MS2M02-B0FNN-KMDH1
MS2M Ultra Compact Motors
The MS2M02-B0FNN-KMDH1 is an ultra-compact servo motor produced by Bosch Rexroth Indramat and positioned within the MS2M Ultra Compact Motors series. It is listed in the Ultra Compact Motor product group and targets tightly packed axes in assembly cells, pick-and-place stages, and other industrial automation tasks where small footprint and precise torque control are required.
At the mechanical output, the motor delivers a maximum torque of 0.95 Nm while its standstill capability at 60 K is 0.32 Nm. Nominal speed is set by a 3000 min-1 winding, and braking torque is provided by an electrically released brake powered at 24 V DC. Position feedback relies on an optical 23-bit encoder that operates in single- or multiturn mode; the sensor electronics and brake share a 4.75–5.25 V supply. Heat is removed by natural convection, and environmental sealing meets the IP65 rating. Wiring is completed through M17 quick-lock SPEEDCON connectors accompanied by a double-cable metal lead set. Frame size 2 with length code B is built around a 38 mm flange, facilitating direct panel mounting in multi-axis platforms.
Mechanical integration focuses on weight, dimensions, and acoustic limits. The motor weighs 0.91 kg, easing travel on lightweight carriages. A bolt circle of 45 mm aligns with M3 shaft-end mounting holes, while the spigot diameter is 30 mm. The plain shaft, produced without a sealing ring, measures 8 mm in diameter and 22 mm in length. Workplace sound pressure stays at 65 dB(A), and the design keeps rotor inertia low for quick velocity changes. Operation is specified between 0 °C and 40 °C, and passive cooling keeps component count low. These physical parameters support compact assemblies in pick-and-place modules, small gantries, and indexing drives where precise movement and quiet running are mandatory.
