The Bosch Rexroth R911251021 (MDD090A-N-030-N2L-110GA0) AC servomotor is a digital, rapid-response automation system that combines with a drive controller for cost-effective operation. Ideal for high-precision tasks like operating grinding machines, the motor has an electronic commutation and is built without brushes, allowing it to perform reliably under adverse conditions. Its resilience to overload comes from an integrated temperature sensor, and its high dynamics are due to an advantageous torque to inertia mass ratio. The motor structure includes a floating bearing on side A, and a fixed one on side B. The unit doesn't have a blocking brake and the maximum installation altitude is 1000m above sea level. Balancing is achieved with a reduction-balance class, and the device parameters are stored within the motor's feedback data storage capacities. Suitable for applications needing high synchronism, the motor comes with a one-year warranty and is shipped via trusted freight carriers.
