Product Description:

The MDD090A-N-040-N2L-110PB1 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers that need precise torque and speed control on automated axes in packaging, material-handling, and general machinery. The compact housing uses standard balancing and follows length code A, which gives the motor the shortest rotor stack in this frame. It is suited to applications that require fast response during repeated indexing, synchronized transport, and controlled acceleration. That short body helps the unit fit where axial space is limited and where a compact drive package is preferred near the load point.

The centering flange has a 110 mm diameter to align the housing during installation, while power and feedback conductors exit on Side B for consistent cable routing in tight machines. Standard balancing keeps vibration behavior controlled, and the motor reaches a nominal speed of 4000 rpm. At standstill, it can supply 3.7 Nm of continuous torque, and the output end includes a shaft seal that helps limit lubricant loss and contaminant entry. The motor uses a single-sided shaft arrangement, and the quick-disconnect connector termination allows electrical connection without individual wire terminations at the motor. Routing the harness from one side of the housing also helps keep cables away from nearby couplings and rotating parts.

A blocking brake rated for 6.5 Nm engages when power is removed and holds the axis during downtime or an emergency stop. Motion is regulated through Digital servo feedback (DSF), which provides rotor position data for synchronous operation and stable closed-loop response across the speed range. The output shaft uses a keyway to transfer torque into couplings without slip, and a factory-installed shaft seal helps protect the bearings from splash water. Frame size 090 gives the motor a compact cross-section that suits moving axes and gantry heads where surrounding space is limited.
