MDD071A-N-040-N2S-095GB0

Product Description

Bosch Rexroth is a trusted designer and manufacturer of state-of-the-art drive and motion control units, such as the MDD servo motors. These motors with electronic commutation form rapid-response automation systems with Indramat digital drive controllers.

The MDD071A-N-040-N2S-095GB0 is one of the synchronous motors in Bosch Rexroth’s MDD series. It is built for durability and longevity, as seen in its brushless design and bearings, which stay lubricated throughout their service life. Because it is enclosed in a housing that prevents the penetration of dust and water jets, it has an IP 65 Ingress Protection rating according to DIN 40 050. This is one reason why it can function within the direct working area of the machine, even under poor environmental conditions. In addition, its power and feedback cables correspond to this protection standard. The motor’s relative indirect position is evaluated via digital servo feedback with a system accuracy of ±0.5 angular minutes. It uses the optical measurement principle to deliver high-level precision.

Natural convection and surface cooling are two mechanisms utilized by the MDD071A-N-040-N2S-095GB0 for the elimination of heat. It also allows pinions and belt pulleys to be directly attached to its shaft since its design permits the application of high radial loads. The motor’s shaft is plain, providing a non-positive shaft-hub connection with zero backlash. This shaft comes with a sealing ring that protects the motor from fluids that can penetrate to cause damage. There is a thermal sensor in the windings of this MDD model to monitor its temperature and prevent permanent damage due to overheating. Its nominal speed is 4,000 revolutions per minute, while its rotor’s moment of inertia is 4.4 x 10^-4 kgm².
