The Bosch Rexroth R911274259 (MDD090C-N-040-N2M-130PB0) is a state-of-the-art servo motor tailored for commercial and industrial use. It operates at a nominal speed of 4000 RPM with a continuous torque at standstill of 10.4 Nm and a consistent current at standstill of 24.4 Amps. It holds a maximum theoretical torque of 58.6 Nm and a top current of 145.7 Amps. The motor's design includes a rotor moment of inertia at 0.0053 kg m2, torque constant at 20 degrees Celsius of 0.43 Nm/A, and a motor winding inductance of 1.6 millihenry. The servo motor weighs 23 kg and has an optimal operational altitude range from 0 up to 1000m and a temperature range from 0 up to 45 degrees Celsius. Enclosed within an IP65-rated housing, the motor can withstand harsh environments. However, prolonged operations under non-approved conditions may lead to damage. The motor's shaft has a diameter of 130mm and features a keyway, with power connections situated on the side. While it doesn't come fitted with a blocking brake, it can be requested upon order. Installation and operation are strictly for trained professionals.
