Product Description:

The MDD041A-N-100-N2K-050MA1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct pairing with digital drive controllers, it converts commanded current into rotational motion for positioning or speed-regulated axes in automated machinery. Its compact build allows it to fit into tight machine layouts where rapid acceleration and precise speed following are required. This makes it suitable for pick-and-place heads, small spindles, and auxiliary feed axes in larger production cells.

The motor delivers a continuous standstill torque of 0.64 Nm, which means it can sustain that torque indefinitely without overheating while locked. During motion, it reaches a nominal speed of 10,000 rpm, providing high peripheral velocity for compact tools. An integrated blocking brake supplies 1.2 Nm of static torque to secure the shaft when supply power is off. Accurate mounting is aided by a centering diameter of 50 mm, which helps keep the stator concentric with machine frames. Standard rotor balancing limits vibration at high speed, and length code A with size 041 indicates the shortest housing in this frame. The housing uses the series' standard uncooled aluminum profile, and an integrated absolute encoder returns single-turn position data to the drive.

Electrical and signal lines exit on side A, and a plug-in connector allows straightforward cable attachment. The feedback conductors share the same exit point, which helps keep routing concentrated on one side of the motor. For installations that are already protected from fluids, the unit is supplied without a shaft seal, which reduces drag at the shaft interface. Torque is transferred through a shaft with a keyway, and the motor has only one shaft end. The single shaft end leaves the non-drive side clear and helps the motor fit more easily into compact machine sections.
