MDD093B-N-040-N2G-110GA0

The MDD093B-N-040-N2G-110GA0 synchronous motor from Bosch Rexroth Indramat integrates seamlessly into the MDD Synchronous Motors series and delivers a nominal speed of 4000 min⁻¹ for consistent rotational performance. This motor achieves a peak current of 164.8 A and a theoretical maximum torque of 45.1 Nm, providing substantial dynamic capability under high-load conditions. Built with an insulation classification of F, the winding can tolerate elevated temperatures up to 155 °C, ensuring extended duty cycles without degradation. At a mass of 16.5 kg, the compact design achieves a favorable power-to-weight ratio while maintaining robustness. The unit features an IP65 protection rating to guard against dust ingress and low-pressure water jets, making it suitable for demanding industrial environments.

The motor’s electromechanical response is defined by a windings inductance of 1.9 mH and a windings resistance of 0.20 Ω at 20 °C, allowing precise control of current transients and torque delivery. With a rotor moment of inertia of 29 × 10⁻⁴ kg·m², the system balances acceleration agility and vibration damping for smooth motion profiles. The thermal time constant of 50 (45) min provides insight into the motor’s heat dissipation characteristics, enabling accurate thermal modeling in drive controllers. At standstill, it must absorb continuous currents of 36.6 A or 50.5 A without exceeding thermal limits, making real-time current limiting essential. Resolver-based motor feedback ensures reliable position sensing, and the specified torque constant of 0.40 Nm/A at 20 °C correlates electrical input to mechanical output for predictable performance.

Designed as a motor for digital drive controllers, this unit adopts a standard housing and standard balancing, presenting a centering diameter of 110 mm for straightforward mechanical integration. The shaft seal and side A connection direction protect internal components while simplifying cable routing. Absence of a holding brake and a standard (without side B) shaft end minimizes complexity when direct coupling to gearboxes or encoders. The motor length code B and motor size 093 align with industry-standard form factors, enabling drop-in replacement and modular system upgrades. Ideal for industrial automation, the MDD093B-N-040-N2G-110GA0 excels in multi-axis robotics, CNC machining, and packaging machinery where precision, thermal endurance, and environmental resilience are critical.
