The Bosch Rexroth MDD Servo Motors are noted for their low inertia, achieved through the use of uniquely constructed permanent magnets. Used in conjunction with Indramat drive controllers, these motors facilitate swift automation system responses. The R911261998 (MDD093A-N-020-N2M-110GA1) variant is a compact model with high cyclic load capacity, ideal for frequent start-stop operations. The motor is encased in a sealed housing, coated with a prime black varnish to resist environmental hazards, and meets an IP 65 Ingress Protection rating. An inbuilt thermal sensor prevents overheating. The motor has both natural convection and surface cooling systems. The R911261998 (MDD093A-N-020-N2M-110GA1) features a brushless design and lifetime-lubricated bearings for maintenance-free operation. It uses a digital servo feedback with an integrated multiturn absolute encoder for enhanced accuracy. Furthermore, it has an 11.0Nm block brake for backlash-free servo axis holding in case of power loss. The optimal operating temperature is 0oC to 45oC, perfect for altitudes up to 1,000m.
