Product Description:

The MDD041A-N-100-N2K-050GA0 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is built in the 041 frame and uses a standard housing for compact axes in pick-and-place units, packaging machines, and light assembly stations. By converting controlled DC bus energy into high-speed rotation, it delivers precise torque for velocity and position loops in automated machinery. This arrangement lets the paired controller regulate motion with accurate response during indexing, feeding, and short-stroke positioning tasks.

The motor develops a continuous stall torque of 0.64 Nm, allowing it to hold load inertia at standstill while thermal limits are respected. During operation, it can reach a nominal speed of 10,000 rpm, which suits high-cycle machinery that needs rapid acceleration and deceleration. Mechanical registration to the driven equipment is aided by a centering pilot of 50 mm. Power and feedback cabling exit on side A and terminate through a connector. This cable exit arrangement helps routing in compact machine layouts where clearance around the motor is limited. The rotor is balanced to the standard grade, the A-length stator helps keep overall mass low for gantry applications, and a shaft seal protects the front bearing from coolant or dust ingress.

For feedback, the unit uses an integrated absolute encoder, which provides single-turn position data directly to the drive without external transducers. Position retention during power loss must be provided externally because the motor is supplied without a blocking brake. Commutation and fine velocity control are handled through resolver feedback, so the drive can maintain stable motor control across changing operating conditions. Power is transmitted through a plain shaft that is present only on the drive side, while the rear end remains blank in the standard single-shaft arrangement. The plain geometry simplifies coupling installation, and the single-shaft layout keeps the non-drive end free of a second output extension.
