MS2M04-B0FNN-KMDL1

The MS2M04-B0FNN-KMDL1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. The unit serves as the rotary actuator in high-density automation cells, transforming controlled drive current into torque for pick-and-place stations, indexing tables, and conveyor axes. Its slim housing, reduced mass, and integral feedback package allow designers to place multiple axes side-by-side, minimizing machine width while maintaining the dynamic accuracy required by modern motion controllers.

The motor carries an electrically released holding brake that is energized at 24V DC and clamps the shaft with 3.8 Nm of torque during power-off states. Heat is removed through Natural Convection, so no forced-air hardware is necessary while the device operates within 0 to 40 Celsius ambient limits. Position data come from a Optical Encoder (23 Bit) that supports single-turn and multiturn operation, giving sub-microradian resolution for closed-loop control. Five pole pairs interact with stator windings tuned for a 3000 min⁻¹ base speed, and the rotor’s low inertia lets the axis follow rapid acceleration profiles without overshoot or hunting.

Machine integration features include M17 quick-lock SPEEDCON connectors and a double cable metal lead set sealed to IP65 for dust-tight, water-jet environments. Control electronics supply the sensor and brake circuits with 4.75 to 5.25 V, and acoustic output stays below 65 dB(A) to ease compliance with shop-floor noise limits. Class 155(F) insulation withstands elevated copper temperatures, while frame size 4 and frame length B keep the envelope short for stacking inside compact gantries. The keyed shaft is delivered without a sealing ring for direct coupling to gearheads, and the product’s ultra-compact grouping supports installations where space and payload are tightly constrained.
