Product Description:

The MS2M03-A0FNN-KMDL0 is an ultra-compact synchronous motor produced by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. With a compact square flange and frame size 3, the unit is intended for space-constrained axes in packaging, handling, and small machining equipment. It delivers rotary motion through a keyed shaft and supplies real-time position data through an integrated optical encoder, enabling closed-loop control when paired with a compatible Rexroth servo drive.

The motor produces up to 1.91 Nm of peak torque, while its continuous standstill torque is limited to 0.64 Nm at a 60 K temperature rise, making it suitable for light-duty positioning cycles. The mechanical interface has a bolt circle diameter of 70 mm around the 60 mm flange, and its 11 mm shaft fits standard couplings; the keyed portion extends 27 mm beyond the housing. Natural convection cooling allows operation without external fans, and low rotor inertia supports rapid acceleration when the 3000 rpm winding is driven by a compatible inverter. M17 quick-lock SPEEDCON connectors and a cable with double metal lead wires provide power, encoder, and protective earth connections.

Ingress protection is rated at IP65, so the housing resists dust penetration and low-pressure water jets when all gaskets and plugs are properly fitted. The permitted ambient temperature range is 0 to 40 °C, which is suitable for typical cabinet or machine-frame conditions. Control electronics inside the encoder require a regulated input of 4.75 to 5.25 V, supplied by the servo drive through the hybrid feedback cable. Acoustic output during free-running tests does not exceed 65 dB(A), helping limit noise in open production areas. Because the motor does not have a holding brake, applications requiring static load support must use mechanical clamping or continuous drive torque.
