The Bosch Rexroth R911257081 (MDD065D-N-040-N2M-095PB1) is a model from the MDD digital AC servo motors range, which are permanent magnet-excited synchronized units with electronic commutation. They are geared for high cyclic load capacity and excellent contouring accuracies at increased feed rates, suited for consistent start-stop operations. Equipped with an integrated multiturn encoder for indirect absolute position detection, they offer form-fitted shaft-hub connections owing to a shaft with a keyway and shaft sealing ring. Predominantly maintenance-free due to their brushless design and lifetime-lubricated bearings, these motors possess an IP 65 rating, ensuring protection from solid materials and water jets. With a blocking brake and 3.0Nm torque, they hold the servo axis stably when disconnected from power. The housing boasts a resilient black varnish, a speed of 6000rpm, a 95mm standard center diameter, a top torque of 7.8Nm, and an operational ambient temperature of 0-40°C with a relative humidity limit of 95% under 1000m above sea level.
