Product Description

Many things distinguish Bosch Rexroth in the drive and automation industry, one of which is its dedication to high quality. Its MDD synchronous motors are compact servo motors used to create rapid-response response automation systems.

The MDD093A-N-060-N2L-110GA1 is a Bosch Rexroth MDD servo motor with a centering diameter of 110mm. It allows pinions and belt pulleys to be directly attached to its shaft thanks to the suitability of its design for applying high radial loads. This shaft is the plain type with a sealing ring to prevent fluid penetration. It provides a non-positive shaft-hub connection with zero backlash and promotes the motor’s durability. Given the brushless design of this MDD permanent magnet-excited motor, its maintenance-free operation is possible. Other features that support this are its bearings that remain lubricated throughout their service life and the presence of a thermal sensor in the motor. This sensor is integrated in its windings and monitors its temperature to prevent overload damage.

Electronic commutation is a feature of the MDD093A-N-060-N2L-110GA1 that gives it high cyclic load capacity. This means the servo motor can handle repeated stress cycles without failing due to fatigue. As a result, it is ideal for continuous start-stop operations with high repetition rates. Its digital servo feedback monitors its relative indirect position, transferring the information obtained to the drive controller. The encoder has a system accuracy of ±0.5 angular minutes and replaces separate incremental encoders. It also stores the motor type name, setting it upon startup to allow the safe operation of the drive. This MDD servo motor’s nominal speed is 6,000 revolutions per minute, while its rotor’s moment of inertia is 22 x 10^-4 kgm².
