Product Description:

The MDD093C-N-040-N2M-110PL0 is a synchronous motor manufactured by Bosch Rexroth Indramat for use in the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, where it converts drive output current into rotational motion for positioning axes or spindle duties in automated machinery. In automated systems, the motor provides controlled shaft motion so the drive can regulate acceleration, speed, and stopping with high repeatability. Its design supports closed-loop operation in machines that depend on stable torque delivery and consistent positioning.

This unit reaches a nominal speed of 4000 rpm, allowing rapid cycle rates when paired with a compatible drive. Rotor position is reported by an integrated multi-turn absolute encoder, and the electronics transmit that data through Digital Servo Feedback (DSF) so the controller can close speed and position loops in real time. This feedback arrangement gives the drive continuous position information over multiple revolutions and supports accurate motion after startup. The motor is delivered without a blocking brake, so load holding during power loss must be handled by external means. A shaft with a keyway provides positive mechanical coupling to pulleys or couplings while maintaining repeatable alignment. Motor size 093 is combined with the standard housing to match the thermal envelope of the associated drive modules, and the standard shaft end on side A avoids the need for a secondary output on side B.

Balancing uses the standard grade, and the centering pilot measures 110 mm to fit flange mounts common to this frame class. The centering fit helps the motor seat accurately against the machine mounting surface. Power and feedback conductors exit on the left side through a connector that locks to the motor face, which helps keep cable routing compact. The connector arrangement also keeps the electrical interface consolidated at one side of the motor. The C length code indicates a longer active stack than shorter versions. A shaft seal is included to reduce lubricant migration into the enclosure and help limit contaminants at the shaft opening.
