Product Description:

The MDD093D-N-020-N2L-130GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It integrates with digital drive controllers to convert regulated current into rotary motion for automated conveyors and packaging stations. The unit supports closed-loop operation so commanded positions and velocities stay stable under variable load conditions. This makes it suitable for automation tasks that require repeatable movement during frequent starts, stops, and speed changes.

The motor has a centering diameter of 130 mm and a D length code, providing enough stack height for moderate torque without enlarging the mounting flange. Standard dynamic balancing helps keep vibration within the limits expected in precision machinery. The rotor can deliver a continuous standstill torque of 24.0 Nm, and the winding is rated for a nominal speed of 2000 rpm, allowing stable operation across a broad speed range. Power and feedback conductors exit on the left side through a sealed connector interface, which can simplify cabinet layout when drives are arranged in rows. Position data are returned through Digital servo feedback (DSF), enabling the controller to monitor rotor angle and respond quickly to load changes. The housing dissipates heat by natural convection, so no separate blower is required for normal cooling.

In service, the motor secures static loads by means of a blocking brake that applies 11 Nm of holding torque whenever power is removed or the axis is brought to a stop. Protection against lubricant migration is provided by a shaft seal, and the drive end uses a plain shaft to simplify coupling with clamping hubs. Because only the front shaft is present, the motor uses a standard single-ended layout that avoids interference with adjacent components. The frame size code 093 keeps the overall diameter consistent with other motors in this family while allowing more thermal mass than smaller units. This layout is useful where adjacent machine elements leave limited clearance around the rear of the motor.
