The Bosch Rexroth AC servo motor R911257959 (MDD093C-N-060-N2L-110GB2) is designed for motion control applications requiring high dynamic response. It features a torque constant of 0.30 Nm/A, winding resistance of 0.07 Ω at 20°C, and a nominal speed of 6000 min⁻¹. The motor delivers a continuous torque of 19.5 Nm under surface cooling with a continuous current of 65.2 A, and can generate up to 60.6 Nm torque at a peak current of 293.3 A. Constructed with a corrosion-resistant black coating, the unit weighs 22 kg with a centering diameter of 110 mm, includes a plain output shaft with a shaft seal, and features digital servo feedback. An integrated blocking brake with 22 Nm holding torque and a mass of 1.1 kg is provided. This motor is dust- and liquid-resistant to IP65, has insulation class F, a moment of inertia of 42 x 10⁻⁴ kg·m², and inductance of 0.7 mH. Grounding is required via PG threaded joints. The motor is compatible with designated digital drive controllers.
