Product Description:

The MDD090A-N-040-N2L-110PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotational motion for positioning and speed-regulated axes in automated machinery. The A-length frame, size 090 housing, and standard construction make it a compact choice for packaging lines, pick-and-place gantries, and other installations that require precise torque delivery from an electrically commutated unit. Its compact layout also helps where machine space is limited and fast axis response is required.

Under rated conditions, the rotor reaches a nominal speed of 4000 rpm. This is the upper operating point the controller may call for during rapid indexing moves. When held motionless, it can supply 3.7 Nm of continuous standstill torque, which is suitable for moderate static loads without overheating. Mechanical interfaces use an ISO centering diameter of 110 mm, allowing direct coupling to gearboxes or flanges. Power and feedback conductors exit on the right side through a detachable connector, which can simplify cable routing in crowded machine layouts. Standard dynamic balancing helps keep vibration controlled during normal operation.

Position data returns through the integrated digital servo feedback interface, so the drive can close velocity and position loops without external encoders. The output shaft uses a keyway profile and includes a shaft seal to help keep coolant splash and airborne oil out of the bearing chamber. Because the design is supplied without a blocking brake, static holding must be provided by the drive or by a mechanical lock on vertical axes. The motor has a single shaft end, so side B remains closed. Its short overall depth also supports installations with limited rear clearance while keeping the motor package easy to place within compact equipment.
