MS2M03-B0FNN-KMDH1
MS2M Ultra Compact Motors
The MS2M03-B0FNN-KMDH1 is an ultra-compact synchronous motor in the MS2M Ultra Compact Motors series from Bosch Rexroth Indramat. It supplies controlled rotary motion for positioning axes, pick-and-place heads, and other light mechanical drives where cabinet space is limited. As part of the Ultra Compact Motor group, it combines a small frame with integrated feedback and brake functions so machine builders can implement precise movement without enlarging the footprint of their servo-controlled stations.
Its electrical performance centers on a rated speed of 3000 min⁻¹ provided by windings matched to that frequency. Under continuous duty the motor outputs 0.4 kW and 1.27 Nm while drawing 2.40 A. A torque constant of 0.52 Nm/A, a voltage constant of 18.30 V(rms), and a 1.74 Ω phase resistance define the drive interface, with encoder electronics supplied from 4.75–5.25 V. Short-term demand can push current to 7.23 A and torque to 3.82 Nm. The unit relies on natural convection and low rotor inertia to control heat. A 23-bit optical encoder supports single- or multiturn tracking, and power plus feedback reach the frame-size 3, length-B housing through M17 SPEEDCON quick-lock connectors.
For installation the housing has an IP65 rating and operates from 0 to 40 °C without derating. The electrically released brake uses 24 V DC and is wired through the factory double-metal lead set. Acoustic emission is 65 dB(A) at nominal load, enabling placement near operators. A plain shaft without a sealing ring reduces friction and suits couplings with their own seals. The natural-convection design eliminates fans, keeping noise and maintenance low. The preinstalled terminals simplify commissioning by requiring only power, brake, and feedback cables to be mated to the drive. Wake Industrial supplies this motor with a one year warranty and offers a variety of shipping options.
