Product Description:

The MDD090A-N-040-N2M-130PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts controlled electrical power into rotary motion for positioning and speed-control tasks on automated machinery. Its electromechanical profile supports tight feedback loops and consistent running behavior in assembly lines, packaging stations, and material-handling axes. This supports stable motion in machines that cycle repeatedly throughout a production shift.

The motor reaches a nominal speed of 4000 rpm, enabling rapid indexing of light-to-medium inertia loads. During zero-speed clamping, it can supply a continuous stall torque of 3.7 Nm, which helps the axis resist steady process forces without rotation. For power-off holding, the mechanical brake provides 6.5 Nm of locking torque to limit shaft movement on vertical or suspended loads. A centering pilot of 130 mm helps align the motor housing with the driven machine surface for accurate mounting. Closed-loop regulation is handled through Digital servo feedback (DSF), allowing the controller to monitor rotor position continuously and correct small deviations during operation.

The output uses a keyway shaft profile for positive torque transmission to pulleys or couplings. Power and feedback leads terminate on a compact connector, and the cable outlet is directed to the right side of the housing for cleaner routing on face-mounted installations. An integrated multiturn absolute encoder records angular position and total revolutions, so the axis can retain position information after power interruptions. Standard dynamic balancing helps reduce vibration during rotation, while an internal shaft seal limits contaminant entry and lubricant escape. The A-length frame keeps mass and inertia low in installations where available space is limited.
