Product Description

Bosch Rexroth continues to defy the odds in drive and automation technology to provide users with reliable and efficient products. Its MDD motors are permanent magnet-excited servo motors used in machine tools, robotics, and printing machines.

The MDD112D-N-030-N2L-130GA2 is a model of Bosch Rexroth’s MDD motors. Owing to electronic commutation, it functions with high cyclic load capacity. This makes it the ideal option for continuous start-stop operations with high repetitive frequencies. The servo motor is built for longevity, as seen in its brushless design and lifetime-lubricated bearings. Another feature that aids its operational reliability is its sealed housing with an Ingress Protection rating of IP 65 in line with DIN 40 050. Its power and feedback cables also correspond with this protection category. This means that these components are dustproof, touch-proof, and safe from water jets from different directions. It reaches a nominal speed of 3,000 revolutions per minute.

Digital servo feedback in the MDD112D-N-030-N2L-130GA2 ensures that its relative indirect position can be evaluated precisely. The encoder runs with the optical measuring principle and has a system accuracy of ±0.5 angular minutes. With this encoder type, the use of a dedicated incremental encoder is not necessary. In addition, it has a data storage that stores information like the type name and control loop parameters. Hence, the time taken for the motor’s boot-up is reduced. Natural convection and surface cooling are the methods employed by this MDD model for heat dissipation. It also has a sensitive thermal sensor in its stator to monitor its temperature and prevent damage due to overheating. Its output shaft is the plain type, ensuring a non-positive shaft-hub connection with zero backlash.
