motors series. It is designed as a tightly packaged drive element for positioning axes and pick-and-place modules where space and weight are limited. In industrial automation lines, this motor converts commanded electrical current into precise rotary motion and can be integrated directly with compatible drive controllers and closed-loop feedback systems. Its compact format also helps reduce moving mass on high-cycle axes.

The mechanical interface uses a flange that measures 80 mm square, with a 90 mm bolt circle around a 70 mm spigot for compact gearbox mounting. A plain shaft without a sealing ring has a 19 mm diameter and 32 mm length for couplings, while frame size 4 and frame length B keep the overall envelope short. Cooling is handled by natural convection, and the housing is rated IP65 so dust and water jets do not reach the internal windings. Peak mechanical output reaches 9.55 Nm. The electrically released holding brake uses 24 V DC, and the electrical connections are routed through M17 SPEEDCON quick-lock connectors shared with the power conductors.

Feedback is provided by a 23-bit encoder with single-turn or multi-turn evaluation, and the encoder draws logic power from 4.75 to 5.25 V. The motor can operate at altitudes up to 1000 m with an ambient temperature range of 0 to 40 °C. Its sound pressure level is 65 dB(A), which supports use in compact machine sections where noise must stay controlled. The rated speed is 3000 rpm, and the winding supports accurate command tracking during fast incremental moves and small load changes. This combination of speed and feedback resolution helps the axis maintain stable position updates during short indexing cycles.
