MS2M04-B0FNN-KMDL0 by Bosch Rexroth Indramat

The MS2M04-B0FNN-KMDL0 is a servo motor manufactured by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. It is intended for position-controlled and velocity-controlled axes where installation depth is limited and compact packaging is important. Its ultra-compact design suits handling systems, packaging equipment, and small transfer axes where nearby tooling leaves little room for larger motors. Heat is removed through natural convection, and the motor is supplied without a holding brake, so stationary loads must be supported by drive torque or an external locking device. An M17 connector with a quick-lock SPEEDCON interface and a double metal leadwire cable simplify installation, while the keyed shaft without a sealing ring supports direct coupling to gearboxes or pulleys.

At its continuous operating point, the motor reaches 3000 rpm, produces 3.18 Nm, and draws 5.7 A (rms). This operating range suits compact servo axes that need stable speed and usable continuous torque without forced cooling. For acceleration and short overload periods, it can provide up to 9.55 Nm with a peak current of 17.13 A (rms), which supports brisk starts and rapid indexing moves. The performance profile is well suited to repeated start-stop duty where fast response is important. The enclosure is rated IP65, helping protect internal parts from dust and water jets in automated machinery with frequent motion cycles.

The optical feedback system provides 23-bit resolution and supports single-turn and multi-turn operation, giving the control loop precise position information for commutation and closed-loop motion. Within an ambient range of 0 to 40 °C, the motor can deliver 1 kW of continuous output when the logic supply remains between 4.75 and 5.25 V. Frame size 4 with frame length B keeps the housing short, which helps the motor fit confined machine sections. This layout is useful on pick-and-place units and other compact axes that need accurate feedback in a small installation space.
