MS2N04-C0BNN-AMDG0-NNANN-NN

The Bosch Rexroth Indramat MS2N04-C0BNN-AMDG0-NNANN-NN synchronous servo motor from the MS2N Synchronous Servo Motors series is engineered for high‐precision motion control in industrial automation. This compact drive unit integrates a self‐cooling design to maintain optimal thermal performance under continuous operation. Featuring a torque constant of 1.48 Nm/A and a rated speed of 3230 rpm, it delivers both rapid acceleration and stable torque output. The motor’s lightweight construction and robust insulation system ensure long‐term reliability in demanding production environments. Its high‐efficiency topology minimizes power losses while meeting stringent energy‐saving requirements.

The MS2N04-C0BNN-AMDG0-NNANN-NN is designed per B5/IM3001 mounting standards with integrated PT1000 temperature sensors for real‐time thermal monitoring. It incorporates an incremental encoder with 16 signal periods per revolution and a Hiperface interface, supporting multiturn position feedback for accurate closed‐loop control. The winding exhibits resistance of 10.9 Ω at 20 °C and inductance of 52.4 mH, optimizing electromagnetic performance across variable load profiles. With five pole pairs driving a rotor having a moment of inertia of 0.00011 kg·m², the system balances low inertia for fast response and sufficient damping for precise positioning. The overall mass of 3.7 kg underscores its favorable power‐to‐weight ratio, facilitating integration into compact actuator assemblies.

Operationally, the servo motor sustains a maximum current of 9.8 A during transient loads while consuming only 1.78 A at standstill (60 K). The self‐cooling mechanism combined with the PT1000 sensors maintains winding temperature within safe limits, even under peak demand. Its encoder design supports multiturn operation, eliminating homing cycles and improving system uptime. The robust insulation and self‐cooling construction enable continuous operation at elevated duty cycles without external fans or heat exchangers. Precise torque control at a wide speed range ensures smooth motion profiles, minimizing vibration and acoustic noise in high‐speed applications.

Integration into drive systems is facilitated by standard Hiperface communication, matching seamlessly with industry‐standard servo drives. The MS2N04-C0BNN-AMDG0-NNANN-NN motor’s compliance with B5/IM3001 mounting and PT1000 sensor interfaces simplifies mechanical and electrical installation. It is ideally suited for robotics, CNC machine tools, packaging machinery, and assembly lines where accurate positioning, dynamic response, and thermal resilience are critical. By leveraging Bosch Rexroth’s ecosystem of controllers and drives, system architects can achieve high throughput and reliable operation in compact footprints.
