Product Description:

The MS2M02-B0FNN-KMDH1 is a brushless servo motor manufactured by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series and placed in the Ultra Compact Motor product group. It delivers precise rotary motion for compact pick-and-place axes, indexing tables, and lightweight gantries where space and mass are tightly limited. A factory-installed holding brake allows the shaft to remain fixed when power is removed, making the unit suitable for vertically oriented loads or safety-related stop functions in industrial automation.

The motor mounts on a 45 mm bolt circle and is centered by a 30 mm spigot, while its flange measures 38 mm. The plain shaft projects 22 mm, has an 8 mm diameter, and includes an M3 threaded hole for positive coupling. Frame size 2 with frame length B houses a low-inertia rotor to support rapid acceleration. Continuous standstill torque is 0.32 Nm, while dynamic peaks reach 0.95 Nm. Heat is removed by natural convection, and the housing meets the IP65 ingress protection rating against dust and water. Acoustic emission is limited to 65 dB(A), which can simplify enclosure design, and operation remains stable within the specified ambient temperature range of 0 to 40 °C.

The electrically released brake requires 24 V DC and is wired through a double-cable metal lead set that terminates in M17 SPEEDCON quick-lock connectors. Position feedback comes from a 23-bit optical encoder capable of single-turn or multi-turn counting, providing fine resolution at the winding speed of 3,000 rpm. The drive logic requires only 4.75 to 5.25 V for the encoder electronics and status signaling. The shaft is delivered plain without a sealing ring, making it suitable for applications that already provide external protection. The motor has a total mass of 0.91 kg, so the actuator adds minimal inertial load to miniature linear stages and collaborative robot wrists.
