Product Description:

Bosch Rexroth Indramat manufactured the MDD093B-N-020-N2L-110GB2 as part of its MDD Synchronous Motors series. The model is a motor for digital drive controllers intended to supply accurate torque and speed commands to automated gantries, indexing tables, and material-handling axes. In factory settings where repeatable positioning is mandatory, the unit’s permanent-magnet rotor and stator windings translate drive current into controlled rotary motion. A standard housing and standard dynamic balancing help ensure that mechanical vibration stays within limits that servo algorithms can easily compensate.

The mechanical interface uses a centering pilot of 110 mm, allowing the motor to seat concentrically on gearboxes or machine frames. Power and feedback conductors exit on side B, and the factory-installed connector simplifies plug-and-play wiring in crowded panels. At standstill, the electromagnetic package delivers 14.5 Nm of continuous torque, so the axis can hold or slowly index heavy loads without overheating. An integrated brake supplies 22 Nm of static holding force during power-off conditions, preventing back-driving on vertical slides. Position data is returned through Digital servo feedback (DSF), enabling the drive to close high-resolution loops for repeatable placement. Motor size 093 and length code B establish overall frame dimensions, while the standard shaft end is limited to the drive side to reduce envelope length in multi-motor assemblies.

For dynamic motion, the rotor can accelerate to the rated speed of 2000 min⁻¹ without leaving the continuous torque envelope, providing a balance between throughput and thermal load. A factory-installed shaft seal keeps lubricant and contaminants out of the bearing chamber when the motor is mounted in washdown or oil-mist environments. The output side uses a plain shaft, letting designers couple the motor to clamping hubs or pulleys without the geometric constraints of keys or splines.
