The Bosch Rexroth MDD series, specifically the R911258171 (MDD090C-N-020-N2L-110PA1) model, features advanced, high-precision AC servo motors designed to deliver optimal contouring accuracy at high speeds. This makes them ideal for applications in robotics and machine tools. Notable features include an output shaft with keyway and sealing ring to protect against liquid ingress. Its housing is sealed to IP 65 standards, ensuring it is resistant to dust, contact, and water jet sprays. The motor also benefits from an impressive power-to-weight ratio thanks to its compact design, along with a brushless design and pre-lubricated bearings for maintenance-free operation. The rotor construction employs rare earth and iron oxide, ensuring low inertia and an excellent torque-inertia ratio. This model is fitted with a thermal sensor for heat monitoring, and uses surface cooling and natural convection for heat dissipation. With a nominal speed of 2,000 rpm, the motor also incorporates a digital servo feedback encoder system.
