Product Description:

The MDD093B-N-040-N2L-130GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. As a closed-loop drive element, the unit converts commanded current into rotational motion so that automated axes can accelerate, position, or hold loads precisely in industrial machinery. Its standard housing and balancing scheme limit vibration, while the plain shaft and single-ended output provide a compact, backlash-free interface for pulleys, couplings, or gearboxes.

The motor delivers a continuous stall torque of 14.5 Nm, allowing stable shaft force whenever the drive issues DC holding current. When energized, the rotor can reach a nominal speed of 4000 min⁻¹, which suits applications that require rapid indexing without overspeeding the stator windings. A centering diameter of 130 mm aligns the frame concentrically against mounting flanges, reducing radial runout and wear. Frame designation 093 indicates the stator diameter, while length code B indicates the active stack depth and the resulting torque characteristics. These dimensional codes help match the motor to load inertia requirements and available installation space.

Load retention during power-off is handled by a blocking brake that supplies 22 Nm of static torque, preventing movement on vertical or suspended axes. Electrical and feedback connectors face Side A, which helps simplify cable routing inside linear guide carriages or tight enclosures. A protective shaft seal keeps lubricant and abrasive particles away from the bearing seats, and the feedback system uses digital servo feedback (DSF) to transmit high-resolution position data to the drive. The standard housing, plain shaft profile, connector-based wiring, and internal balancing support stable dynamic performance in multi-axis production cells.
