Product Description:

The MDD090B-N-020-N2L-110GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power from a matched drive into controlled rotary motion that can be tightly coordinated with machine cycles. In automated packaging lines, pick-and-place gantries, and material-handling axes, it supplies repeatable position and velocity profiles while exchanging status data with the drive through integrated feedback electronics. Its operating concept suits axes that require repeatable starts, stops, and direction changes during continuous machine cycles.

At a continuous stall point, the rotor can deliver 7.2 Nm of torque, giving machinery adequate holding force when motion is paused but the axis remains energized. Under rated conditions, the shaft reaches a nominal speed of 2000 rpm, balancing dynamic response with service life in medium-inertia loads. A built-in blocking brake supplies up to 6.5 Nm to maintain position during power loss, and it is released automatically when current is reapplied. Position information is generated by Digital servo feedback (DSF), allowing closed-loop accuracy without a separate encoder. For mechanical alignment, the front flange has a centering diameter of 110 mm matched to standard Rexroth mounting patterns. Standard balancing and the B length code help reduce vibration while keeping the motor length moderate.

Cabling enters on the left side through a keyed industrial connector, which helps with cable routing in densely packed cabinets. The drive end uses a plain shaft with a keyway-free finish for rigid clamp couplings, and the standard shaft arrangement omits a second output on side B. A contact lip at the housing provides operation with a shaft seal, which helps limit lubricant escape and keep dust away from the bearing set. The size 090 housing integrates the brake hardware and shaft arrangement into one package that mates directly with Bosch Rexroth digital drives.
