Product Description
Bosch Rexroth sets the bar for engineering excellence with servo motors like the synchronous types in the MDD series. These AC servo motors assure high contouring accuracies at high speed rates, especially when used for cutting at high speed ranges. Their applications include robotics, handling equipment, and transfer facilities.
The MDD112D-N-030-N2L-130GA1 is a model of the Bosch Rexroth MDD servo motors designed to reach a nominal speed of 3,000 revolutions per minute. Its brushless design minimizes the exposure of parts to wear and tear, improving its operational reliability. It is also fitted with bearings that remain lubricated throughout their service life of 30,000 operating hours. With its housing that meets the demands of the IP 65 Ingress Protection category, its use in the direct working area of the machine poses minimal risks. This housing protects the servo motor from dust ingress and the penetration of water jet sprays, ensuring its safe use in poor environmental conditions like the effects of coolants and soluble oil emulsions.
Rare-earth materials used in the construction of the permanent magnets of the rotor of the MDD112D-N-030-N2L-130GA1 give the motor a low inertia. Its rotor’s moment of inertia is 230 x 10-4 kgm2. It also has a good torque-inertia ratio for highly dynamic operations. Digital servo feedback is the integrated feedback system in this MDD model for evaluating its relative indirect position. This feedback type eliminates the need for a separate incremental encoder and uses the optical measuring principle. Electronic commutation makes this synchronous servo motor the ideal choice for continuous start-stop operations with high repetitive frequencies. The feature gives it a high cyclic load capacity, which is necessary for such operations.
