Product Description:

The MDD090A-N-030-N2L-130GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded electrical signals into precise mechanical rotation for indexing tables, packaging machines, and material-handling axes. The unit’s permanent-magnet design supports rapid torque buildup, while its standard rotor balancing and sealed housing allow installation on industrial machinery without extra vibration damping or protective covers. Its controlled response is suited to applications that require repeatable starts, stops, and position correction during changing load conditions.

A centering diameter of 130 mm aligns the motor flange concentrically with the machine frame, limiting runout at speed. Power and feedback leads exit on side B, and the plug-in connector simplifies cable routing in confined panels. At standstill, the motor can supply 3.7 Nm of continuous torque, enabling the axis to resist load without thermal overload. When energized, it reaches a nominal velocity of 3000 rpm, matching common servo inverter outputs. Position and velocity feedback are provided through digital servo feedback, giving the drive controller high-resolution data for closed-loop correction. The compact A-length stator lowers overall mass, which helps support rapid acceleration and deceleration in repetitive motion sequences.

The motor is fitted with a blocking brake that delivers 6.5 Nm of static holding torque to secure the load during power loss or emergency stops. A shaft seal protects the bearing cavity from dust and coolant, and the frame designation 090 keeps the package narrow enough for clustered multi-axis assemblies. The drive end uses a plain shaft, so couplings can be mounted without a key. The opposite end has no secondary shaft extension, which helps keep the rear profile compact for enclosed machine layouts. Standard housing fins manage heat passively on this A-length model.
