MS2M02-B0FNN-KMDL0 by Bosch Rexroth Indramat

The MS2M02-B0FNN-KMDL0 is a synchronous servo unit manufactured by Bosch Rexroth Indramat within the MS2M Ultra Compact Motors series. It belongs to the ultra-compact motor product group and is intended to deliver precise torque in machinery that requires high power density and a minimal footprint. Integrated into closed-loop drive systems, the motor translates digitally commanded currents into tightly regulated shaft motion for positioning, indexing, or continuous process duties. This makes it suitable for compact handling axes and other installations where repeatable motion is required in limited space.

The motor uses a 23-bit optical encoder that supplies fine position feedback, and the single-turn or multi-turn design lets a controller read absolute angle across multiple revolutions without homing. Cooling relies on natural convection, eliminating the need for fans. An enclosure rated IP65 shields internal components from dust ingress and low-pressure water jets, making cabinet mounting optional in many lines. Reliable operation is specified for ambient temperatures between 0 to 40 °C. The motor has frame size 2 with frame length B, a keyed shaft without a sealing ring, and M17 quick-lock SPEEDCON connectors. It is supplied without a holding brake, and its double-cable metal lead set separates power and encoder conductors. Five internal pole pairs form the synchronous magnetic field used for controlled torque production.

The MS2M winding code supports a rated speed of 3000 rpm, aligning with drive modules that can deliver the required current at an encoder supply of 4.75 to 5.25 V. Low acoustic emissions are documented at 65 dB(A), which is helpful when the motor is installed near operators. The rotor has low motor inertia, so accelerations occur quickly with modest torque demand, which benefits pick-and-place axes and lightweight gantries. Its compact length and separated cable arrangement also help the unit fit installations with limited axis depth.
