Product Description:

Bosch Rexroth Indramat manufactures the MS2M03-B0FNN-KMDL1 as part of the MS2M Ultra Compact Motors series. This compact servo unit drives lightly loaded axes where space is limited and fast position control is essential in packaging, semiconductor, and small assembly stations. It uses natural convection for cooling, keeps overall mass at 1.7 kg, and integrates an optical 23-bit encoder that can operate in single-turn or multi-turn mode, giving drive controllers high-resolution feedback for precise closed-loop control.

The motor has a rated speed of 3000 rpm and a rated torque of 1.27 Nm; at this operating point, it draws a rated current of 2.40 A and delivers mechanical output power of 0.4 kW. When acceleration reserves are required, the rotor can reach a maximum speed of 6000 rpm, letting a single frame size cover both rapid indexing and steady processes. A five-pole-pair rotor lowers torque ripple, and the low-inertia design pairs with quick-lock SPEEDCON M17 connectors so installation remains simple and dynamic response stays fast. The shaft has a machined keyway for positive coupling, and operation is permitted between 0 °C and 40 °C so it fits standard cabinet climates.

For short bursts, the motor can supply a maximum torque of 3.82 Nm, based on a torque constant of 0.52 Nm/A(rms) and limited by a phase resistance of 1.74 Ω at 20 °C to keep copper losses in check. Electrical release of the holding brake occurs at 24 V DC, securing vertical loads when the drive is disabled. The housing is rated IP65, which prevents dust ingress and water jets from affecting internal windings, while the 65 dB(A) sound pressure level supports noise-sensitive workstations. Supply electronics reference a 4.75 to 5.25 V range for encoder power, helping maintain feedback integrity across typical control panels.
