Product Description:

The MDD093B-N-040-N2L-130GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded stator current into precise mechanical motion for packaging lines, electronics assembly stations, and general material-handling axes. By combining permanent-magnet excitation with integrated sensing, the unit supplies regulated torque and velocity where tight positional accuracy and short settling times are required on the factory floor.

The motor’s continuous stall capability is rated at 14.5 Nm, allowing it to hold loads without overheating when airflow is limited by the housing’s standard cooling path. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm, enabling direct coupling to high-speed belt drives or gear stages. Accurate commutation is obtained from the integrated Digital servo feedback (DSF) device, which streams position data to the controller every cycle. Mechanical alignment to the machine frame is simplified by a centering pilot of 130 mm, and standard dynamic balancing keeps residual vibration within ISO quality grade G. The motor uses length code B for its magnetic stack depth, and the housing is the standard uncoated cast design for normal shop environments. Connections exit on the right side, matching cabinet layouts that favor downward or rearward cable routing.

For load holding when power is removed, the unit is delivered with a blocking brake that supplies 11 Nm of static torque. Power, brake, and feedback lines terminate through a single industrial connector, which keeps the electrical interface compact. The frame code 093 identifies the stator diameter group for this housing. A plain shaft with a factory-installed shaft seal helps prevent lubricant egress and protects the bearing set against spray or fine dust. The design does not include a side-B shaft extension, which helps limit overhung load.
