MS2M04-B0FNN-KMDL0

Bosch Rexroth Indramat manufactures the MS2M04-B0FNN-KMDL0, a member of the MS2M Ultra Compact Motors series used for tightly packed, high-precision axes in industrial automation. It belongs to the internal Ultra Compact Motor product group, carries a Frame Size 4 housing, and the B-length stator. The rotor is specified with low motor inertia to support rapid acceleration cycles without overshoot, making the unit suitable for pick-and-place gantries, electronic assembly heads, and other servo positions where space and response time are constrained.

Natural convection cooling governs temperature rise, meaning no external fan or liquid loop is required. The motor delivers a continuous mechanical output of 1 kW at the rated speed of 3000 rpm; this corresponds to a rated shaft torque of 3.18 Nm while drawing 5.7 A (rms). For transient moves, the winding specified for 3000 min-1 and five pole pairs can reach a peak torque of 9.55 Nm with a permissible current surge to 17.13 A (rms). The 4.75–5.25 V auxiliary supply supports the optical encoder, and the absence of a holding brake reduces mass and inertia.

The front connector set uses M17 Quick-lock SPEEDCON plugs, and power is routed through a double metal lead-wire cable, expediting cabinet assembly. Environmental protection is rated at IP65, allowing operation against dust and water jets, provided the shaft with keyway runs without a sealing ring. Acoustic emission is limited to 65 dB(A). An optical encoder with 23 Bit resolution is available in single- or multiturn form for position feedback, and reliable performance is maintained across an ambient range of 0 to 40 Celsius without auxiliary forced cooling.
