The Bosch Rexroth R911273303 (MDD090C-N-030-N2L-110GL2) is an industrially versatile AC servo motor which features an integrated holding brake. This brake utilizes a 24-volt power supply, demonstrating clamping and release delays of 20 and 60 milliseconds respectively with an 11 Nm holding torque. The servo motor offers a balancing class of N and a centering diameter of 110, encompassed by a conventional housing structure that aids in temperature regulation through both natural convection and surface cooling. Its core features include an ohm winding resistance of 0.91 and a thermal time constant of 45 minutes, sustaining an optimum performance at a maximum temperature of +45°C. Notably, the maintenance-free motor attributes to its lubricated bearings and brushless design, providing a maximum torque of 38.9 Nm at a rotational speed of 3000 RPM. With an IP65 protection, this dust and waterproof motor have an insulation class of F. The 18kg motor also includes left-sided power connection and digital feedback.
