Product Description:

The MDD090B-N-040-N2L-110PB1 is a servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts finely metered three-phase currents into precisely regulated rotation for industrial automation. Machine builders deploy this motor on packaging lines, pick-and-place gantries, and indexing tables where consistent speed, repeatable stopping accuracy, and compact mechanical dimensions are needed to maintain throughput and product quality. This operating role suits axes that must start, stop, and repeat motion patterns throughout long production runs.

At rated conditions, the motor supplies a continuous stall torque of 7.2 Nm, allowing it to hold static loads without thermal overload. For safety during power loss or emergency stops, the integrated blocking brake can impose 6.5 Nm of locking torque on the rotor. When commanded to move, the shaft accelerates up to its nominal velocity of 4000 rpm, supporting short cycle times. Accurate flange alignment is aided by a 110 mm centering diameter, and the frame size 090 matches the mechanical envelope used for this motor class. A standard housing dissipates heat by convection, and a plug-in connector simplifies installation and cable routing.

The rotor is trimmed with standard balancing to limit vibration across the speed range, while digital servo feedback (DSF) transmits high-resolution position data to the drive for closed-loop control. Power and encoder leads exit on the rear through the connection on side B, which keeps the front face clear for couplings and leaves more space around the mounting area. A configuration with a shaft seal helps block fluids from the bearing cavity and protects the keyway shaft during operation. The single-ended shaft arrangement and length code B reduce axial space when only one output side is required.
