Product Description

Bosch Rexroth’s product portfolio includes hydraulic, electric, and pneumatic drive and control technologies. The innovative manufacturer is the manufacturer of the MDD motors used in printing and packaging machines, textile machines, and robotics.

The MDD093B-F-040-N2L-110GA1 by Bosch Rexroth is an MDD model with a high power-to-weight ratio. It comes in a compact package, enclosed in a sealed housing that meets the demands of the IP 65 protection category per DIN 40 050. This means it is touch-proof, dustproof, and impervious to water jets sprayed at it from different directions. Such a housing allows its safe use directly within the working area of the machine, even under poor environmental conditions like the effects of coolants and soluble oil emulsions. It is also painted with a black prime varnish with high resistance to yellowing, weathering, and chalky buildups. The MDD model is fitted with digital servo feedback for the evaluation of its relative indirect position. This replaces separate incremental encoders.

Temperature monitoring by thermal sensors in the MDD093B-F-040-N2L-110GA1 protects it from permanent damage due to thermal overload. It is fitted with a blocking brake of 11.0Nm torque to hold the servo axis backlash-free when it is disconnected from power. This aids with the motor’s energy-efficient operation. Another feature that contributes to its energy-efficient operation is its lifetime-lubricated bearings. These bearings minimize energy losses due to friction and improve the motor’s operational reliability. The MDD motor can reach a nominal speed of 4,000 revolutions per minute and has a centering diameter of 110mm. Its shaft is plain, providing a backlash-free and non-positive torque transmission. It has a sealing ring that prevents fluids from entering the motor along the shaft.
