Product Description:
The MS2M04-A0FNN-KMDL1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. This low-profile unit is intended to deliver accurate torque and speed in confined machine areas such as delta robots and indexing tables in automated production lines. It converts electrical drive commands into rotational motion and can be coupled directly to gearheads or load shafts where installation space is limited.
At its continuous operating point, the motor runs at a rated speed of 3000 rpm and produces a rated torque of 2.39 Nm. This operating point corresponds to a mechanical output of 0.75 kW while drawing a rated current of 4.1 A (RMS). For short acceleration bursts, it can reach a maximum torque of 7.16 Nm, which supports fast load changes. The rotor has five pole pairs, the voltage constant is 20.7 V/1000 rpm, and the motor has frame size 4 with a compact A length. A keyed shaft without a sealing ring simplifies mechanical coupling, and heat is removed by natural convection without forced air or liquid cooling.
Peak electrical demand is handled by a maximum current of 12.3 A (RMS), and the windings have a phase inductance of 5.10 mH. The torque constant is 0.59 Nm/A (RMS), which helps the drive respond predictably during acceleration and load changes. The housing is rated IP65, allowing installation outside control enclosures when the ambient temperature remains between 0 °C and 40 °C and sound pressure stays at or below 65 dB(A). Position feedback is provided by a 23-bit optical encoder that can be configured as single-turn or multi-turn, operates from a 4.75 to 5.25 V supply, and communicates through double metal lead cables with M17 SPEEDCON quick-lock connectors. An electrically released 24 V DC holding brake secures the load when power is removed.
