Product Description

Bosch Rexroth has been lauded for its functional state-of-the-art drive and motion control units. It is the manufacturer of the MDD servo motors with a compact build and electronic commutation. They come in various speeds, sizes and torque.

The MDD093A-N-060-N2L-110GA0 is a model of the MDD servo motors with a rotor whose permanent magnets are composed of iron oxide materials. This is why it has low inertia and a torque-inertia ratio that supports highly dynamic operations. Its rotor’s moment of inertia is 22 x 10^-4 kgm². Like other MDD models, this motor’s enclosure is covered with a black prime varnish that protects it from yellowing, weathering, chalky buildup, and dilute acids. The enclosure is also touch-proof, dustproof, and protected from water jets from different directions, meeting the requirements of the IP 65 protection category according to DIN 40 050. Other components of the servo motor that meet this requirement are its power and feedback cables.

Features that contribute to the high operational reliability of the MDD093A-N-060-N2L-110GA0 include its brushless design and lifetime-lubricated bearings. It also has an inbuilt thermal sensor in its stator windings that monitor its temperature and protect it from damage due to overheating. The motor is a product of Balance Class R in line with DIN VDE 0530. Hence, it supports demanding applications like grinding machines. It also has a high power density, supporting highly dynamic operations like roller feeds for punching, pressing, and nibbling machines and tool-changing devices. This MDD model’s feedback type is digital servo feedback, detecting its relative indirect position and eliminating the use of a separate incremental encoder. The encoder’s detection range with absolute position detection is 4,096 motor revolutions.
