The Bosch Rexroth MDD Servo Motor model R911255839 (MDD093B-N-020-N2M-110PA0) is a high-performance, industrial automation component designed to work efficiently with Indramat digital drive controllers. Running at a nominal speed of 2,000 RPM and affording a maximum torque of 45.1Nm, this 110mm centering diameter unit is built for maintenance-free operation thanks to its brushless design and lifelong lubricated bearings. Equipped with a thermal sensor, it efficiently dissipates heat from internal windings to the outer casing and safeguards against thermal overload. The motor is coated with a weather-resistant, anti-chalk, non-yellowing black primer and has an IP 65 Ingress Protection rating, making it resilient to harsh environments. Its advanced digital servo feedback and multi-turn absolute encoder securely store the indirect position data after a power cut, making it ideal for high-demand, continuous start-stop operations.
