The Bosch Rexroth's MDD Synchronous Servo Motors are known for a high power-to-weight ratio, compact brushless design, operational reliability, and adaptability. One of the prominent motors in this range is the R911267191 (MDD093C-N-020-N2M-130GA0). Designed with a low inertia due to the usage of special materials for the permanent magnets in the rotor, this motor features a robust sealed housing suitable for adverse conditions, adhering to an IP 65 ingress protection rating making it dust and water-resistant. Also, the black prime coated exterior provides a shield against yellowing, chalky residues, and dilute acids. For cooling, it uses natural convection and surface cooling mechanisms. It's designed for high cyclic load capacity due to its electronic commutation, making it suitable for start-stop operations. The motor also incorporates a digital servo feedback system with an integrated multiturn absolute encoder for high precision.
