MS2M03-A0FNN-KMDL1

The MS2M03-A0FNN-KMDL1 is an ultra-compact synchronous servo motor produced by Bosch Rexroth Indramat within the MS2M Ultra Compact Motors series. Designed for tight installation spaces, the unit supplies precise rotary motion for indexing tables, pick-and-place axes, and other point-to-point tasks in industrial automation. The model combines a frame size 3 stator with the short A frame length, and its low rotor inertia aids rapid acceleration without overshoot. An electrically released holding brake, powered from a dedicated 24 V DC circuit, secures the load when the drive is disabled.

Cooling is by natural convection. The motor supplies 0.64 Nm continuously at 3000 rpm while drawing 1.50 A. It tolerates short bursts up to 1.91 Nm with 4.61 A. Phase resistance is 2.78 Ω at 20 °C. Five pole pairs work with a winding designation of 3000 min⁻¹. An optical 23-bit encoder supports single-turn or multiturn feedback and operates from 4.75–5.25 V. M17 SPEEDCON quick-lock connectors and a double-cable metal lead set handle power and signals. Sound pressure remains below 65 dB(A).

The electrical time constants are influenced by the coil inductance of 13.90 mH, which moderates current ripple during rapid drive commands. With a torque constant of 0.42 Nm/A, the controller can predict the required current for load changes and exploit the motor’s low rotor inertia to shorten settling times. Environmental sealing meets the IP65 rating, permitting installation in dusty or splash-prone zones when paired with the specified shaft that includes a keyway but no sealing ring. The permissible ambient range is 0 °C to 40 °C, and safe winding temperatures are sustained across that span. The motor is classified in the Ultra Compact Motor group, so its footprint stays small even with the holding brake and high-resolution encoder integrated.
