MS2M02-B0FNN-KMDH0
MS2M Ultra Compact Motors
The MS2M02-B0FNN-KMDH0 is an ultra-compact servo motor produced by Bosch Rexroth Indramat in the MS2M Ultra Compact Motors series. The unit belongs to the manufacturer’s Ultra Compact Motor group and is intended to provide precise rotary motion for space-limited axes in industrial automation cells, packaging equipment, and electronic assembly lines. Its low profile allows it to be mounted inside tight machine frames while still delivering closed-loop position and velocity control through an integrated optical feedback system.
The motor accepts a logic supply of 4.75 to 5.25 V, a range that feeds its encoder and electronics without an external regulator. Heat is removed solely by Natural Convection, so airflow around the housing must remain unobstructed. Position data are generated by a Optical Encoder (23 Bit); its single- or multiturn design lets the controller read absolute shaft angle after power-up. Housing gaskets achieve a IP65 rating, blocking dust and water jets. The winding is optimized for a base speed of 3000 min⁻¹, giving a balance between torque density and speed range. Mechanical details include frame length B, frame size 2, a plain shaft without a sealing ring, and construction without a holding brake. Power and feedback leave the housing through a double cable with metal sheathing, supporting EMI control in compact cabinets.
Installation work is simplified by M17 Quick lock SPEEDCON connectors that couple with a quarter-turn action and keep downtime low during service. Dynamic response is helped by the rotor’s Low Motor Inertia, allowing quick acceleration with minimal drive current overshoot. Acceptable ambient conditions range from 0 to 40 °C, so the motor can operate beside control electronics without forced ventilation. During duty operation the acoustic emission remains at or below 65 dB(A), which supports noise limits in assembly cells and laboratory production lines.
