Product Description:

The MDD093B-N-040-N2M-110GB1 synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides precise torque and speed control in automated machinery when paired with a compatible Indramat drive. This arrangement supports positioning and speed-regulated axes in packaging, transfer, and general production equipment. The unit has size 093 with motor length code B, giving it a compact housing for mid-power axes. A standard housing and standard dynamic balancing help reduce vibration during operation.

At standstill, it can deliver 14.5 Nm of continuous torque, allowing the drive to hold or index loads without overheating. Under rated operating conditions, the rotor reaches 4000 rpm, so the axis can achieve high linear speeds when coupled through gearheads or belts. A centering diameter of 110 mm aligns the flange with machine structures while maintaining rigidity during mounting. Power and feedback conductors exit on Side B, and the sealed connector interface simplifies cable connection in enclosed machine spaces. The shaft has a plain geometry without a second shaft end, and a factory-installed shaft seal helps keep lubricant inside the bearing chamber when the motor is exposed to coolant or dust.

Position feedback is provided by an integrated multi-turn absolute encoder, and the signal is transmitted as Digital servo feedback (DSF) so the controller receives absolute position after power-up without a homing move. Motion is held during power loss by a blocking brake that provides 11 Nm of static holding torque, which helps prevent vertical or cantilevered loads from drifting at standstill. The drivetrain connection uses a plain shaft that mates directly with hub couplings to help minimize backlash in the mechanical connection. The shaft seal also helps protect the internal cavity when the motor operates in areas where coolant or dust may be present.
