Product Description:
The MS2M03-A0FNN-KMDH1 is a brushless servo motor manufactured by Bosch Rexroth Indramat in the MS2M Ultra Compact Motors series. Positioned within the Ultra Compact Motor product group, it suits handling, assembly, and packaging axes where depth and weight must be minimized. A low-inertia rotor works with an optical feedback device to let drive controllers reach commanded positions quickly and without overshoot, while the plain output shaft permits direct coupling to pulleys or gear stages.
Mechanical dimensions are set by frame size 3 and the short frame length A, resulting in a compact profile that reduces machine mass. Position data originate from an optical encoder rated at 23 Bit; its electronics can operate in singleturn or multiturn mode to match cycle requirements. Power and signal conductors terminate on a M17; Quick lock SPEEDCON connector pair that is pre-assembled on a double cable metal lead. The motor includes an electrically released holding brake whose coil is energised at 24 V DC, securing the shaft during power loss. Environmental sealing reaches IP65, and the stator winding supports a nominal speed of 3000 min⁻¹. Because the output shaft is supplied without a sealing ring, friction losses and maintenance demands are kept low.
Heat is removed through Natural Convection, allowing continuous duty within an ambient window of 0 to 40 Celsius without forced airflow. The encoder stage tolerates a supply window of 4.75 to 5.25 V, maintaining stable position data even with extended cable runs. Operating noise is limited to a sound pressure level of 65 dB(A), supporting installation near operators. These thermal, electrical, and acoustic limits, together with the low inertia rotor and compact frame, complete a servo package suited to densely packed multi-axis machines.
