MDD041B-N-100-N2G-050FB1
The MDD041B-N-100-N2G-050FB1 is a compact synchronous servo motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning or velocity-controlled axes in automated machinery, pick-and-place stations, and small handling robots. It is intended for small servo axes that need quick response and low moving inertia during repeated motion cycles. The unit uses motor size 041 and a B length code, giving it a small form factor suited to high-speed, light-duty applications without adding unnecessary mass to the drive train. This layout also helps the motor fit compact axis assemblies where installation space is limited.
The rotor can deliver a continuous standstill torque of 1.35 Nm, ensuring stable force output when the shaft is held by the control loop. When the drive is released, it can reach a nominal speed of 10,000 rpm, which supports fast indexing cycles. Power and feedback conductors exit on side B through a sealed connector, allowing short cable runs inside tight cabinets and compact machine layouts. The flange has a centering diameter of 50 mm to align the motor concentrically with gearheads or machine frames. Standard dynamic balancing helps reduce residual vibration during high-speed operation. A standard cast housing provides uniform heat dissipation without additional cooling aids.
For static holding tasks, the motor incorporates a blocking brake that supplies 1.2 Nm of torque, removing the need for external clamps during power-off states. Rotor position is detected by resolver feedback, giving analog angle data to the controller even at high acceleration. The motor uses a plain shaft and is shipped without a secondary shaft end, which simplifies coupler selection. It is also manufactured without a shaft seal, so the shaft area remains open for applications that do not require additional sealing.
