Product Description:
The MS2M03-B0FNN-KMDH1 is an ultra-compact servo motor from the MS2M Ultra Compact Motors series manufactured by Bosch Rexroth Indramat. As a low-inertia motor it provides rapid acceleration for positioning axes while remaining small enough for tight machine envelopes. The unit converts electrical energy to mechanical rotation for tasks such as pick-and-place or indexing tables in modern automation cells.
Under continuous duty the motor delivers 0.4 kW of shaft power at a rated speed of 3000 min-1; this operating point is achieved with a shaft torque of 1.27 Nm and a phase current of 2.40 A. A torque constant of 0.52 Nm/A links drive current to output torque, simplifying current-loop tuning. Heat is removed by natural convection so no external fan is required, and the aluminium frame keeps overall inertia low for fast dynamic response. The optical 23-bit encoder, selectable as single- or multiturn, feeds high-resolution feedback through the 4.75-to-5.25 V supply rail. Electrical connections are handled via M17 SPEEDCON quick-lock plugs, and a double metal leadwire cable routes power and signals in parallel while maintaining EMC compliance.
For short bursts the shaft can reach 3.82 Nm while drawing up to 7.23 A, figures governed by a phase resistance of 1.74 Ohm and a voltage constant of 18.30 V rms at 1000 rpm. An electrically released holding brake operates from 24 V DC to secure the load when power is removed, and the plain shaft is supplied without a sealing ring to minimise friction. Frame size 3 with length code B fits compact gearboxes, and the housing meets IP65 so dust and water jets cannot reach internal parts. Rated operation is allowed from 0 °C to 40 °C, the sound pressure level is 65 dB(A), and the cooling mode plus low rotor inertia keep temperature rise within limits defined for the 3000 min-1 winding.
